+ Title: Reduce service costs using Azure Advisor

+description: Use Azure Advisor to optimize the cost of your Azure deployments.

+# Reduce service costs by using Azure Advisor

+Azure Advisor helps you optimize and reduce your overall Azure spend by identifying idle and underutilized resources. You can get cost recommendations from the **Cost** tab on the Advisor dashboard.

+1. Sign in to the [**Azure portal**](https://portal.azure.com).

+1. Search for and select [**Advisor**](https://aka.ms/azureadvisordashboard) from any page.

+1. On the **Advisor** dashboard, select the **Cost** tab.

+## Optimize virtual machine (VM) or virtual machine scale set (VMSS) spend by resizing or shutting down underutilized instances

+Although certain application scenarios can result in low utilization by design, you can often save money by managing the size and number of your virtual machines or virtual machine scale sets.

+Advisor uses machine-learning algorithms to identify low utilization and to identify the ideal recommendation to ensure optimal usage of virtual machines and virtual machine scale sets. The recommended actions are shut down or resize, specific to the resource being evaluated.

+### Shutdown recommendations

+Advisor identifies resources that weren't used at all over the last seven days and makes a recommendation to shut them down.

+* Recommendation criteria include **CPU** and **Outbound Network utilization** metrics. **Memory** isn't considered since we found that **CPU** and **Outbound Network utilization** are sufficient.

+* The last seven days of utilization data are analyzed. You can change your lookback period in the configurations. The available lookback periods are 7, 14, 21, 30, 60, and 90 days. After you change the lookback period, it might take up to 48 hours for the recommendations to be updated.

+* Metrics are sampled every 30 seconds, aggregated to 1 min and then further aggregated to 30 mins (we take the max of average values while aggregating to 30 mins). On virtual machine scale sets, the metrics from individual virtual machines are aggregated using the average of the metrics across instances.

+* A shutdown recommendation is created if:

+ * P95 of the maximum value of CPU utilization summed across all cores is less than 3%

+ * P100 of average CPU in last 3 days (sum over all cores) <= 2%

+ * Outbound Network utilization is less than 2% over a seven-day period

+### Resize SKU recommendations

+Advisor recommends resizing virtual machines when it's possible to fit the current load on a more appropriate SKU, which is less expensive (based on retail rates). On virtual machine scale sets, Advisor recommends resizing when it's possible to fit the current load on a more appropriate cheaper SKU, or a lower number of instances of the same SKU.

+* Recommendation criteria include **CPU**, **Memory**, and **Outbound Network utilization**.

+* The last 7 days of utilization data are analyzed. You can change your lookback period in the configurations. The available lookback periods are 7, 14, 21, 30, 60, and 90 days. After you change the lookback period, it might take up to 48 hours for the recommendations to be updated.

+* Metrics are sampled every 30 seconds, aggregated to 1 minute, and then further aggregated to 30 minutes (taking the max of average values while aggregating to 30 minutes). On virtual machine scale sets, the metrics from individual virtual machines are aggregated using the average of the metrics for instance count recommendations, and aggregated using the max of the metrics for SKU change recommendations.

+* An appropriate SKU (for virtual machines) or instance count (for virtual machine scale set resources) is determined based on the following criteria:

+ * Performance of the workloads on the new SKU won't be impacted.

+ * Target for user-facing workloads:

+ * P95 of CPU and Outbound Network utilization at 40% or lower on the recommended SKU

+ * P100 of Memory utilization at 60% or lower on the recommended SKU

+ * Target for non user-facing workloads:

+ * P95 of the CPU and Outbound Network utilization at 80% or lower on the new SKU

+ * P100 of Memory utilization at 80% or lower on the new SKU

+ * The new SKU, if applicable, has the same Accelerated Networking and Premium Storage capabilities

+ * The new SKU, if applicable, is supported in the current region of the Virtual Machine with the recommendation

+ * The new SKU, if applicable, is less expensive

+ * Instance count recommendations also take into account if the virtual machine scale set is being managed by Service Fabric or AKS. For service fabric managed resources, recommendations take into account reliability and durability tiers.

+* Advisor determines if a workload is user-facing by analyzing its CPU utilization characteristics. The approach is based on findings by Microsoft Research. You can find more details here: [Prediction-Based Power Oversubscription in Cloud Platforms - Microsoft Research](https://www.microsoft.com/research/publication/prediction-based-power-oversubscription-in-cloud-platforms/).

+* Based on the best fit and the cheapest costs with no performance impacts, Advisor not only recommends smaller SKUs in the same family (for example D3v2 to D2v2), but also SKUs in a newer version (for example D3v2 to D2v3), or a different family (for example D3v2 to E3v2).

+* For virtual machine scale set resources, Advisor prioritizes instance count recommendations over SKU change recommendations because instance count changes are easily actionable, resulting in faster savings.

+### Burstable recommendations

+We evaluate if workloads are eligible to run on specialized SKUs called **Burstable SKUs** that support variable workload performance requirements and are less expensive than general purpose SKUs. Learn more about burstable SKUs here: [B-series burstable - Azure Virtual Machines](../virtual-machines/sizes-b-series-burstable.md).

+A burstable SKU recommendation is made if:

+* The average **CPU utilization** is less than a burstable SKUs' baseline performance

+ * If the P95 of CPU is less than two times the burstable SKUs' baseline performance

+ * If the current SKU doesn't have accelerated networking enabled, since burstable SKUs don't support accelerated networking yet

+ * If we determine that the Burstable SKU credits are sufficient to support the average CPU utilization over 7 days. You can change your lookback period in the configurations.

+The resulting recommendation suggests that a user should resize their current virtual machine or virtual machine scale set to a burstable SKU with the same number of cores. This suggestion is made so a user can take advantage of lower cost and also the fact that the workload has low average utilization but high spikes in cases, which can be best served by the B-series SKU.

+Advisor shows the estimated cost savings for either recommended action: resize or shut down. For resize, Advisor provides current and target SKU/instance count information.

+To be more selective about the actioning on underutilized virtual machines or virtual machine scale sets, you can adjust the CPU utilization rule by subscription.

+In some cases recommendations can't be adopted or might not be applicable, such as some of these common scenarios (there might be other cases):

+* Virtual machine or virtual machine scale set has been provisioned to accommodate upcoming traffic

+* Virtual machine or virtual machine scale set uses other resources not considered by the resize algorithm, such as metrics other than CPU, Memory and Network

+* Specific testing being done on the current SKU, even if not utilized efficiently

+* Need to keep virtual machine or virtual machine scale set SKUs homogeneous

+* Virtual machine or virtual machine scale set being utilized for disaster recovery purposes

+In such cases, simply use the Dismiss/Postpone options associated with the recommendation.

+### Limitations

+* The savings associated with the recommendations are based on retail rates and don't take into account any temporary or long-term discounts that might apply to your account. As a result, the listed savings might be higher than actually possible.

+* The recommendations don't take into account the presence of Reserved Instances (RI) / Savings plan purchases. As a result, the listed savings might be higher than actually possible. In some cases, for example in the case of cross-series recommendations, depending on the types of SKUs that reserved instances have been purchased for, the costs might increase when the optimization recommendations are followed. We caution you to consider your RI/Savings plan purchases when you act on the right-size recommendations.

+We're constantly working on improving these recommendations. Feel free to share feedback on [Advisor Forum](https://aka.ms/advisorfeedback).

+## Configure VM/VMSS recommendations

+You can adjust Advisor virtual machine (VM) and Virtual Machine Scale Sets recommendations. Specifically, you can set up a filter for each subscription to only show recommendations for machines with certain CPU utilization. This setting will filter recommendations but will not change how they are generated.

+> [!NOTE]

+> If you don't have the required permissions, the option is disabled in the user interface. For information on permissions, see [Permissions in Azure Advisor](permissions.md).

+To adjust Advisor VM/Virtual Machine Scale Sets right sizing rules, follow these steps:

+1. From any Azure Advisor page, click **Configuration** in the left navigation pane. The Advisor Configuration page opens with the **Resources** tab selected, by default.

+1. Select the **VM/Virtual Machine Scale Sets right sizing** tab.

+1. Select the subscriptions youΓÇÖd like to set up a filter for average CPU utilization, and then click **Edit**.

+1. Select the desired average CPU utilization value and click **Apply**. It can take up to 24 hours for the new settings to be reflected in recommendations.

+ Title: 'Use your image data with Azure OpenAI Service in Azure OpenAI Studio'

+# Use your image data for Azure OpenAI by using GPT-4 Turbo with Vision (preview) in Azure OpenAI Studio

+Use this article to learn how to provide your own image data for GPT-4 Turbo with Vision, the vision model in Azure OpenAI Service. GPT-4 Turbo with Vision on your data allows the model to generate more customized and targeted answers by using Retrieval Augmented Generation (RAG), based on your own images and image metadata.

+> After the GPT4-Turbo with Vision preview model is deprecated, you'll no longer be able to use Azure OpenAI on your image data. To implement a RAG solution with image data, see the [sample on GitHub](https://github.com/Azure-Samples/azure-search-openai-demo/).

+## Prerequisites

+* An Azure subscription. [Create one for free](https://azure.microsoft.com/free/cognitive-services).

+* Access granted to Azure OpenAI in the desired Azure subscription.

+ Currently, access to this service is granted only by application. You can apply for access to Azure OpenAI by [completing the form](https://aka.ms/oai/access). Open an issue on this repo to contact us if you have a problem.

+* An Azure OpenAI resource with the GPT-4 Turbo with Vision model deployed. For more information about model deployment, see the [resource deployment guide](../how-to/create-resource.md).

+* At least the [Cognitive Services Contributor role](../how-to/role-based-access-control.md#cognitive-services-contributor) assigned to you for the Azure OpenAI resource.

+Go to [Azure OpenAI Studio](https://oai.azure.com/) and sign in with credentials that have access to your Azure OpenAI resource. During or after the sign-in workflow, select the appropriate directory, Azure subscription, and Azure OpenAI resource.

+In the pane that appears after you select **Add a data source**, you have three options for selecting a data source:

+* [Azure AI Search](#add-your-data-by-using-azure-ai-search)

+* [Azure Blob Storage](#add-your-data-by-using-azure-blob-storage)

+* [Your own image files and image metadata](#add-your-data-by-uploading-files)

+All three options use an Azure AI Search index to do an image-to-image search and retrieve the top search results for your input prompt image. For the **Azure Blob Storage** and **Upload files** options, Azure OpenAI generates an image search index for you. For **Azure AI Search**, you need to have an image search index. The following sections contain details on how to create the search index.

+### Turn on CORS

+When you're adding a data source for the first time, you might see a red notice that asks you to turn on cross-origin resource sharing (CORS). To stop the warning, select **Turn on CORS** so that Azure OpenAI can access the data source.

+You can manually upload your image files and enter metadata for them manually by using Azure OpenAI. This capability is especially useful if you're experimenting with a small set of images and want to build your data source.

+1. Go to and select the **Add a data source** button in Azure OpenAI as [described earlier](#add-your-data-source). Then select **Upload files**.

+1. Select your subscription. Select a Blob Storage account where you want to store your uploaded image files. Select an Azure AI Search resource that will contain your newly created image search index. Enter the image search index name of your choice.

+ After you fill in all the values, select the two checkboxes at the bottom to acknowledge incurring usage, and then select **Next**.

+ :::image type="content" source="../media/use-your-image-data/completed-data-source-file-upload.png" alt-text="Screenshot that shows the completed boxes for selecting an Azure Blob Storage subscription." lightbox="../media/use-your-image-data/completed-data-source-file-upload.png":::

+1. Select **Browse for a file** to select image files that you want to use from your local directory.

+1. After you select your image files, they appear in the table. Select **Upload files**. After you upload the files, confirm that the status for each is **Uploaded**. Then select **Next**.

+ :::image type="content" source="../media/use-your-image-data/uploaded-files.png" alt-text="Screenshot that shows uploaded files." lightbox="../media/use-your-image-data/uploaded-files.png":::

+1. For each image file, enter the metadata in the provided description boxes. Then select **Next**.

+ :::image type="content" source="../media/use-your-image-data/add-metadata.png" alt-text="Screenshot that shows boxes for metadata entry." lightbox="../media/use-your-image-data/add-metadata.png":::

+1. Review all the information to make sure that it's correct. Then select **Save and close**.

+## Add your data by using Azure AI Search

+If you have an existing [Azure AI Search](/azure/search/search-what-is-azure-search) index, you can use it as a data source. If you don't already have a search index created for your images, you can create one by using the [AI Search vector search repository on GitHub](https://github.com/Azure/cognitive-search-vector-pr). This repo provides you with scripts to create an index with your image files.

+This option is also useful if you want to create your data source by using your own files like the previous option, and then come back to the playground experience to select the data source that you created but haven't added yet.

+1. Go to and select the **Add a data source** button in Azure OpenAI as [described earlier](#add-your-data-source). Then select **Azure AI Search**.

+ > [!TIP]

+ > You can select an image search index that you created by using the **Azure Blob Storage** or **Upload files** option.

+1. Select your subscription and the Azure AI Search service that you used to create the image search index.

+1. Select the Azure AI Search index that you created with your images.

+1. After you fill in all the values, select the two checkboxes at the bottom to acknowledge the charges incurred from using GPT-4 Turbo with Vision vector embeddings and Azure AI Search. Then select **Next**.

+ :::image type="content" source="../media/use-your-image-data/completed-data-source-cognitive-search.png" alt-text="Screenshot that shows the completed boxes for using an Azure AI Search index." lightbox="../media/use-your-image-data/completed-data-source-cognitive-search.png":::

+1. Review the details, and then select **Save and close**.

+## Add your data by using Azure Blob Storage

+If you have an existing [Azure Blob Storage](/azure/storage/blobs/storage-blobs-introduction) container, you can use it to create an image search index. If you want to create a new container, see the [Blob Storage quickstart](/azure/storage/blobs/storage-quickstart-blobs-portal) documentation.

+The option of using a Blob Storage container is especially useful if you have a large number of image files and you don't want to manually upload each one.

+If you don't already have a Blob Storage container populated with these files, and you want to upload your files one by one, you can upload the files by using Azure OpenAI Studio instead.

+Before you start adding your Blob Storage container as your data source, make sure that it contains all the images that you want to ingest. Also make sure that it contains a JSON file that includes the image file paths and metadata.

