Announcing General Availability for Azure Resource Graph (ARG) GET/LIST API
ARG GET/LIST API delivers 10X higher throttling quotas to callers compared to ARG query unlocking a more scalable, resilient way to perform resource lookups in Azure. ARG GET/LIST API is a new platform capability within Azure Resource Graph that provides a high-performance experience for both Point GET and collection GET requests. A key advantage of this capability is its ability to significantly reduce READ throttling for high volume calls efficiently. This is made possible through intelligent control plane routing based on a query parameter controlled by the caller. When a specific query parameter is included, requests are automatically directed to this optimized ARG GET/LIST backend. When the parameter is omitted, requests flow to the Resource provider —ensuring flexibility and backward compatibility. What Challenge Are We Addressing? Azure Read Throttling is a significant challenge for many customers. When services hit throttling limits, applications may experience performance degradation, elevated latency, or even failed requests—issues that can disrupt critical workloads and customer operations. The ARG GET/LIST API is designed to directly address this problem. By routing GET and LIST calls through Azure Resource Graph’s scalable indexing infrastructure and intelligent control-plane routing, it dramatically reduces the likelihood of read throttling. Best of all, it follows the ARM control plane GET APIs request response contract, allowing you to benefit from improved performance and reliability with minimal effort, appending the flag “useResourceGraph=true”. When to use Azure Resource Graph (ARG) GET/LIST API The ARG GET/LIST API is designed for scenarios where you need to retrieve a single resource by its ID or list resources of the same type within a defined scope—whether that's a subscription, resource group, or parent resource. You should consider using the ARG GET/LIST API if your service fits into one or more of the following categories: High Volume of GET Calls Within a Single Scope: Your service issues a large number of GET requests targeting resources within a single subscription or resource group, without the need for cross-subscription queries, complex filters, or joins. Risk of Throttling or Quota Competition: Your service produces a high volume of requests and may encounter issues such as:: Experience throttling during sudden traffic spikes. Quota competition, where other workloads in the same subscription consume shared quota limits, causing your service to be throttled. Bursty traffic patterns, where large volume of GET requests are issued within a short time window, increasing the chance of throttling. Need for High Availability and Faster Performance: Your service depends on consistent; low-latency GET operations for either single-resource lookups or listing resources within a specific scope Note: The ARG GET/LIST API is currently supported only for resources in the resources and computeresources tables. Using the ARG GET/LIST API To get started with the ARG GET/LIST API, begin by assessing whether your scenario aligns with the recommended calling patterns and throttling considerations described earlier. Once confirmed, simply append the parameter &useResourceGraph=true to your eligible GET/LIST API calls. This flag routes your request through the Azure Resource Graph GET/LIST API backend, allowing you to take advantage of its optimized performance and query efficiency. No calls will route to ARG GET/LIST backend automatically. The switch is entirely in the user’s control—the call will route to ARG GET/LIST API only when you explicitly include the useResourceGraph=true parameter in your request. Follow the ARG GET/LIST API contract here - Azure Resource Graph GET/LIST API Guidance - Azure Resource Graph | Microsoft Learn Let’s walk through a simple example of retrieving a Virtual Machine (VM) along with its InstanceView through ARG Query vs. ARM API vs. ARG GET/LIST API to show the difference in the calling experience. Using an ARG Query (via ARG Explorer) In ARG Explorer, you can use Kusto Query Language (KQL) to query resources. A sample query to retrieve a specific VM looks like this: Resources | where type =~ 'microsoft.compute/virtualmachines' | where id =~ '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/microsoft.compute/virtualmachines/{vm}' This query filters the Resource Graph index to return the VM resource. Using the ARM (Compute RP) API The equivalent ARM API call to retrieve the VM with InstanceView is: GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/microsoft.compute/virtualmachines/{vm}?api-version=2024-07-01&$expand=instanceView This hits the Compute Resource Provider, pulls the VM state, and expands the instanceView section. Using the ARG GET/LIST API ARG GET/LIST APIs that follow the same request structure as ARM—but with an additional flag that routes the call through ARG: GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/microsoft.compute/virtualmachines/{vm}?api-version=2024-07-01&$expand=instanceView&useResourceGraph=true The important distinction here is the useResourceGraph=true parameter, which routes the call through ARM to serve the response through ARG’s GET/LIST backend.

At the start of 2025, during the