+>

+> * Have a file name that starts with the word *metadata*, all in lowercase without a space.

+After you have a Blob Storage container that's populated with image files and at least one metadata JSON file, you're ready to add the container as a data source:

+1. Go to and select the **Add a data source** button in Azure OpenAI as [described earlier](#add-your-data-source). Then select **Azure Blob Storage**.

+1. Select your subscription, Azure Blob Storage, and a storage container. You also need to select an Azure AI Search resource, because a new image search index will be created in this resource group. If you don't have an Azure AI Search resource, you can create a new one by using the link below the dropdown list.

+1. In the **Index name** box, enter a name for the search index.

+ > The name of the index is suffixed with `ΓÇôv`, to indicate that this index has image vectors extracted from the provided images. The description filed in *metadata.json* will be added as text metadata in the index.

+1. After you fill in all values, select the two checkboxes at the bottom to acknowledge the charges incurred from using GPT-4 Turbo with Vision vector embeddings and Azure AI Search. Then select **Next**.

+ :::image type="content" source="../media/use-your-image-data/data-source-fields-blob-storage.png" alt-text="Screenshot that shows the data source selection boxes for Blob Storage." lightbox="../media/use-your-image-data/data-source-fields-blob-storage.png":::

+1. Review the details, and then select **Save and close**.

+## Use your ingested data with your GPT-4 Turbo with Vision model

+After you connect your data source by using any of the three methods listed earlier, the data ingestion process takes some time to finish. An icon and a **Ingestion in progress** message appear as the process progresses.

+After the ingestion finishes, confirm that a data source is created. The details of your data source appear, along with the name of your image search index.

+Now this ingested data is ready to be used as the grounding data for your deployed GPT-4 Turbo with Vision model. Your model will use the top retrieval data from your image search index and generate a response specifically adhered to your ingested data.

+## Additional tips

+### Add and remove data sources

+Azure OpenAI currently allows only one data source to be used for each chat session. If you want to add a new data source, you must remove the existing data source first. Remove it by selecting **Remove data source** under your data source information.

+When you remove a data source, a warning message appears. Removing a data source clears the chat session and resets all playground settings.

+> [!IMPORTANT]

+> If you switch to a model deployment that doesn't use the GPT-4 Turbo with Vision model, a warning message appears for removing a data source. Removing a data source clears the chat session and resets all playground settings.

+Use this article to learn how to automate resource deployment for Azure OpenAI Service On Your Data. The Azure Developer CLI (`azd`) is an open-source command-line tool that streamlines provisioning and deploying resources to Azure by using a template system. The template contains infrastructure files to provision the necessary Azure OpenAI resources and configurations. It also includes the completed sample app code.

+- An Azure subscription. [Create one for free](https://azure.microsoft.com/free/cognitive-services).

+ Azure OpenAI requires registration and is currently available only to approved enterprise customers and partners. For more information, see [Limited access to Azure OpenAI Service](/legal/cognitive-services/openai/limited-access?context=/azure/ai-services/openai/context/context). You can apply for access to Azure OpenAI by [completing the form](https://aka.ms/oai/access). Open an issue on this repo to contact us if you have a problem.

+- The Azure Developer CLI [installed](/azure/developer/azure-developer-cli/install-azd) on your machine.

+1. For the steps ahead, clone and initialize the template:

+2. The `azd init` command prompts you to create an environment name. This value is used as a prefix for all Azure resources that Azure Developer CLI creates. The name:

+ - Must be unique across all Azure subscriptions.

+ - Must be 3 to 24 characters.

+ - Can contain numbers and lowercase letters only.

+1. Sign in to Azure:

+1. Provision and deploy the Azure OpenAI resource to Azure:

+1. The Azure Developer CLI prompts you for the following information:

+ - `Subscription`: The Azure subscription that your resources are deployed to.

+ - `Location`: The Azure region where your resources are deployed.

+ > The sample `azd` template uses the `gpt-35-turbo-16k` model. A recommended region for this template is East US, because different Azure regions support different OpenAI models. For more details about model support by region, go to the [Azure OpenAI Service Models](/azure/ai-services/openai/concepts/models) support page.

+ The provisioning process might take several minutes. Wait for the task to finish before you proceed to the next steps.

+1. Select the link in the `azd` outputs to go to the new resource group in the Azure portal. The following top-level resources should appear:

+ - An Azure OpenAI service with a deployed model

+ - An Azure Storage account that you can use to upload your own data files

+ - An Azure AI Search service configured with the proper indexes and data sources

+The `azd` template provisioned all of the required resources for you to chat with your own data, but you still need to upload the data files that you want to make available to your AI service:

+1. Go to the new storage account in the Azure portal.

+1. On the left menu, select **Storage browser**.

+1. Select **Blob containers**, and then go to the **File uploads** container.

+1. Select the **Upload** button at the top of the pane.

+> The search indexer is set to run every five minutes to index the data in the storage account. You can wait a few minutes for the uploaded data to be indexed, or you can manually run the indexer from the search service page.

+After you run the `azd` template and upload your data, you're ready to start using Azure OpenAI On Your Data. For code samples that you can use to build your applications, see the [quickstart article](../use-your-data-quickstart.md).

+description: Learn about the best practices for using Azure OpenAI On Your Data, along with how to fix common problems.

+This article can help guide you through common problems in developing a solution by using Azure OpenAI Service On Your Data, a feature that allows you to use the power of OpenAI models with your own data. By following the best practices and tips in this article, you can optimize your output with Azure OpenAI On Your Data and achieve the best AI quality possible.

+## Azure OpenAI On Your Data: Workflow

+The workflow for Azure OpenAI On Your Data has two major parts:

+* **Data ingestion**: This is the stage where you connect your data with Azure OpenAI On Your Data. In this stage, user documents are processed and broken down into smaller chunks and then indexed. The chunks are 1,024 tokens by default, but more chunking options are available.

+ Also in this stage, you can choose an embedding model to use for creation of embeddings or preferred search type. Embeddings are representations of values or objects (like text, images, and audio) that are designed to be consumed by machine learning models and semantic search algorithms.

+

+ The output of this process is an index that will later be used for retrieving documents during inferencing.

+* **Inferencing**: This is the stage where users chat with their data by using a studio, a deployed web app, or direct API calls. In this stage, users can set various model parameters (such as `temperature` and `top_P` ) and system parameters (such as `strictness` and `topNDocuments`).

+Think of ingestion as a separate process before inferencing. After the index is created, Azure OpenAI On Your Data goes through the following steps to generate a good response to user questions:

+1. **Intent generation**: Azure OpenAI On Your Data generates multiple search intents by using user questions and conversation history. It generates multiple search intents to address any ambiguity in users' questions, add more context by using the conversation history to retrieve holistic information in the retrieval stage, and provide any additional information to make the final response thorough and useful.

+2. **Retrieval**: By using the search type provided during the ingestion, Azure OpenAI On Your Data retrieves a list of relevant document chunks that correspond to each of the search intents.

+3. **Filtration**: Azure OpenAI On Your Data uses the strictness setting to filter out the retrieved documents that are considered irrelevant according to the strictness threshold. The `strictness` parameter controls how aggressive the filtration is.

+4. **Reranking**: Azure OpenAI On Your Data reranks the remaining document chunks retrieved for each of the search intents. The purpose of reranking is to produce a combined list of the most relevant documents retrieved for all search intents.

+5. **Parameter inclusion**: The `topNDocuments` parameter from the reranked list is included in the prompt sent to the model, along with the question, the conversation history, and the role information or system message.

+6. **Response generation**: The model uses the provided context to generate the final response along with citations.

+## How to structure debugging investigation

+When you see an unfavorable response to a query, it might be the result of outputs from various components not working as expected. You can debug the outputs of each component by using the following steps.

+### Step 1: Check for retrieval problems

+Use the REST API to check if the correct document chunks are present in the retrieved documents. In the API response, check the citations in the `tool` message.

+### Step 2: Check for generation problems

+If the correct document chunks appear in the retrieved documents, you're likely encountering a problem with content generation. Consider using a more powerful model through one of these methods:

+* Upgrade the model. For example, if you're using `gpt-35-turbo`, consider using `gpt-4`.

+* Switch the model version. For example, if you're using `gpt-35-turbo-1106`, consider using `gpt-35-turbo-16k` (0613).

+You can also tune the finer aspects of the response by changing the role information or system message.

+### Step 3: Check the rest of the funnel

+If the correct document chunks don't appear in the retrieved documents, you need to dig farther down the funnel:

+* It's possible that a correct document chunk was retrieved but was filtered out based on strictness. In this case, try reducing the `strictness` parameter.

+* It's possible that a correct document chunk wasn't part of the `topNDocuments` parameter. In this case, increase the parameter.

+* It's possible that your index fields are incorrectly mapped, so retrieval might not work well. This mapping is particularly relevant if you're using a pre-existing data source. (That is, you didn't create the index by using the studio or offline scripts available on [GitHub](https://github.com/microsoft/sample-app-aoai-chatGPT/tree/main/scripts).) For more information on mapping index fields, see the [how-to article](../concepts/use-your-data.md?tabs=ai-search#index-field-mapping).

+* It's possible that the intent generation step isn't working well. In the API response, check the `intents` fields in the `tool` message.

+ Some models don't work well for intent generation. For example, if you're using the `GPT-35-turbo-1106` model version, consider using a later model, such as `gpt-35-turbo` (0125) or `GPT-4-1106-preview`.

+* Do you have semistructured data in your documents, such as numerous tables? There might be an ingestion problem. Your data might need special handling during ingestion.

+ * If the file format is PDF, we offer optimized ingestion for tables by using the offline scripts available on [GitHub](https://github.com/microsoft/sample-app-aoai-chatGPT/tree/main/scripts). To use the scripts, you need to have a [Document Intelligence](../../document-intelligence/overview.md) resource and use the [layout model](../../document-intelligence/concept-layout.md).

+

+ * You can adjust your [chunk size](../concepts/use-your-data.md#chunk-size-preview) to make sure your largest table fits within it.

+* Are you converting a semistructured data type, such as JSON or XML, to a PDF document? This conversion might cause an ingestion problem because structured information needs a chunking strategy that's different from purely text content.

+* If none of the preceding items apply, you might be encountering a retrieval problem. Consider using a more powerful `query_type` value. Based on our benchmarking, `semantic` and `vectorSemanticHybrid` are preferred.

+## Common problems

+The following sections list possible solutions to problems that you might encounter when you're developing a solution by using Azure OpenAI Service On Your Data.

+### The information is correct, but the model responds with "The requested information isn't present in the retrieved documents. Please try a different query or topic."

+See [step 3](#step-3-check-the-rest-of-the-funnel) in the preceding debugging process.

+### A response is from your data, but it isn't relevant or correct in the context of the question

+See the preceding debugging process, starting at [step 1](#step-1-check-for-retrieval-problems).

+### The model isn't following the role information or system message

+* Make sure that instructions in the role information are consistent with the [Responsible AI guidelines](/legal/cognitive-services/openai/overview?context=%2Fazure%2Fai-services%2Fopenai%2Fcontext%2Fcontext). The model likely won't follow role information if it contradicts those guidelines.

+* Ensure that your role information follows the [established limits](../concepts/use-your-data.md#token-usage-estimation-for-azure-openai-on-your-data) for it. Each model has an implicit token limit for the role information. Beyond that limit, the information is truncated.

+* Use the prompt engineering technique of repeating an important instruction at the end of the prompt. Putting a double asterisk (`**`) on both sides of the important information can also help.

+* Upgrade to a newer GPT-4 model, because it's likely to follow your instructions better than GPT-3.5.

+### Responses have inconsistencies

+* Ensure that you're using a low `temperature` value. We recommend setting it to `0`.

+* By using the REST API, check if the generated search intents are the same both times. If the intents are different, try a more powerful model such as GPT-4 to see if the chosen model affects the problem. If the intents are the same or similar, try reducing `strictness` or increasing `topNDocuments`.

+> [!NOTE]

+> Although the question is the same, the conversation history is added to the context and affects how the model responds to the same question over a long session.

+### Intents are empty or wrong

+* See [Step 3](#step-3-check-the-rest-of-the-funnel) in the preceding debugging process.

+* If intents are irrelevant, the problem might be that the intent generation step lacks context. Intent generation considers only the user question and conversation history. It doesn't consider the role information or the document chunks. You might consider adding a prefix to each user question with a short context string to help the intent generation step.

+### You set inScope=true or selected the checkbox for restricting responses to data, but the model still responds to out-of-domain questions

+* Consider increasing `strictness`.

+* Add the following instruction in your role information or system message:

+ `You are also allowed to respond to questions based on the retrieved documents.`

+* Set the `inScope` parameter to `true`. The parameter isn't a hard switch, but setting it to `true` encourages the model to stay restricted.

+### A response is correct but is occasionally missing document references or citations

+* Consider upgrading to a GPT-4 model if you're already not using it. GPT-4 is generally more consistent with citation generation.

+* Try to emphasize citation generation in the response by adding `You must generate citation based on the retrieved documents in the response` in the role information.

+* Try adding a prefix in the user query `You must generate citation to the retrieved documents in the response to the user question \n User Question: {actual user question}`.

+ Title: 'Use the Azure OpenAI web app'

+Along with Azure OpenAI Studio, APIs, and SDKs, you can use the available standalone web app to interact with Azure OpenAI Service models by using a graphical user interface. You can deploy the app by using either Azure OpenAI Studio or a [manual deployment](https://github.com/microsoft/sample-app-aoai-chatGPT).

+

+- Publishing creates an Azure App Service instance in your subscription. It might incur costs depending on the [pricing plan](https://azure.microsoft.com/pricing/details/app-service/windows/) that you select. When you're done with your app, you can delete it from the Azure portal.

+- GPT-4 Turbo with Vision models are not supported.

+- By default, the app is deployed with the Microsoft identity provider already configured. The identity provider restricts access to the app to members of your Azure tenant. To add or modify authentication:

+ 1. Go to the [Azure portal](https://portal.azure.com/#home) and search for the app name that you specified during publishing. Select the web app, and then select **Authentication** on the left menu. Then select **Add identity provider**.

+ :::image type="content" source="../media/quickstarts/web-app-authentication.png" alt-text="Screenshot of the authentication pane in the Azure portal." lightbox="../media/quickstarts/web-app-authentication.png":::

+ 1. Select Microsoft as the identity provider. The default settings on this page restrict the app to your tenant only, so you don't need to change anything else here. Select **Add**.

+ Now users will be asked to sign in with their Microsoft Entra account to access your app. You can follow a similar process to add another identity provider if you prefer. The app doesn't use the user's sign-in information in any way other than verifying that the user is a member of your tenant.

+You can customize the app's front-end and back-end logic. The app provides several [environment variables](https://github.com/microsoft/sample-app-aoai-chatGPT#common-customization-scenarios-eg-updating-the-default-chat-logo-and-headers) for common customization scenarios such as changing the icon in the app.

+When you're customizing the app, we recommend:

+- Resetting the chat session (clear chat) if users change any settings. Notify the users that their chat history will be lost.

+- Clearly communicating how each setting that you implement will affect the user experience.

+- Updating the app settings for each of your deployed apps to use new API keys after you rotate keys for your Azure OpenAI or Azure AI Search resource.

+Sample source code for the web app is available on [GitHub](https://github.com/microsoft/sample-app-aoai-chatGPT). Source code is provided "as is" and as a sample only. Customers are responsible for all customization and implementation of their web apps.

+> As of February 1, 2024, the web app requires the app startup command to be set to `python3 -m gunicorn app:app`. When you're updating an app that was published before February 1, 2024, you need to manually add the startup command from the **App Service Configuration** page.

+We recommend pulling changes from the `main` branch for the web app's source code frequently to ensure that you have the latest bug fixes, API version, and improvements. Additionally, the web app must be synchronized every time the API version that you're using is [retired](../api-version-deprecation.md). Consider selecting either the **Watch** or the **Star** button on the web app's [GitHub repo](https://github.com/microsoft/sample-app-aoai-chatGPT) to be notified about changes and updates to the source code.

+If you haven't customized the web app, you can use these steps to synchronize it:

+1. Go to your web app in the [Azure portal](https://portal.azure.com/).

+1. On the left menu, under **Deployment**, select **Deployment Center**.

+1. Select **Sync** at the top of the pane, and confirm that the app will be redeployed.

+ :::image type="content" source="../media/use-your-data/sync-app.png" alt-text="A screenshot of the web app synchronization button on the Azure portal." lightbox="../media/use-your-data/sync-app.png":::

+If you customized or changed the app's source code, you need to update your app's source code manually and redeploy it:

+- If your app is hosted on GitHub, push your code changes to your repo, and then use the preceding synchronization steps.

+- If you're redeploying the app manually (for example, by using the Azure CLI), follow the steps for your deployment strategy.

+You can turn on chat history for your users of the web app. When you turn on the feature, users have access to their individual previous queries and responses.

+To turn on chat history, deploy or redeploy your model as a web app by using [Azure OpenAI Studio](https://oai.azure.com/portal) and select **Enable chat history in the web app**.

+> Turning on chat history creates an [Azure Cosmos DB](/azure/cosmos-db/introduction) instance in your resource group, and it incurs [additional charges](https://azure.microsoft.com/pricing/details/cosmos-db/autoscale-provisioned/) for the storage that you use.

+After you turn on chat history, your users can show and hide it in the upper-right corner of the app. When users show chat history, they can rename or delete conversations. Because the users are signed in to the app, conversations are automatically ordered from newest to oldest. Conversations are named based on the first query in the conversation.

+Deleting your web app does not delete your Cosmos DB instance automatically. To delete your Cosmos DB instance along with all stored chats, you need to go to the associated resource in the [Azure portal](https://portal.azure.com) and delete it. If you delete the Cosmos DB resource but keep the chat history option turned on in the studio, your users are notified of a connection error but can continue to use the web app without access to the chat history.

+While innovation delivered with this release cadence provides huge benefits to you, it challenges you to keep up to date with Kubernetes releases, which can be made more difficult based on the number of AKS clusters you have to maintain.

+After approximately one year, the Kubernetes version exits Community support and your AKS clusters are now at risk as bug fixes and security updates become unavailable.

+LTS intends to give you an extended period of time to plan and test for upgrades over a two-year period from the General Availability of the designated Kubernetes version.

+See the following table for a list of add-ons and features that aren't supported and the reason why.

+>You can't move your cluster to long-term support if any of these add-ons or features are enabled.

+> The next Long Term Support Version after 1.27 is to be determined. However Customers will get a minimum 6 months of overlap between 1.27 LTS and the next LTS version to plan upgrades.

+## Frequently asked questions

+### Community support for AKS 1.27 ends expires in July 2024. Can I create a new AKS cluster with version 1.27 after that date?

+Yes, as long as LTS is enabled on the cluster, you can create a new AKS cluster with version 1.27 after the community support window has ended.

+### Can I enable and disable LTS on AKS 1.27 after the end of community support?

+You can enable the LTS support plan on AKS 1.27 after the end of community support. However, you can't disable LTS on AKS 1.27 after the end of community support.

+### I have a cluster running on version 1.27. Does it mean it is automatically in LTS?

+No, you need to explicitly enable LTS on the cluster to receive LTS support. Enabling LTS also requires being on the Premium tier.

+### What is the pricing model for LTS?

+LTS is available on the Premium tier, please refer to the [Premium tier pricing](https://azure.microsoft.com/pricing/details/kubernetes-service/) for more information.

+description: Learn how to upgrade the OS version for Windows workloads on Azure Kubernetes Service (AKS).

+# Upgrade the OS version for your Azure Kubernetes Service (AKS) Windows workloads

+When upgrading the OS version of a running Windows workload on Azure Kubernetes Service (AKS), you need to deploy a new node pool to ensure the Windows versions match on each node pool. This article describes the steps to upgrade the OS version for Windows workloads on AKS. While this example focuses on the upgrade from Windows Server 2019 to Windows Server 2022, the same process can be followed to upgrade from any Windows Server version to another.

+## Windows Server OS version support

+When a new version of the Windows Server operating system is released, AKS is committed to supporting it and recommending you upgrade to the latest version to take advantage of the fixes, improvements, and new functionality. AKS provides a five-year support lifecycle for every Windows Server version, starting with Windows Server 2022. During this period, AKS will release a new version that supports a newer version of Windows Server OS for you to upgrade to.

+> [!NOTE]

+> - Windows Server 2019 is being retired after Kubernetes version 1.32 reaches end of life (EOL). For more information, see [AKS release notes][aks-release-notes].

+> - Windows Server 2022 is being retired after Kubernetes version 1.34 reaches its end of life (EOL). For more information, see [AKS release notes][aks-release-notes].

+## Limitations

+Windows Server 2019 and Windows Server 2022 can't coexist on the same node pool on AKS. You need to create a new node pool to host the new OS version. It's important that you match the permissions and access of the previous node pool to the new one.

+## Before you begin

+- Update the `FROM` statement in your Dockerfile to the new OS version.

+- Check your application and verify the container app works on the new OS version.

+- Deploy the verified container app on AKS to a development or testing environment.

+- Take note of the new image name or tag for use in this article.

+> [!NOTE]

+> To learn how to build a Dockerfile for Windows workloads, see [Dockerfile on Windows](/virtualization/windowscontainers/manage-docker/manage-windows-dockerfile) and [Optimize Windows Dockerfiles](/virtualization/windowscontainers/manage-docker/optimize-windows-dockerfile).

+## Add a Windows Server 2022 node pool to an existing cluster

+- [Add a Windows Server 2022 node pool](./learn/quick-windows-container-deploy-cli.md) to an existing cluster.

+## Update the YAML file

+Node Selector is the most common and recommended option for placement of Windows pods on Windows nodes.

+1. Add Node Selector to your YAML file by adding the following annotation:

+ ```yaml

+ nodeSelector:

+ "kubernetes.io/os": windows

+ ```

+ The annotation finds any available Windows node and places the pod on that node (following all other scheduling rules). When upgrading from Windows Server 2019 to Windows Server 2022, you need to enforce the placement on a Windows node and a node running the latest OS version. To accomplish this, one option is to use a different annotation:

+ ```yaml

+ nodeSelector:

+ "kubernetes.azure.com/os-sku": Windows2022

+ ```

+2. Once you update the `nodeSelector` in the YAML file, you also need to update the container image you want to use. You can get this information from the previous step in which you created a new version of the containerized application by changing the `FROM` statement on your Dockerfile.

+> [!NOTE]

+> You should use the same YAML file you used to initially deploy the application. This ensures that no other configuration changes besides the `nodeSelector` and container image.

+## Apply the updated YAML file to the existing workload

+1. View the nodes on your cluster using the `kubectl get nodes` command.

+ ```bash

+ kubectl get nodes -o wide

+ ```

+ The following example output shows all nodes on the cluster, including the new node pool you created and the existing node pools:

+ ```output

+ NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME

+ aks-agentpool-18877473-vmss000000 Ready agent 5h40m v1.23.8 10.240.0.4 <none> Ubuntu 18.04.6 LTS 5.4.0-1085-azure containerd://1.5.11+azure-2

+ ```

+2. Apply the updated YAML file to the existing workload using the `kubectl apply` command and specify the name of the YAML file.

+ ```bash

+ kubectl apply -f <filename>

+ ```

+ The following example output shows a *configured* status for the deployment:

+ ```output

+ deployment.apps/sample configured

+ service/sample unchanged

+ ```

+ At this point, AKS starts the process of terminating the existing pods and deploying new pods to the Windows Server 2022 nodes.

+3. Check the status of the deployment using the `kubectl get pods` command.

+ ```bash

+ kubectl get pods -o wide

+ ```

+ The following example output shows the pods in the `default` namespace:

+ ```output

+ NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES

+ sample-7794bfcc4c-k62cq 1/1 Running 0 2m49s 10.240.0.238 akspoolws000000 <none> <none>

+ sample-7794bfcc4c-sh78c 1/1 Running 0 2m49s 10.240.0.228 akspoolws000000 <none> <none>

+ ```

+## Security and authentication considerations

+If you're using Group Managed Service Accounts (gMSA), you need to update the Managed Identity configuration for the new node pool. gMSA uses a secret (user account and password) so the node that runs the Windows pod can authenticate the container against Microsoft Entra ID. To access that secret on Azure Key Vault, the node uses a Managed Identity that allows the node to access the resource. Since Managed Identities are configured per node pool, and the pod now resides on a new node pool, you need to update that configuration. For more information, see [Enable Group Managed Service Accounts (GMSA) for your Windows Server nodes on your Azure Kubernetes Service (AKS) cluster](./use-group-managed-service-accounts.md).

+The same principle applies to Managed Identities for any other pod or node pool when accessing other Azure resources. You need to update any access that Managed Identity provides to reflect the new node pool. To view update and sign-in activities, see [How to view Managed Identity activity](../active-directory/managed-identities-azure-resources/how-to-view-managed-identity-activity.md).

+ Title: Use Windows Annual Channel for Containers on Azure Kubernetes Service (AKS)

+description: Learn about Windows Annual Channel for Containers for Windows containers on Azure Kubernetes Service (AKS).

+# Use Windows Annual Channel for Containers on Azure Kubernetes Service (AKS) (Preview)

+AKS supports [Windows Server Annual Channel for Containers](https://techcommunity.microsoft.com/t5/windows-server-news-and-best/windows-server-annual-channel-for-containers/ba-p/3866248) in public preview. Each channel version is released annually and is supported for *two years*. This channel is beneficial if you require increased innovation cycles and portability.

+Windows Annual Channel versions are based on the Kubernetes version of your node pool. To upgrade from one Annual Channel version to the next, you can [upgrade to a Kubernetes version][upgrade-aks-cluster] that supports the next Annual Channel version.

+## Supported Annual Channel releases

+AKS releases support for new releases of Windows Server Annual Channel for Containers in alignment with Kubernetes versions. For the latest updates, see the [AKS release notes][release-notes]. The following table provides an estimated release schedule for upcoming Annual Channel releases:

+| K8s version | Annual Channel (host) version | Container image supported | End of support date |

+|--|-|-|-|

+| 1.28 | 23H2 (preview only) | Windows Server 2022 | End of 1.30 support |

+| 1.31 | 24H2 | Windows Server 2022 & Windows Server 2025 | End of 1.34 support |

+| 1.35 | 25H2 | Windows Server 2025 | End of 1.38 support |

+## Windows Annual Channel vs. Long Term Servicing Channel Releases (LTSC)

+AKS supports Long Term Servicing Channel Releases (LTSC), including Windows Server 2022 and Windows Server 2019. These come from a different release channel than Windows Server Annual Channel for Containers. To view our current recommendations, see the [Windows best practices documentation][windows-best-practices].

+> [!NOTE]

+> Windows Server 2019 will retire after Kubernetes version 1.32 reaches end of life, and Windows Server 2022 will retire after Kubernetes version 1.34 reaches end of life. For more information, see the [AKS release notes][release-notes].

+The following table compares Windows Annual Channel and Long Term Servicing Channel releases:

+| Channel | Support | Upgrades |

+|||-|

+| Long Term Servicing Channel (LTSC) | LTSC channels are released every three years and are supported for five years. This channel is recommended for customers using Long Term Support. | To upgrade from one release to the next, you need to migrate your node pools to a new OS SKU option and rebuild your container images with the new OS version. |

+| Annual Channel for Containers | Annual Channel releases occur annually and are supported for two years. | To upgrade to the latest release, you can upgrade the Kubernetes version of your node pool. |

+## Before you begin

+* You need the Azure CLI version 2.56.0 or later installed and configured to set `os-sku` to `WindowsAnnual` with the `az aks nodepool add` command. Run `az --version` to find the version. If you need to install or upgrade, see [Install Azure CLI][install-azure-cli].

+### Limitations

+* Windows Annual Channel doesn't support Azure Network Policy Manager (NPM).

+### Install the `aks-preview` Azure CLI extension

+* Register or update the aks-preview extension using the [`az extension add`][az-extension-add] or [`az extension update`][az-extension-update] command.

+ ```azurecli-interactive

+ # Register the aks-preview extension

+ az extension add --name aks-preview

+ # Update the aks-preview extension

+ az extension update --name aks-preview

+ ```

+### Register the `AKSWindowsAnnualPreview` feature flag

+1. Register the `AKSWindowsAnnualPreview` feature flag using the [`az feature register`][az-feature-register] command.

+ ```azurecli-interactive

+ az feature register --namespace "Microsoft.ContainerService" --name "WindowsAnnualPreview"

+ ```

+ It takes a few minutes for the status to show *Registered*.

+2. Verify the registration status using the [`az feature show`][az-feature-show] command.

+ ```azurecli-interactive

+ az feature show --namespace "Microsoft.ContainerService" --name "AKSWindowsAnnualPreview"

+ ```

+3. When the status reflects *Registered*, refresh the registration of the *Microsoft.ContainerService* resource provider using the [`az provider register`][az-provider-register] command.

+ ```azurecli-interactive

+ az provider register --namespace Microsoft.ContainerService

+ ```

+## Use Windows Annual Channel for Containers on AKS

+To use Windows Annual Channel on AKS, specify the following parameters:

+* `os-type` set to `Windows`

+* `os-sku` set to `WindowsAnnual`

+Windows Annual Channel versions are based on the Kubernetes version of your node pool. To check which release you'll get based on the Kubernetes version of your node pool, see the [supported Annual Channel releases](#supported-annual-channel-releases).

+### Create a new Windows Annual Channel node pool

+#### [Azure CLI](#tab/azure-cli)

+* Create a Windows Annual Channel node pool using the [`az aks nodepool add`][az-aks-nodepool-add] command. The following example creates a Windows Annual Channel node pool with the 23H2 release:

+ ```azurecli-interactive

+ az aks nodepool add \

+ --resource-group $RESOURCE_GROUP_NAME \

+ --cluster-name $CLUSTER_NAME \

+ --os-type Windows \

+ --os-sku WindowsAnnual \

+ --kubernetes-version 1.29

+ --name $NODE_POOL_NAME \

+ --node-count 1

+ ```

+ > [!NOTE]

+ > If you don't specify the Kubernetes version during node pool creation, AKS uses the same Kubernetes version as your cluster.

+#### [Azure PowerShell](#tab/azure-powershell)

+* Create a Windows Annual Channel node pool using the [`New-AzAksNodePool`][new-azaksnodepool] cmdlet.

+ ```azurepowershell

+ New-AzAksNodePool -ResourceGroupName $RESOURCE_GROUP_NAME `

+ -ClusterName $CLUSTER_NAME `

+ -VmSetType VirtualMachineScaleSets `

+ -OsType Windows `

+ -OsSKU WindowsAnnual `

+ -Name $NODE_POOL_NAME

+ ```

+### Verify Windows Annual Channel node pool creation

+* Verify Windows Annual Channel node pool creation by checking the OS SKU of your node pool using `kubectl describe node` command.

+ ```bash

+ kubectl describe node $NODE_POOL_NAME

+ ```

+ If you successfully created a Windows Annual Channel node pool, you should see the following output:

+ ```output

+ Name: npwin

+ Roles: agent

+ Labels: agentpool=npwin

+ ...

+ kubernetes.azure.com/os=windows

+ ...

+ kubernetes.azure.com/node-image-version=AKSWindows-23H2-gen2

+ ...

+ kubernetes.azure.com/os-sku=WindowsAnnual

+ ```

+### Upgrade an existing node pool to Windows Annual Channel

+You can upgrade an existing node pool from an LTSC release to Windows Annual Channel by following the guidance in [Upgrade the OS version for your Azure Kubernetes Service (AKS) Windows workloads][upgrade-windows-os].

+To upgrade from one Annual Channel version to the next, you can [upgrade to a Kubernetes version][upgrade-aks-cluster] that supports the next Annual Channel version.

+> Windows Server 2022 provides improved security and performance and is the recommended OS for Windows node pools on AKS. AKS uses Windows Server 2022 as the host OS version and only supports process isolation.

+AKS supports two options for the Windows Server operating system: Long Term Servicing Channel Releases (LTSC) and Windows Server Annual Channel for Containers.

+1. AKS supports Long Term Servicing Channel Releases (LTSC), including Windows Server 2022 and Windows Server 2019. This channel is released every three years and is supported for five years. Customers using Long Term Support (LTS) should use Windows Server 2022.

+ AKS uses Windows Server 2019 and Windows Server 2022 as the host OS versions and only supports process isolation. AKS doesn't support container images built by other versions of Windows Server. For more information, see [Windows container version compatibility](/virtualization/windowscontainers/deploy-containers/version-compatibility).

+ Windows Server 2022 is the default OS for Kubernetes version 1.25 and later. Windows Server 2019 will retire after Kubernetes version 1.32 reaches end of life. Windows Server 2022 will retire after Kubernetes version 1.34 reaches its end of life. For more information, see [AKS release notes][aks-release-notes]. To stay up to date on the latest Windows Server OS versions and learn more about our roadmap of what's planned for support on AKS, see our [AKS public roadmap](https://github.com/azure/aks/projects/1).

+2. AKS supports [Windows Server Annual Channel for Containers](https://techcommunity.microsoft.com/t5/windows-server-news-and-best/windows-server-annual-channel-for-containers/ba-p/3866248) (preview). This channel is released annually and is supported for 2 years. This channel is beneficial for customers requiring increased innovation cycles and portability. The portability functionality enables the Windows Server 2022-based container image OS to run on newer versions of Windows Server host OS, such as the new annual channel release.

+ Windows Annual Channel versions are based on the Kubernetes version of your node pool. To upgrade from one Annual Channel version to the next, [upgrade to a Kubernetes version](./upgrade-aks-cluster.md) that supports the next Annual Channel version.

+description: Shows you how to connect to other Azure services such as a database, storage, or another app. This overview recommends the more secure method for connecting.

+#customer intent: As a developer, I want to learn how to securely connect to Azure resources from Azure App Service so that I can protect sensitive data and ensure secure communication.

+# Secure connectivity to Azure services and databases from Azure App Service

+Your app service might need to connect to other Azure services such as a database, storage, or another app. This overview recommends different methods for connecting and when to use them.

+Today, the decision for a connectivity approach is closely related to secrets management. The common pattern of using connection secrets in connection strings, such as username and password, secret key, etc. is no longer considered the most secure approach for connectivity. The risk is even higher today because threat actors regularly crawl public GitHub repositories for accidentally committed connection secrets. For cloud applications, the best secrets management is to have no secrets at all. When you migrate to Azure App Service, your app might start with secrets-based connectivity, and App Service lets you keep secrets securely. However, Azure can help secure your app's back-end connectivity through Microsoft Entra authentication, which eliminates secrets altogether in your app.

+|[Connect with an app identity](#connect-with-an-app-identity)|* You want to remove credentials, keys, or secrets completely from your application.<br/>* The downstream Azure service supports Microsoft Entra authentication, such as Microsoft Graph.<br/>* The downstream resource doesn't need to know the current signed-in user or doesn't need granular authorization of the current signed-in user.|

+|[Connect on behalf of the signed-in user](#connect-on-behalf-of-the-signed-in-user)| * The app must access a downstream resource on behalf of the signed-in user.<br/>* The downstream Azure service supports Microsoft Entra authentication, such as Microsoft Graph.<br/>* The downstream resource must perform granular authorization of the current signed-in user.|

+|[Connect using secrets](#connect-using-secrets)|* The downstream resource requires connection secrets.<br/>* Your app connects to non-Azure services, such as an on-premises database server.<br/>* The downstream Azure service doesn't support Microsoft Entra authentication yet.|

+## Connect with an app identity

+If your app already uses a single set of credentials to access a downstream Azure service, you can quickly convert the connection to use an app identity instead. A [managed identity](overview-managed-identity.md) from Microsoft Entra ID lets App Service access resources without secrets, and you can manage its access through role-based access control (RBAC). A managed identity can connect to any Azure resource that supports Microsoft Entra authentication, and the authentication takes place with short-lived tokens.

+The following image demonstrates the following an App Service connecting to other Azure

+* A: User visits Azure app service website.

+* B: Securely **connect from** App Service **to** another Azure service using a managed identity.

+* C: Securely **connect from** App Service **to** Microsoft Graph using a managed identity.

+- [Tutorial: Connect to a PostgreSQL Database from Java Tomcat App Service without secrets using a managed identity](tutorial-java-tomcat-connect-managed-identity-postgresql-database.md)

+## Connect on behalf of the signed-in user

+Your app might need to connect to a downstream service on behalf of the signed-in user. App Service lets you easily authenticate users using the most common identity providers (see [Authentication and authorization in Azure App Service and Azure Functions](overview-authentication-authorization.md)). If you use the Microsoft provider (Microsoft Entra authentication), you can then flow the signed-in user to any downstream service. For example:

+- Run a database query that returns confidential data that the signed-in user is authorized to read.

+- Retrieve personal data or take actions as the signed-in user in Microsoft Graph.

+The following image demonstrates an application securely accessing an SQL database on behalf of the signed-in user.

+Some common scenarios are:

+- [Connect to Microsoft Graph on behalf of the user](scenario-secure-app-access-microsoft-graph-as-user.md)

+- [Connect to an SQL database on behalf the user](tutorial-connect-app-access-sql-database-as-user-dotnet.md)

+- [Connect to another App Service app on behalf of the user](tutorial-auth-aad.md)

+- [Flow the signed-in user through multiple layers of downstream services](tutorial-connect-app-app-graph-javascript.md)

+## Connect using secrets

+There are two recommended ways to use secrets in your app: using secrets stored in Azure Key Vault or secrets in App Service app settings.

+### Use secrets from Key Vault

+[Azure Key Vault](app-service-key-vault-references.md) can be used to securely store secrets and keys, monitor access and use of secrets, and simplify administration of application secrets. If the downstream service doesn't support Microsoft Entra authentication or requires a connection string or key, use Key Vault to store your secrets and connect your app to Key Vault with a managed identity and retrieve the secrets. Your app can access they key vault secrets as [Key Vault references](app-service-key-vault-references.md) in the app settings.

+Benefits of managed identities integrated with Key Vault include:

+- Access to the key vault secret is restricted to the app.

+- App contributors, such as administrators, might have complete control of the App Service resources, and at the same time have no access to the key vault secrets.

+- No code change is required if your application code already accesses connection secrets with app settings.

+- Key Vault provides monitoring and auditing of who accessed secrets.

+- Rotation of key vault secrets requires no changes in App Service.

+The following image demonstrates App Service connecting to Key Vault using a managed identity and then accessing an Azure service using secrets stored in Key Vault:

+### Use secrets in app settings

+For apps that connect to services using secrets (such as usernames, passwords, and API keys), App Service can store them securely in [app settings](configure-common.md). These secrets are injected into your application code as environment variables at app startup. App settings are always encrypted when stored (encrypted-at-rest). For more advanced secrets management, such as secrets rotation, access policies, and audit history, try [using Key Vault](#use-secrets-from-key-vault).

+> * Use passwordless SQL connectivity by using a managed identity

+> [!TIP]

+> The default SQL database connection string uses SQL authentication. For more secure, passwordless authentication, see [How do I change the SQL Database connection to use a managed identity instead?](#how-do-i-change-the-sql-database-connection-to-use-a-managed-identity-instead)

+> The default SQL database connection string uses SQL authentication. For more secure, passwordless authentication, see [How do I change the SQL Database connection to use a managed identity instead?](#how-do-i-change-the-sql-database-connection-to-use-a-managed-identity-instead)

+The sample application includes standard logging statements to demonstrate this capability, as shown in the following snippet:

+- [How do I change the SQL Database connection to use a managed identity instead?](#how-do-i-change-the-sql-database-connection-to-use-a-managed-identity-instead)

+### How do I change the SQL Database connection to use a managed identity instead?

+The default connection string to the SQL database is managed by Service Connector, with the name *defaultConnector*, and it uses SQL authentication. To replace it with a connection that uses a managed identity, run the following commands in the [cloud shell](https://shell.azure.com) after replacing the placeholders:

+```azurecli-interactive

+az extension add --name serviceconnector-passwordless --upgrade

+az sql server update --enable-public-network true

+az webapp connection delete sql --connection defaultConnector --resource-group <group-name> --name <app-name>

+az webapp connection create sql --connection defaultConnector --resource-group <group-name> --name <app-name> --target-resource-group <group-name> --server <database-server-name> --database <database-name> --client-type dotnet --system-identity --config-connstr true

+az sql server update --enable-public-network false

+```

+By default, the command `az webapp connection create sql --client-type dotnet --system-identity --config-connstr` does the following:

+- Sets your user as the Microsoft Entra ID administrator of the SQL database server.

+- Create a system-assigned managed identity and grants it access to the database.

+- Generates a passwordless connection string called `AZURE_SQL_CONNECTIONGSTRING`, which your app is already using at the end of the tutorial.

+Your app should now have connectivity to the SQL database. For more information, see [Tutorial: Connect to Azure databases from App Service without secrets using a managed identity](tutorial-connect-msi-azure-database.md).

+> [!TIP]

+> **Don't want to enable public network connection?** You can skip `az sql server update --enable-public-network true` by running the commands from an [Azure cloud shell that's integrated with your virtual network](../cloud-shell/vnet/deployment.md) if you have the **Owner** role assignment on your subscription.

+>

+> To grant the identity the required access to the database that's secured by the virtual network, `az webapp connection create sql` needs direct connectivity with Entra ID authentication to the database server. By default, the Azure cloud shell doesn't have this access to the network-secured database.

+1. Navigate to your list of virtual machines and refresh the page every few seconds. Observe that the action for each VM happens in parallel. Without the `-Parallel` keyword, the actions would have performed sequentially. While the VMs will start in parallel, each VM may reach the **Running** phase at slightly different times based on the characteristics of each VM.

+ ```sql

+ # AutomationAccount - replace with your Automation account's name

+ # ObjectID - replace with object (principal) ID for your system managed identity principal from step 1.

+ CREATE USER "AutomationAccount" FROM EXTERNAL PROVIDER WITH OBJECT_ID = `ObjectID`

+ EXEC sp_addrolemember `db_owner`, "AutomationAccount"

+ ```

+> According to [this](/azure/devops/organizations/accounts/change-application-access-policies#application-connection-policies) Azure DevOps documentation, **Third-party application access via OAuth** policy is defaulted to **off** for all new organizations. So if you try to configure source control in Azure Automation with **Azure DevOps (Git)** as source control type without enabling **Third-party application access via OAuth** under Policies tile of Organization Settings in Azure DevOps then you might get **SourceControl securityToken is invalid** error. Hence to avoid this error, make sure you first enable **Third-party application access via OAuth** under Policies tile of Organization Settings in Azure DevOps.

+Capacity pools must be at least 1 TiB and can be increased or decreased in 1-TiB intervals. Capacity pools contain volumes that range in size from a minimum of 100 GiB to a maximum of 100 TiB for regular volumes and up to 500 TiB for [large volumes](azure-netapp-files-understand-storage-hierarchy.md#large-volumes). Volumes are assigned quotas that are subtracted from the capacity poolΓÇÖs provisioned size. For an active volume, capacity consumption against the quota is based on logical (effective) capacity, being active filesystem data or snapshot data. See [How Azure NetApp Files snapshots work](snapshots-introduction.md) for details.

+| Maximum size of a single capacity pool | 2048 TiB | Yes |

+You can [submit a support request](azure-netapp-files-resource-limits.md#request-limit-increase) for an increase of a regional capacity quota without incurring extra cost. The support request you submit is sent to the Azure capacity management team for processing. You typically receive a response within two business days. The Azure capacity management team might contact you if you have a large request.

+A regional capacity quota increase doesn't incur a billing increase. Billing is still based on the provisioned capacity pools.

+For example, if you currently have 25 TiB of provisioned capacity, you can request a quota increase to 35 TiB. Within two business days, your quota increase is applied to the requested region. When the quota increase is applied, you still pay for only the current provisioned capacity (25 TiB). But when you actually provision the additional 10 TiB, you're billed for 35 TiB.

+To understand minimum and maximum capacity pool sizes, see [resource limits](azure-netapp-files-resource-limits.md#resource-limits) for Azure NetApp Files.

+>[!Note]

+>If there're any updates to the current Key Vault details in the **Encryption Settings** with new key vault information, the managed identity used for **Encryption Settings** must retain access to the original Key Vault, with *Get* and *Unwrap* permissions, and the key should be in *Enabled* state. This access is necessary to execute the *key rotation* from the *previous* to the *new* key.

+2. For **Encryption Settings**, select **Update**.

+This section lists the various troubleshooting scenarios that you might encounter for Backup vault encryption.

+### Backup, restore, and background operations failures

+**Causes**:

+- **Cause 1**: If there's an issue with your **Backup vault Encryption Settings**, such as you have removed Key Vault permissions from Encryption SettingsΓÇÖ managed identity, disabled system-assigned identity, or detached/deleted the managed identity from the Backup vault that you're using for encryption settings, then *backup* and *restore* jobs fail.

+- **Cause 2**: Tiering of restore points and restore-points expiration jobs will fail without showing errors in the Azure portal or other interfaces (for example, REST API or CLI). These operations will continue to fail and incur costs.

+**Recommended actions**:

+- **Recommendation 1**: Restore the permissions, update the managed identity details that have access to the key vault.

+- **Recommendation 2**: Restore the required encryption settings to the Backup vault.

+- The Key Vault and key don't exist, and aren't reachable to the Azure Backup service via network settings.

+## Validate error codes

+Azure Backup validates the selected *Azure Key Vault* when CMK is applied on the backup vault. If the Key Vault doesn't have the required configuration settings (**Soft Delete Enabled** and **Purge Protection Enabled**), the following error-codes appear:

+### UserErrorCMKPurgeProtectionNotEnabledOnKeyVault

+**Error code**: `UserErrorCMKPurgeProtectionNotEnabledOnKeyVault`

+**Cause**: Soft delete isn't enabled on the Key Vault.

+**Recommended action**: Enable soft delete on the Key Vault, and then retry the operation.

+### UserErrorCMKSoftDeleteNotEnabledOnKeyVault

+**Error code**: `UserErrorCMKSoftDeleteNotEnabledOnKeyVault`

+**Cause**: Purge Protection isn't enabled on the Key Vault.

+**Recommended action**: Enable Purge Protection on the Key Vault, and then retry the operation.

+Azure Cosmos DB distributes your data across logical and physical partitions based on your partition keys to support horizontal scaling. By using hierarchical partition keys (also called *subpartitoning*), you can configure up to a three-level hierarchy for your partition keys to further optimize data distribution and for a higher level of scaling.

+If you use synthetic keys today, have scenarios in which partition keys can exceed 20 GB of data, or would like to ensure that each tenant's document maps to its own logical partition, subpartitioning can help. If you use this feature, logical partition key prefixes can exceed 20 GB and 10,000 request units per second (RU/s). Queries by prefix are efficiently routed to the subset of partitions that hold the data.

+## Choosing your hierarchical partition keys

+If you have multitenant applications and currently isolate tenants by partition key, hierarchical partitions might benefit you. Hierarchical partitions allow you to scale beyond the logical partition key limit of 20 GB, and are a good solution if you'd like to ensure each of your tenants' documents can scale infinitely. If your current partition key or if a single partition key is frequently reaching 20 GB, hierarchical partitions are a great choice for your workload.

+However, depending on the nature of your workload and how cardinal your first level key is, there can be some tradeoffs which we cover in depth in our hierarchical partition scenarios page.

+When you choose each level of your hierarchical partition key, it's important to keep the following general partitioning concepts in mind and understand how each one can affect your workload:

+- For **all** containers, **each level** of the full path (starting with the **first level**) of your hierarchical partition key should:

+ - **Have a high cardinality**. The first, second, and third (if applicable) keys of the hierarchical partition should all have a wide range of possible values.

+

+ - Having low cardinality at the first level of the hierarchical partition key will limit all of your write operations at the time of ingestion to just one physical partition until it reaches 50 GB and splits into two physical partitions. For example, suppose your first level key is on `TenantId` and only have 5 unique tenants. Each of these tenants' operations will be scoped to just one physical partition, limiting your throughput consumption to just what is on that one physical partition. This is because hierarchical partitions optimize for all documents with the same first-level key to be colloacted on the same physical partition to avoid full-fanout queries.

+ - While this may be okay for workloads where we do a one-time ingest of all our tenants' data and the following operations are primarily read-heavy afterwards, this can be unideal for workloads where your business requirements involve ingestion of data within a specific time. For example, if you have strict business requirements to avoid latencies, the maximum throughput your workload can theoretically achieve to ingest data is number of physical partitions * 10k. If your top-level key has low cardinality, your number of physical partitions will likely be 1, unless there is sufficient data for the level 1 key for it to be spread across multiple partitions after splits which can take between 4-6 hours to complete.

+

+ - **Spread request unit (RU) consumption and data storage evenly across all logical partitions**. This spread ensures even RU consumption and storage distribution across your physical partitions.

+

+ - If you choose a first level key that seems to have high cardinality like `UserId`, but in practice your workload performs operations on just one specific `UserId`, then you are likely to run into a hot partition as all of your operations will be scoped to just one or few physical partitions.

+

+- **Read-heavy workloads:** We recommend that you choose hierarchical partition keys that appear frequently in your queries.

+ - For example, a workload that frequently runs queries to filter out specific user sessions in a multitenant application can benefit from hierarchical partition keys of `TenantId`, `UserId`, and `SessionId`, in that order. Queries can be efficiently routed to only the relevant physical partitions by including the partition key in the filter predicate. For more information about choosing partition keys for read-heavy workloads, see the [partitioning overview](partitioning-overview.md).

+

+- **Write-heavy workloads:** We recommend using a high cardinal value for the **first-level** of your hierarchical partition key. High cardinality means that the first-level key (and subsequent levels as well) has at least thousands of unique values and more unique values than the number of your physical partitions.

+ - For example, suppose we have a workload that isolates tenants by partition key, and has a few large tenants that are more write-heavy than others. Today, Azure Cosmos DB will stop ingesting data on any partition key value if it exceeds 20 GB of data. In this workload, Microsoft and Contoso are large tenants and we anticipate it growing much faster than our other tenants. To avoid the risk of not being able to ingest data for these tenants, hierarchical partition keys allows us to scale these tenants beyond the 20 GB limit. We can add more levels like UserId and SessionId to ensure higher scalability across tenants.

+ - To ensure that your workload can accommodate writes for all documents with the same first-level key, consider using item ID as a second or third level key.

+

+ - If your first level does not have high cardinality and you are hitting the 20 GB logical partition limit on your partition key today, we suggest using a synthetic partition key instead of a hierarchical partition key.

+

+If your workload has tenants with roughly the same workload patterns, hierarchical partition key can help. With hierarchical partition keys, you can partition first on `TenantId`, and then on `UserId`. If you expect the `TenantId` and `UserId` combination to produce partitions that exceed 20 GB, you can even partition further down to another level, such as on `SessionId`. The overall depth can't exceed three levels. When a physical partition exceeds 50 GB of storage, Azure Cosmos DB automatically splits the physical partition so that roughly half of the data is on one physical partition, and half is on the other. Effectively, subpartitioning means that a single `TenantId` value can exceed 20 GB of data, and it's possible for `TenantId` data to span multiple physical partitions.

+Each *compute* configuration has an IOPS limit that depends on the number of vCores. Make sure you select compute configuration for your cluster to fully utilize IOPS in the selected storage.

+| Storage size | Storage IOPS, up to | Min compute tier | Min vCores |

+|-||||

+| Up to 0.5 TiB | 3,500ΓÇá | M30 | 2 vCores |

+| 1 TiB | 5,000 | M40 | 4 vCores |

+| 2 TiB | 7,500 | M50 | 8 vCores |

+| 4 TiB | 7,500 | M50 | 8 vCores |

+| 8 TiB | 16,000 | M60 | 16 vCores |

+| 16 TiB | 18,000 | M60 | 16 vCores |

+| 32 TiB | 20,000 | M60 | 16 vCores |

+For instance, if you need 8 TiB of storage per shard or more, make sure you select 16 vCores or more for the node's compute configuration. That selection would allow you to maximize IOPS usage provided by the selected storage.

+## Considerations for compute and storage

+### Working set and memory considerations

+In Azure Cosmos DB for MongoDB vCore, *the working set* refers to the portion of your data that is frequently accessed and used by your applications. It includes both the data and the indexes that are regularly read or written to during the application's typical operations. The concept of a working set is important for performance optimization because MongoDB, like many databases, performs best when the working set fits in RAM.

+To define and understand your MongoDB database working set, consider the following components:

+1. **Frequently accessed data**: This data include documents that your application reads or updates regularly.

+1. **Indexes**: Indexes that are used in query operations also form part of the working set because they need to be loaded into memory to ensure fast access.

+1. **Application usage patterns**: Analyzing the usage patterns of your application can help identify which parts of your data are accessed most frequently.

+By keeping the working set in RAM, you can minimize slower disk I/O operations, thereby improving the performance of your MongoDB database. If you find that your working set exceeds the available RAM, you might consider optimizing your data model, adding more RAM, or using sharding to distribute the data across multiple nodes.

+### Choosing optimal configuration for a workload

+Determining the right compute and storage configuration for your Azure Cosmos DB for MongoDB vCore workload involves evaluating several factors related to your application's requirements and usage patterns. The key steps and considerations to determine the optimal configuration include:

+1. **Understand your workload**

+ - **Data volume**: Estimate the total size of your data, including indexes.

+ - **Read/write ratio**: Determine the ratio of read operations to write operations.

+ - **Query patterns**: Analyze the types of queries your application performs. For instance, simple reads, complex aggregations.

+ - **Concurrency**: Assess the number of concurrent operations your database needs to handle.

+2. **Monitor current performance**

+ - **Resource utilization**: Use monitoring tools to track CPU, memory, disk I/O, and network usage before you move your workload to Azure and [monitoring metrics](./how-to-monitor-diagnostics-logs.md) once you start running your MongoDB workload on an Azure Cosmos DB for MongoDB vCore cluster.

+ - **Performance metrics**: Monitor key performance metrics such as latency, throughput, and cache hit ratios.

+ - **Bottlenecks**: Identify any existing performance bottlenecks, such as high CPU usage, memory pressure, or slow disk I/O.

+3. **Estimate resource requirements**

+ - **Memory**: Ensure that your [working set](#working-set-and-memory-considerations) (frequently accessed data and indexes) fits into RAM. If your working set size exceeds available memory, consider adding more RAM or optimizing your data model.

+ - **CPU**: Choose a CPU configuration that can handle your query load and concurrency requirements. CPU-intensive workloads may require more cores. Use 'CPU percent' metric with 'Max' aggregation on your Azure Cosmos DB for MongoDB vCore cluster to see historical compute usage patterns.

+ - **Storage IOPS**: Select storage with sufficient IOPS to handle your read and write operations. Use 'IOPS' metric with 'Max' aggregation on your cluster to see historical storage IOPS usage.

+ - **Network**: Ensure adequate network bandwidth to handle data transfer between your application and the database, especially for distributed setups. Make sure you configured host for your MongoDB application to support [accelerated networking](../../../virtual-network/accelerated-networking-overview.md) technologies such as SR-IOV.

+4. **Scale appropriately**

+ - **Vertical scaling**: Scale compute / RAM up and down and scale storage up.

+ - Compute: Increase the vCore / RAM on a cluster if your workload requires temporary increase or is often crossing over 70% of CPU utilization for prolonged periods.

+ - Make sure you have appropriate data retention in your Azure Cosmos DB for MongoDB vCore database. Retention allows you to avoid unnecessary storage use. Monitor storage usage by setting alerts on the 'Storage percent' and/or 'Storage used' metrics with 'Max' aggregation. Consider increase storage as your workload size crosses 70% usage.

+ - **Horizontal scaling**: Consider using multiple shards for your cluster to distribute your data across multiple Azure Cosmos DB for MongoDB vCore nodes for performance gains and better capacity management as your workload grows. This is especially useful for large datasets (over 2-4 TiB) and high-throughput applications.

+5. **Test and iterate**

+ - **Benchmarking**: Perform measurement for the most frequently used queries with different configurations to determine the impact on performance. Use CPU/RAM and IOPS metrics and application-level benchmarking.

+ - **Load testing**: Conduct load testing to simulate production workloads and validate the performance of your chosen configuration.

+ - **Continuous monitoring**: Continuously monitor your Azure Cosmos DB for MongoDB vCore deployment and adjust resources as needed based on changing workloads and usage patterns.

+By systematically evaluating these factors and continuously monitoring and adjusting your configuration, you can ensure that your MongoDB deployment is well-optimized for your specific workload.

+### Considerations for storage

+Deciding on the appropriate storage size for your workload involves several considerations to ensure optimal performance and scalability. Here are considerations for the storage size in Azure Cosmos DB for MongoDB vCore:

+1. **Estimate data size:**

+ - Calculate the expected size of your Azure Cosmos DB for MongoDB vCore data. Consider:

+ - **Current data size:** If migrating from an existing database.

+ - **Growth rate:** Estimate how much data will be added over time.

+ - **Document size and structure:** Understand your data schema and document sizes, as they affect storage efficiency.

+2. **Factor in indexes:**

+ - Azure Cosmos DB for MongoDB vCore uses **[indexes](./indexing.md)** for efficient querying. Indexes consume extra disk space.

+ - Estimate the size of indexes based on:

+ - **Number of indexes**.

+ - **Size of indexed fields**.

+3. **Performance considerations:**

+ - Disk performance impacts database operations, especially for workloads that can't fit their [working set](#working-set-and-memory-considerations) into RAM. Consider:

+ - **I/O throughput:** IOPS, or Input/Output Operations Per Second, is the number of requests that are sent to storage disks in one second. The larger storage size comes with more IOPS. Ensure adequate throughput for read/write operations. Use 'IOPS' metric with 'Max' aggregation to monitor used IOPS on your cluster.

+ - **Latency:** Latency is the time it takes an application to receive a single request, send it to storage disks, and send the response to the client. Latency is a critical measure of an application's performance in addition to IOPS and throughput. Latency is largely defined by the type of storage used and storage configuration. In a managed service like Azure Cosmos DB for MongoDB, the fast storage such as Premium SSD disks is used with settings optimized to reduce latency.

+4. **Future growth and scalability:**

+ - Plan for future data growth and scalability needs.

+ - Allocate more disk space beyond current needs to accommodate growth without frequent storage expansions.

+5. **Example calculation**:

+ - Suppose your initial data size is 500 GiB.

+ - With indexes, it might grow to 700 GiB.

+ - If you anticipate doubling the data in two years, plan for 1.4 TiB (700 GiB * 2).

+ - Add a buffer for overhead, growth, and operational needs.

+ - You might want to start with 1 TiB storage today and upscale it to 2 TiB once its size grows over 800 GiB.

+Deciding on storage size involves a combination of estimating current and future data needs, considering indexing and compression, and ensuring adequate performance and scalability. Regular monitoring and adjustment based on actual usage and growth trends are also crucial to maintaining optimal MongoDB performance.

+Azure Cosmos DB for NoSQL now offers vector indexing and search in preview. This feature is designed to handle high-dimensional vectors, enabling efficient and accurate vector search at any scale. You can now store vectors directly in the documents alongside your data. Each document in your database can contain not only traditional schema-free data, but also high-dimensional vectors as other properties of the documents. This colocation of data and vectors allows for efficient indexing and searching, as the vectors are stored in the same logical unit as the data they represent. Keeping vectors and data together simplifies data management, AI application architectures, and the efficiency of vector-based operations.

+Vector search for Azure Cosmos DB for NoSQL requires preview feature registration on the Features page of your Azure Cosmos DB. Follow the below steps to register:

+ * [dot product](https://en.wikipedia.org/wiki/Dot_product), which has values from -inf (least similar) to +inf (most similar).

+Once you created a container with the desired vector policy, and inserted vector data into the container, you can conduct a vector search using the [Vector Distance](query/vectordistance.md) system function in a query. An example of a NoSQL query that projects the similarity score as the alias `SimilarityScore`, and sorts in order of most-similar to least-similar:

+The recommendations that appear in your environment are based on the resources that you're protecting and on your customized configuration.

+To learn about actions that you can take in response to these recommendations, see [Remediate recommendations in Defender for Cloud](implement-security-recommendations.md).

+## Azure API recommendations

+### Microsoft Defender for APIs should be enabled

+**Description & related policy**: Enable the Defender for APIs plan to discover and protect API resources against attacks and security misconfigurations. [Learn more](defender-for-apis-deploy.md)

+**Severity**: High

+### Azure API Management APIs should be onboarded to Defender for APIs

+**Description & related policy**: Onboarding APIs to Defender for APIs requires compute and memory utilization on the Azure API Management service. Monitor performance of your Azure API Management service while onboarding APIs, and scale out your Azure API Management resources as needed.

+**Severity**: High

+### API endpoints that are unused should be disabled and removed from the Azure API Management service

+**Description & related policy**: As a security best practice, API endpoints that haven't received traffic for 30 days are considered unused, and should be removed from the Azure API Management service. Keeping unused API endpoints might pose a security risk. These might be APIs that should have been deprecated from the Azure API Management service, but have accidentally been left active. Such APIs typically do not receive the most up-to-date security coverage.

+**Severity**: Low

+### API endpoints in Azure API Management should be authenticated

+**Description & related policy**: API endpoints published within Azure API Management should enforce authentication to help minimize security risk. Authentication mechanisms are sometimes implemented incorrectly or are missing. This allows attackers to exploit implementation flaws and to access data. For APIs published in Azure API Management, this recommendation assesses authentication through verifying the presence of Azure API Management subscription keys for APIs or products where subscription is required, and the execution of policies for validating [JWT](../api-management/validate-jwt-policy.md), [client certificates](../api-management/validate-client-certificate-policy.md), and [Microsoft Entra](../api-management/validate-azure-ad-token-policy.md) tokens. If none of these authentication mechanisms are executed during the API call, the API will receive this recommendation.

+**Severity**: High

+## API management recommendations

+### API Management subscriptions should not be scoped to all APIs

+**Description & related policy**: API Management subscriptions should be scoped to a product or an individual API instead of all APIs, which could result in excessive data exposure.

+**Severity**: Medium

+### API Management calls to API backends should not bypass certificate thumbprint or name validation

+**Description & related policy**: API Management should validate the backend server certificate for all API calls. Enable SSL certificate thumbprint and name validation to improve the API security.

+**Severity**: Medium

+### API Management direct management endpoint should not be enabled

+**Description & related policy**: The direct management REST API in Azure API Management bypasses Azure Resource Manager role-based access control, authorization, and throttling mechanisms, thus increasing the vulnerability of your service.

+**Severity**: Low

+### API Management APIs should use only encrypted protocols

+**Description & related policy**: APIs should be available only through encrypted protocols, like HTTPS or WSS. Avoid using unsecured protocols, such as HTTP or WS to ensure security of data in transit.

+**Severity**: High

+### API Management secret named values should be stored in Azure Key Vault

+**Description & related policy**: Named values are a collection of name and value pairs in each API Management service. Secret values can be stored either as encrypted text in API Management (custom secrets) or by referencing secrets in Azure Key Vault. Reference secret named values from Azure Key Vault to improve security of API Management and secrets. Azure Key Vault supports granular access management and secret rotation policies.

+**Severity**: Medium

+### API Management should disable public network access to the service configuration endpoints

+**Description & related policy**: To improve the security of API Management services, restrict connectivity to service configuration endpoints, like direct access management API, Git configuration management endpoint, or self-hosted gateways configuration endpoint.

+**Severity**: Medium

+### API Management minimum API version should be set to 2019-12-01 or higher

+**Description & related policy**: To prevent service secrets from being shared with read-only users, the minimum API version should be set to 2019-12-01 or higher.

+**Severity**: Medium

+### API Management calls to API backends should be authenticated

+**Description & related policy**: Calls from API Management to backends should use some form of authentication, whether via certificates or credentials. Does not apply to Service Fabric backends.

+ Title: Reference table for all compute security recommendations in Microsoft Defender for Cloud

+description: This article lists all Microsoft Defender for Cloud compute security recommendations that help you harden and protect your resources.

+ai-usage: ai-assisted

+# Compute security recommendations

+This article lists all the multicloud compute security recommendations you might see in Microsoft Defender for Cloud.

+The recommendations that appear in your environment are based on the resources that you're protecting and on your customized configuration.

+To learn about actions that you can take in response to these recommendations, see [Remediate recommendations in Defender for Cloud](implement-security-recommendations.md).

+> [!TIP]

+> If a recommendation description says *No related policy*, usually it's because that recommendation is dependent on a different recommendation.

+>

+> For example, the recommendation *Endpoint protection health failures should be remediated* relies on the recommendation that checks whether an endpoint protection solution is installed (*Endpoint protection solution should be installed*). The underlying recommendation *does* have a policy.

+> Limiting policies to only foundational recommendations simplifies policy management.

+**Description**: This control checks whether the compliance status of the Amazon EC2 Systems Manager patch compliance is COMPLIANT or NON_COMPLIANT after the patch installation on the instance.

+It only checks instances managed by AWS Systems Manager Patch Manager.

+It doesn't check whether the patch was applied within the 30-day limit prescribed by PCI DSS requirement '6.2'.

+It also doesn't validate whether the patches applied were classified as security patches.

+You should create patching groups with the appropriate baseline settings and ensure in-scope systems are managed by those patch groups in Systems Manager. For more information about patch groups, see [AWS Systems Manager User Guide](https://docs.aws.amazon.com/systems-manager/latest/userguide/sysman-patch-group-tagging.html).

+**Description**: This control checks whether Amazon Elastic File System is configured to encrypt the file data using AWS KMS. The check fails in the following cases:

+*"[Encrypted](https://docs.aws.amazon.com/efs/latest/ug/API_DescribeFileSystems.html)" is set to "false" in the DescribeFileSystems response.

+ The "[KmsKeyId](https://docs.aws.amazon.com/efs/latest/ug/API_DescribeFileSystems.html)" key in the [DescribeFileSystems](https://docs.aws.amazon.com/efs/latest/ug/API_DescribeFileSystems.html) response doesn't match the KmsKeyId parameter for [efs-encrypted-check](https://docs.aws.amazon.com/config/latest/developerguide/efs-encrypted-check.html).

+ Note that this control doesn't use the "KmsKeyId" parameter for [efs-encrypted-check](https://docs.aws.amazon.com/config/latest/developerguide/efs-encrypted-check.html). It only checks the value of "Encrypted". For an added layer of security for your sensitive data in Amazon EFS, you should create encrypted file systems.

+ Amazon EFS supports encryption for file systems at-rest. You can enable encryption of data at rest when you create an Amazon EFS file system.

+To learn more about Amazon EFS encryption, see [Data encryption in Amazon EFS](https://docs.aws.amazon.com/efs/latest/ug/encryption.html) in the Amazon Elastic File System User Guide.

+**Description**: This control checks whether an Amazon CloudFront distribution is configured with an origin group that has two or more origins.

+CloudFront origin failover can increase availability. Origin failover automatically redirects traffic to a secondary origin if the primary origin is unavailable or if it returns specific HTTP response status codes.

+**Severity**: Medium

+### [CodeBuild GitHub or Bitbucket source repository URLs should use OAuth](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/9694d4ef-f21a-40b7-b535-618ac5c5d21e)

+**Description**: This control checks whether the GitHub or Bitbucket source repository URL contains either personal access tokens or a user name and password.

+Authentication credentials should never be stored or transmitted in clear text or appear in the repository URL. Instead of personal access tokens or user name and password, you should use OAuth to grant authorization for accessing GitHub or Bitbucket repositories.

+ Using personal access tokens or a user name and password could expose your credentials to unintended data exposure and unauthorized access.

+**Description**: This control checks whether a DAX cluster is encrypted at rest.

+ Encrypting data at rest reduces the risk of data stored on disk being accessed by a user not authenticated to AWS. The encryption adds another set of access controls to limit the ability of unauthorized users to access to the data.

+ For example, API permissions are required to decrypt the data before it can be read.

+**Severity**: Medium

+### [DynamoDB tables should automatically scale capacity with demand](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/47476790-2527-4bdb-b839-3b48ed18dccf)

+**Description**: This control checks whether an Amazon DynamoDB table can scale its read and write capacity as needed. This control passes if the table uses either on-demand capacity mode or provisioned mode with auto scaling configured.

+ Scaling capacity with demand avoids throttling exceptions, which helps to maintain availability of your applications.

+**Severity**: Medium

+**Description**: This control checks whether the status of the AWS Systems Manager association compliance is COMPLIANT or NON_COMPLIANT after the association is run on an instance. The control passes if the association compliance status is COMPLIANT.

+A State Manager association is a configuration that is assigned to your managed instances. The configuration defines the state that you want to maintain on your instances. For example, an association can specify that antivirus software must be installed and running on your instances, or that certain ports must be closed.

+After you create one or more State Manager associations, compliance status information is immediately available to you in the console or in response to AWS CLI commands or corresponding Systems Manager API operations. For associations, "Configuration" Compliance shows statuses of Compliant or Non-compliant and the severity level assigned to the association, such as *Critical* or *Medium*. To learn more about State Manager association compliance, see [About State Manager association compliance](https://docs.aws.amazon.com/systems-manager/latest/userguide/sysman-compliance-https://docsupdatetracker.net/about.html#sysman-compliance-about-association) in the AWS Systems Manager User Guide.

+**Description**: This control checks whether a Lambda function is configured with a dead-letter queue. The control fails if the Lambda function isn't configured with a dead-letter queue.

+As an alternative to an on-failure destination, you can configure your function with a dead-letter queue to save discarded events for further processing.

+ A dead-letter queue acts the same as an on-failure destination. It's used when an event fails all processing attempts or expires without being processed.

+A dead-letter queue allows you to look back at errors or failed requests to your Lambda function to debug or identify unusual behavior.

+From a security perspective, it's important to understand why your function failed and to ensure that your function doesn't drop data or compromise data security as a result.

+ For example, if your function can't communicate to an underlying resource, that could be a symptom of a denial of service (DoS) attack elsewhere in the network.

+[Lambda runtimes](https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html) are built around a combination of operating system, programming language, and software libraries that are subject to maintenance and security updates. When a runtime component is no longer supported for security updates, Lambda deprecates the runtime. Even though you can't create functions that use the deprecated runtime, the function is still available to process invocation events. Make sure that your Lambda functions are current and don't use out-of-date runtime environments.

+### [Ensure 'Block Project-wide SSH keys' is enabled for VM instances](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/00f8a6a6-cf69-4c11-822e-3ebf4910e545)

+**Description**: It's recommended to use Instance specific SSH key(s) instead of using common/shared project-wide SSH key(s) to access Instances.

+Project-wide SSH keys are stored in Compute/Project-meta-data. Project wide SSH keys can be used to log in into all the instances within project. Using project-wide SSH keys eases the SSH key management but if compromised, poses the security risk that can affect all the instances within project.

+ It's recommended to use Instance specific SSH keys that can limit the attack surface if the SSH keys are compromised.

+**Severity**: Medium

+### [Ensure Compute instances are launched with Shielded VM enabled](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/1a4b3b3a-7de9-4aa4-a29b-580d59b43f79)

+**Description**: To defend against advanced threats and ensure that the boot loader and firmware on your VMs are signed and untampered, it's recommended that Compute instances are launched with Shielded VM enabled.

+Shielded VMs are VMs on Google Cloud Platform hardened by a set of security controls that help defend against ```rootkits``` and ```bootkits```.

+Shielded VM offers verifiable integrity of your Compute Engine VM instances, so you can be confident your instances haven't been compromised by boot- or kernel-level malware or rootkits.

+Shielded VM's verifiable integrity is achieved through the use of Secure Boot, virtual trusted platform module (vTPM)-enabled Measured Boot, and integrity monitoring.

+Shielded VM instances run firmware that is signed and verified using Google's Certificate Authority, ensuring that the instance's firmware is unmodified and establishing the root of trust for Secure Boot.

+Integrity monitoring helps you understand and make decisions about the state of your VM instances and the Shielded VM vTPM enables Measured Boot by performing the measurements needed to create a known good boot baseline, called the integrity policy baseline.

+The integrity policy baseline is used for comparison with measurements from subsequent VM boots to determine if anything has changed.

+Secure Boot helps ensure that the system only runs authentic software by verifying the digital signature of all boot components, and halting the boot process if signature verification fails.

+**Severity**: High

+### [Ensure 'Enable connecting to serial ports' is not enabled for VM Instance](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/7e060336-2c9e-4289-a2a6-8d301bad47bb)

+**Description**: Interacting with a serial port is often referred to as the serial console, which is similar to using a terminal window, in that input and output is entirely in text mode and there's no graphical interface or mouse support.

+If you enable the interactive serial console on an instance, clients can attempt to connect to that instance from any IP address. Therefore interactive serial console support should be disabled.

+A virtual machine instance has four virtual serial ports. Interacting with a serial port is similar to using a terminal window, in that input and output is entirely in text mode and there's no graphical interface or mouse support.

+The instance's operating system, BIOS, and other system-level entities often write output to the serial ports, and can accept input such as commands or answers to prompts.

+Typically, these system-level entities use the first serial port (port 1) and serial port 1 is often referred to as the serial console.

+The interactive serial console doesn't support IP-based access restrictions such as IP allowlists. If you enable the interactive serial console on an instance, clients can attempt to connect to that instance from any IP address.

+This allows anybody to connect to that instance if they know the correct SSH key, username, project ID, zone, and instance name.

+Therefore interactive serial console support should be disabled.

+**Severity**: Medium

+### [Ensure 'log_duration' database flag for Cloud SQL PostgreSQL instance is set to 'on'](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/272820a7-06ce-44b3-8318-4ec1f82237dc)

+**Description**: Enabling the log_hostname setting causes the duration of each completed statement to be logged.

+ This doesn't logs the text of the query and thus behaves different from the log_min_duration_statement flag.

+ This parameter can't be changed after session start.

+ Monitoring the time taken to execute the queries can be crucial in identifying any resource hogging queries and assessing the performance of the server.

+ Further steps such as load balancing and use of optimized queries can be taken to ensure the performance and stability of the server.

+ This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure 'log_executor_stats' database flag for Cloud SQL PostgreSQL instance is set to 'off'](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/19711549-76eb-4f1f-b43b-b1048e66c1f0)

+**Description**: The PostgreSQL executor is responsible to execute the plan handed over by the PostgreSQL planner.

+ The executor processes the plan recursively to extract the required set of rows.

+ The "log_executor_stats" flag controls the inclusion of PostgreSQL executor performance statistics in the PostgreSQL logs for each query.

+ The "log_executor_stats" flag enables a crude profiling method for logging PostgreSQL executor performance statistics, which even though can be useful for troubleshooting, it might increase the number of logs significantly and have performance overhead.

+ This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure 'log_min_error_statement' database flag for Cloud SQL PostgreSQL instance is set to 'Error' or stricter](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/50a1058e-925b-4998-9d93-5eaa8f7021a3)

+**Description**: The "log_min_error_statement" flag defines the minimum message severity level that is considered as an error statement.

+ Messages for error statements are logged with the SQL statement.

+ Valid values include "DEBUG5," "DEBUG4," "DEBUG3," "DEBUG2," "DEBUG1," "INFO," "NOTICE," "WARNING," "ERROR," "LOG," "FATAL," and "PANIC."

+ Each severity level includes the subsequent levels mentioned above.

+ Ensure a value of ERROR or stricter is set.

+ Auditing helps in troubleshooting operational problems and also permits forensic analysis.

+ If "log_min_error_statement" isn't set to the correct value, messages might not be classified as error messages appropriately.

+ Considering general log messages as error messages would make is difficult to find actual errors and considering only stricter severity levels as error messages might skip actual errors to log their SQL statements.

+ The "log_min_error_statement" flag should be set to "ERROR" or stricter.

+ This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure 'log_parser_stats' database flag for Cloud SQL PostgreSQL instance is set to 'off'](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/a6efc275-b1c1-4003-8e85-2f30b2eb56e6)

+**Description**: The PostgreSQL planner/optimizer is responsible to parse and verify the syntax of each query received by the server.

+ If the syntax is correct a "parse tree" is built up else an error is generated.

+ The "log_parser_stats" flag controls the inclusion of parser performance statistics in the PostgreSQL logs for each query.

+ The "log_parser_stats" flag enables a crude profiling method for logging parser performance statistics, which even though can be useful for troubleshooting, it might increase the number of logs significantly and have performance overhead.

+ This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure 'log_planner_stats' database flag for Cloud SQL PostgreSQL instance is set to 'off'](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/7d87879a-d498-4e61-b552-b34463f87f83)

+**Description**: The same SQL query can be executed in multiple ways and still produce different results.

+ The PostgreSQL planner/optimizer is responsible to create an optimal execution plan for each query.

+ The "log_planner_stats" flag controls the inclusion of PostgreSQL planner performance statistics in the PostgreSQL logs for each query.

+ The "log_planner_stats" flag enables a crude profiling method for logging PostgreSQL planner performance statistics, which even though can be useful for troubleshooting, it might increase the number of logs significantly and have performance overhead.

+ This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure 'log_statement_stats' database flag for Cloud SQL PostgreSQL instance is set to 'off'](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/c36e73b7-ee30-4684-a1ad-2b878d2b10bf)

+**Description**: The "log_statement_stats" flag controls the inclusion of end to end performance statistics of a SQL query in the PostgreSQL logs for each query.

+ This can't be enabled with other module statistics (*log_parser_stats*, *log_planner_stats*, *log_executor_stats*).

+ The "log_statement_stats" flag enables a crude profiling method for logging end to end performance statistics of a SQL query.

+ This can be useful for troubleshooting but might increase the number of logs significantly and have performance overhead.

+ This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure that Compute instances do not have public IP addresses](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/8bdd13ad-a9d2-4910-8b06-9c4cddb55abb)

+**Description**: Compute instances shouldn't be configured to have external IP addresses.

+To reduce your attack surface, Compute instances shouldn't have public IP addresses. Instead, instances should be configured behind load balancers, to minimize the instance's exposure to the internet.

+Instances created by GKE should be excluded because some of them have external IP addresses and can't be changed by editing the instance settings.

+These VMs have names that start with ```gke-``` and are labeled ```goog-gke-node```.

+**Severity**: High

+### [Ensure that instances are not configured to use the default service account](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/a107c44c-75e4-4607-b1b0-cd5cfcf249e0)

+**Description**: It's recommended to configure your instance to not use the default Compute Engine service account because it has the Editor role on the project.

+The default Compute Engine service account has the Editor role on the project, which allows read and write access to most Google Cloud Services.

+To defend against privilege escalations if your VM is compromised, and to prevent an attacker from gaining access to all of your projects, it's recommended to not use the default Compute Engine service account.

+Instead, you should create a new service account and assigning only the permissions needed by your instance.

+The default Compute Engine service account is named `[PROJECT_NUMBER]- compute@developer.gserviceaccount.com`.

+VMs created by GKE should be excluded. These VMs have names that start with ```gke-``` and are labeled ```goog-gke-node```.

+**Severity**: High

+### [Ensure that instances are not configured to use the default service account with full access to all Cloud APIs](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/a8c1fcf1-ca66-4fc1-b5e6-51d7f4f76782)

+**Description**: To support principle of least privileges and prevent potential privilege escalation, it's recommended that instances aren't assigned to default service account "Compute Engine default service account" with Scope "Allow full access to all Cloud APIs."

+Along with ability to optionally create, manage, and use user managed custom service accounts, Google Compute Engine provides default service account "Compute Engine default service account" for an instance to access necessary cloud services.

+"Project Editor" role is assigned to "Compute Engine default service account" hence, This service account has almost all capabilities over all cloud services except billing.

+However, when "Compute Engine default service account" assigned to an instance it can operate in three scopes.

+- Allow default access: Allows only minimum access required to run an Instance (Least Privileges).

+- Allow full access to all Cloud APIs: Allow full access to all the cloud APIs/Services (Too much access).

+- Set access for each API: Allows Instance administrator to choose only those APIs that are needed to perform specific business functionality expected by instance.

+When an instance is configured with "Compute Engine default service account" with Scope "Allow full access to all Cloud APIs," based on IAM roles assigned to the user(s) accessing Instance,

+it might allow user to perform cloud operations/API calls that user isn't supposed to perform leading to successful privilege escalation.

+VMs created by GKE should be excluded. These VMs have names that start with ```gke-``` and are labeled ```goog-gke-node```.

+**Severity**: Medium

+### [Ensure that IP forwarding is not enabled on Instances](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/0ba588a6-4539-4e67-bc62-d7b2b51300fb)

+**Description**: Compute Engine instance can't forward a packet unless the source IP address of the packet matches the IP address of the instance. Similarly, GCP won't deliver a packet whose destination IP address is different than the IP address of the instance receiving the packet.

+ However, both capabilities are required if you want to use instances to help route packets.

+Forwarding of data packets should be disabled to prevent data loss or information disclosure.

+Compute Engine instance can't forward a packet unless the source IP address of the packet matches the IP address of the instance. Similarly, GCP won't deliver a packet whose destination IP address is different than the IP address of the instance receiving the packet.

+ However, both capabilities are required if you want to use instances to help route packets. To enable this source and destination IP check, disable the canIpForward field, which allows an instance to send and receive packets with nonmatching destination or source IPs.

+**Severity**: Medium

+### [Ensure that the 'log_checkpoints' database flag for Cloud SQL PostgreSQL instance is set to 'on'](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/a2404629-0132-4ab3-839e-8389dbe9fe98)

+**Description**: Ensure that the log_checkpoints database flag for the Cloud SQL PostgreSQL instance is set to on.

+Enabling log_checkpoints causes checkpoints and restart points to be logged in the server log. Some statistics are included in the log messages, including the number of buffers written and the time spent writing them.

+ This parameter can only be set in the postgresql.conf file or on the server command line. This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure that the 'log_lock_waits' database flag for Cloud SQL PostgreSQL instance is set to 'on'](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/8191f530-fde7-4177-827a-43ce0f69ffe7)

+**Description**: Enabling the "log_lock_waits" flag for a PostgreSQL instance creates a log for any session waits that take longer than the allotted "deadlock_timeout" time to acquire a lock.

+ The deadlock timeout defines the time to wait on a lock before checking for any conditions. Frequent run overs on deadlock timeout can be an indication of an underlying issue.

+ Logging such waits on locks by enabling the log_lock_waits flag can be used to identify poor performance due to locking delays or if a specially crafted SQL is attempting to starve resources through holding locks for excessive amounts of time.

+ This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure that the 'log_min_duration_statement' database flag for Cloud SQL PostgreSQL instance is set to '-1'](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/1c9e237b-419f-4e73-b43a-94b5863dd73e)

+**Description**: The "log_min_duration_statement" flag defines the minimum amount of execution time of a statement in milliseconds where the total duration of the statement is logged. Ensure that "log_min_duration_statement" is disabled, that is, a value of -1 is set.

+ Logging SQL statements might include sensitive information that shouldn't be recorded in logs. This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure that the 'log_min_messages' database flag for Cloud SQL PostgreSQL instance is set appropriately](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/492fed4e-1871-4c12-948d-074ee0f07559)

+**Description**: The "log_min_error_statement" flag defines the minimum message severity level that is considered as an error statement.

+ Messages for error statements are logged with the SQL statement.

+ Valid values include "DEBUG5," "DEBUG4," "DEBUG3," "DEBUG2," "DEBUG1," "INFO," "NOTICE," "WARNING," "ERROR," "LOG," "FATAL," and "PANIC."

+ Each severity level includes the subsequent levels mentioned above.

+ To effectively turn off logging failing statements, set this parameter to PANIC.

+ ERROR is considered the best practice setting. Changes should only be made in accordance with the organization's logging policy.

+Auditing helps in troubleshooting operational problems and also permits forensic analysis.

+ If "log_min_error_statement" isn't set to the correct value, messages might not be classified as error messages appropriately.

+ Considering general log messages as error messages would make it difficult to find actual errors, while considering only stricter severity levels as error messages might skip actual errors to log their SQL statements.

+ The "log_min_error_statement" flag should be set in accordance with the organization's logging policy.

+ This recommendation is applicable to PostgreSQL database instances.

+**Severity**: Low

+### [Ensure that the 'log_temp_files' database flag for Cloud SQL PostgreSQL instance is set to '0'](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/29622fc0-14dc-4d65-a5a8-e9a39ffc4b62)

+**Description**: PostgreSQL can create a temporary file for actions such as sorting, hashing, and temporary query results when these operations exceed "work_mem."

+ The "log_temp_files" flag controls logging names and the file size when it's deleted.

+ Configuring "log_temp_files" to 0 causes all temporary file information to be logged, while positive values log only files whose size is greater than or equal to the specified number of kilobytes.

+ A value of "-1" disables temporary file information logging.

+ If all temporary files aren't logged, it might be more difficult to identify potential performance issues that might be due to either poor application coding or deliberate resource starvation attempts.

+**Severity**: Low

+### [Ensure VM disks for critical VMs are encrypted with Customer-Supplied Encryption Key](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/6ca40f30-2508-4c90-85b6-36564b909364)

+**Description**: Customer-Supplied Encryption Keys (CSEK) are a feature in Google Cloud Storage and Google Compute Engine.

+ If you supply your own encryption keys, Google uses your key to protect the Google-generated keys used to encrypt and decrypt your data.

+ By default, Google Compute Engine encrypts all data at rest.

+ Compute Engine handles and manages this encryption for you without any additional actions on your part.

+ However, if you wanted to control and manage this encryption yourself, you can provide your own encryption keys.

+By default, Google Compute Engine encrypts all data at rest. Compute Engine handles and manages this encryption for you without any additional actions on your part.

+However, if you wanted to control and manage this encryption yourself, you can provide your own encryption keys.

+If you provide your own encryption keys, Compute Engine uses your key to protect the Google-generated keys used to encrypt and decrypt your data.

+Only users who can provide the correct key can use resources protected by a customer-supplied encryption key.

+Google doesn't store your keys on its servers and can't access your protected data unless you provide the key.

+This also means that if you forget or lose your key, there's no way for Google to recover the key or to recover any data encrypted with the lost key.

+At least business critical VMs should have VM disks encrypted with CSEK.

+# Container security recommendations

+This article lists all the container security recommendations you might see in Microsoft Defender for Cloud.

+The recommendations that appear in your environment are based on the resources that you're protecting and on your customized configuration.

+> [!TIP]

+> If a recommendation description says *No related policy*, usually it's because that recommendation is dependent on a different recommendation.

+>

+> For example, the recommendation *Endpoint protection health failures should be remediated* relies on the recommendation that checks whether an endpoint protection solution is installed (*Endpoint protection solution should be installed*). The underlying recommendation *does* have a policy.

+> Limiting policies to only foundational recommendations simplifies policy management.

+# Data security recommendations

+This article lists all the data security recommendations you might see in Microsoft Defender for Cloud.

+The recommendations that appear in your environment are based on the resources that you're protecting and on your customized configuration.

+To learn about actions that you can take in response to these recommendations, see [Remediate recommendations in Defender for Cloud](implement-security-recommendations.md).

+> [!TIP]

+> If a recommendation description says *No related policy*, usually it's because that recommendation is dependent on a different recommendation.

+>

+> For example, the recommendation *Endpoint protection health failures should be remediated* relies on the recommendation that checks whether an endpoint protection solution is installed (*Endpoint protection solution should be installed*). The underlying recommendation *does* have a policy.

+> Limiting policies to only foundational recommendations simplifies policy management.

+**Description**: This control checks whether storage encryption is enabled for your Amazon RDS DB instances.

+This control is intended for RDS DB instances. However, it can also generate findings for Aurora DB instances, Neptune DB instances, and Amazon DocumentDB clusters. If these findings aren't useful, then you can suppress them.

+ For an added layer of security for your sensitive data in RDS DB instances, you should configure your RDS DB instances to be encrypted at rest. To encrypt your RDS DB instances and snapshots at rest, enable the encryption option for your RDS DB instances. Data that is encrypted at rest includes the underlying storage for DB instances, its automated backups, read replicas, and snapshots.

+RDS encrypted DB instances use the open standard AES-256 encryption algorithm to encrypt your data on the server that hosts your RDS DB instances. After your data is encrypted, Amazon RDS handles authentication of access and decryption of your data transparently with a minimal impact on performance. You don't need to modify your database client applications to use encryption.

+Amazon RDS encryption is currently available for all database engines and storage types. Amazon RDS encryption is available for most DB instance classes.

+**Description**: This control checks whether your secrets have been accessed within a specified number of days. The default value is 90 days. If a secret wasn't accessed within the defined number of days, this control fails.

+Deleting unused secrets is as important as rotating secrets. Unused secrets can be abused by their former users, who no longer need access to these secrets. Also, as more users get access to a secret, someone might have mishandled and leaked it to an unauthorized entity, which increases the risk of abuse. Deleting unused secrets helps revoke secret access from users who no longer need it. It also helps to reduce the cost of using Secrets Manager. Therefore, it's essential to routinely delete unused secrets.

+**Description**: This control checks whether an AWS Secrets Manager secret rotated successfully based on the rotation schedule. The control fails if **RotationOccurringAsScheduled** is **false**. The control doesn't evaluate secrets that don't have rotation configured.

+Secrets Manager helps you improve the security posture of your organization. Secrets include database credentials, passwords, and third-party API keys. You can use Secrets Manager to store secrets centrally, encrypt secrets automatically, control access to secrets, and rotate secrets safely and automatically.

+Secrets Manager can rotate secrets. You can use rotation to replace long-term secrets with short-term ones. Rotating your secrets limits how long an unauthorized user can use a compromised secret. For this reason, you should rotate your secrets frequently.

+In addition to configuring secrets to rotate automatically, you should ensure that those secrets rotate successfully based on the rotation schedule.

+To learn more about rotation, see [Rotating your AWS Secrets Manager secrets](https://docs.aws.amazon.com/secretsmanager/latest/userguide/rotating-secrets.html) in the AWS Secrets Manager User Guide.

+**Description**: This control checks whether your secrets have been rotated at least once within 90 days.

+Rotating secrets can help you to reduce the risk of an unauthorized use of your secrets in your AWS account. Examples include database credentials, passwords, third-party API keys, and even arbitrary text. If you don't change your secrets for a long period of time, the secrets are more likely to be compromised.

+As more users get access to a secret, it can become more likely that someone mishandled and leaked it to an unauthorized entity. Secrets can be leaked through logs and cache data. They can be shared for debugging purposes and not changed or revoked once the debugging completes. For all these reasons, secrets should be rotated frequently.

+You can configure your secrets for automatic rotation in AWS Secrets Manager. With automatic rotation, you can replace long-term secrets with short-term ones, significantly reducing the risk of compromise.

+Security Hub recommends that you enable rotation for your Secrets Manager secrets. To learn more about rotation, see [Rotating your AWS Secrets Manager secrets](https://docs.aws.amazon.com/secretsmanager/latest/userguide/rotating-secrets.html) in the AWS Secrets Manager User Guide.

+**Description**: It's recommended that uniform bucket-level access is enabled on Cloud Storage buckets.

+ It's recommended to use uniform bucket-level access to unify and simplify how you grant access to your Cloud Storage resources.

+ Cloud Storage offers two systems for granting users permission to access your buckets and objects:

+ Cloud Identity and Access Management (Cloud IAM) and Access Control Lists (ACLs).

+ These systems act in parallel - in order for a user to access a Cloud Storage resource, only one of the systems needs to grant the user permission.

+ Cloud IAM is used throughout Google Cloud and allows you to grant a variety of permissions at the bucket and project levels.

+ ACLs are used only by Cloud Storage and have limited permission options, but they allow you to grant permissions on a per-object basis.

+ In order to support a uniform permissioning system, Cloud Storage has uniform bucket-level access.

+ Using this feature disables ACLs for all Cloud Storage resources:

+ access to Cloud Storage resources then is granted exclusively through Cloud IAM.

+ Enabling uniform bucket-level access guarantees that if a Storage bucket isn't publicly accessible,

+no object in the bucket is publicly accessible either.

+**Description**: Google Cloud encrypts data at-rest and in-transit, but customer data must be decrypted for processing. Confidential Computing is a breakthrough technology that encrypts data in-use-while it's being processed.

+ Confidential Computing environments keep data encrypted in memory and elsewhere outside the central processing unit (CPU).

+Confidential VMs leverage the Secure Encrypted Virtualization (SEV) feature of AMD EPYC CPUs.

+ Customer data will stay encrypted while it's used, indexed, queried, or trained on.

+ Encryption keys are generated in hardware, per VM, and not exportable. Thanks to built-in hardware optimizations of both performance and security, there's no significant performance penalty to Confidential Computing workloads.

+Confidential Computing enables customers' sensitive code and other data encrypted in memory during processing. Google doesn't have access to the encryption keys.

+Confidential VM can help alleviate concerns about risk related to either dependency on Google infrastructure or Google insiders' access to customer data in the clear.

+**Description**: Enabling retention policies on log buckets will protect logs stored in cloud storage buckets from being overwritten or accidentally deleted.

+ It's recommended to set up retention policies and configure Bucket Lock on all storage buckets that are used as log sinks.

+ Logs can be exported by creating one or more sinks that include a log filter and a destination. As Stackdriver Logging receives new log entries, they're compared against each sink.

+ If a log entry matches a sink's filter, then a copy of the log entry is written to the destination.

+ Sinks can be configured to export logs in storage buckets.

+ It's recommended to configure a data retention policy for these cloud storage buckets and to lock the data retention policy; thus permanently preventing the policy from being reduced or removed.

+ This way, if the system is ever compromised by an attacker or a malicious insider who wants to cover their tracks, the activity logs are definitely preserved for forensics and security investigations.

+**Description**: It's recommended to set "user connections" database flag for Cloud SQL SQL Server instance according to organization-defined value.

+ The "user connections" option specifies the maximum number of simultaneous user connections that are allowed on an instance of SQL Server.

+ The actual number of user connections allowed also depends on the version of SQL Server that you're using, and also the limits of your application or applications and hardware.

+ SQL Server allows a maximum of 32,767 user connections.

+ Because user connections are a dynamic (self-configuring) option, SQL Server adjusts the maximum number of user connections automatically as needed, up to the maximum value allowable.

+ For example, if only 10 users are logged in, 10 user connection objects are allocated.

+ In most cases, you don't have to change the value for this option.

+ The default is 0, which means that the maximum (32,767) user connections are allowed.

+ This recommendation is applicable to SQL Server database instances.

+**Severity**: Low

+### [Ensure 'user options' database flag for Cloud SQL SQL Server instance is not configured](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/fab1e680-86f0-4616-bee9-1b7394e49ade)

+**Description**: It's recommended that, "user options" database flag for Cloud SQL SQL Server instance shouldn't be configured.

+ The "user options" option specifies global defaults for all users.

+ A list of default query processing options is established for the duration of a user's work session.

+ The user options setting allows you to change the default values of the SET options (if the server's default settings aren't appropriate).

+ A user can override these defaults by using the SET statement.

+ You can configure user options dynamically for new logins.

+ After you change the setting of user options, new login sessions use the new setting; current login sessions aren't affected.

+ This recommendation is applicable to SQL Server database instances.

+**Severity**: Low

+### [Logging for GKE clusters should be enabled](https://portal.azure.com/#blade/Microsoft_Azure_Security/RecommendationsBlade/assessmentKey/fa160a2c-e976-41cb-acff-1e1e3f1ed032)

+## Azure DevOps recommendations

+**Description**: DevOps security in Defender for Cloud uses a central console to empower security teams with the ability to protect applications and resources from code to cloud across Azure DevOps. With enablement of GitHub Advanced Security for Azure DevOps (GHAzDO) repositories including GitHub Advanced Security for Azure DevOps, you get findings about secrets, dependencies, and code vulnerabilities in your Azure DevOps repositories surfaced in Microsoft Defender for Cloud.

+**Description**: Secrets were found in code repositories. Remediate immediately to prevent a security breach. Secrets found in repositories can leak, or be discovered by adversaries, leading to compromise of an application or service. The Microsoft Security DevOps credential scanning tool only scans builds on which it is configured to run. Therefore, results might not reflect the complete status of secrets in your repositories.

+**Description**: Dependency vulnerabilities found in code repositories. To improve the security posture of the repositories, it is highly recommended to remediate these vulnerabilities.

+**Description**: Infrastructure as code security configuration issues found in repositories. The issues were detected in template files. To improve the security posture of the related cloud resources, it is highly recommended to remediate these issues.

+### [Azure DevOps pipelines shouldn't have secrets available to builds of forks](https://ms.portal.azure.com/#view/Microsoft_Azure_Security/GenericRecommendationDetailsBlade/assessmentKey/d5711372-9b5f-4926-a711-13dcf51565a6)

+**Description**: Service connections are used to create connections from Azure Pipelines to external and remote services for executing tasks in a job. Pipeline permissions control which pipelines are authorized to use the service connection. To support security of the pipeline operations, service connections shouldn't be granted access to all YAML pipelines. This helps to maintain the principle of least privilege because a vulnerability in components used by one pipeline can be used by an attacker to attack other pipelines with access to critical resources.

+**Description**: API security vulnerabilities found in code repositories. To improve the security posture of the repositories, it is highly recommended to remediate these vulnerabilities.

+**Description**: To prevent unintended or malicious changes from being directly committed, it's important to implement protection policies for the default branch in Azure DevOps repositories. We recommend requiring at least two code reviewers to approve pull requests before the code is merged with the default branch. By requiring approval from a minimum number of two reviewers, you can reduce the risk of unauthorized modifications, which could lead to system instability or security vulnerabilities.<br/><br/> This recommendation is provided in Defender for Cloud foundational security posture, if you have connected Azure DevOps to Defender for Cloud.

+**Description**: To prevent unintended or malicious changes from being directly committed, it's important to implement protection policies for the default branch in Azure DevOps repositories. We recommend prohibiting pull request creators from approving their own submissions to ensure that every change undergoes objective review by someone other than the author. By doing this, you can reduce the risk of unauthorized modifications, which could lead to system instability or security vulnerabilities.<br/><br/> This recommendation is provided in Defender for Cloud foundational security posture, if you have connected Azure DevOps to Defender for Cloud.

+## GitHub recommendations

+### [GitHub organizations should not make action secrets accessible to all repositories](https://portal.azure.com/#view/Microsoft_Azure_Security/GenericRecommendationDetailsBlade/assessmentKey/6331fad3-a7a2-497d-b616-52672057e0f3)

+**Description**: For secrets used in GitHub Action workflows that are stored at the GitHub organization-level, you can use access policies to control which repositories can use organizational secrets. Organization-level secrets let you share secrets between multiple repositories. This reduces the need to create duplicate secrets. However, once a secret is made accessible to a repository, anyone with write access on repository can access the secret from any branch in a workflow. To reduce the attack surface, ensure that the secret is accessible from selected repositories only.<br/><br/> This recommendation is provided in Defender for Cloud foundational security posture, if you have connected Azure DevOps to Defender for Cloud.

+**Severity**: High

+**Description**: Secrets found in code repositories. This should be remediated immediately to prevent a security breach. Secrets found in repositories can be leaked or discovered by adversaries, leading to compromise of an application or service.
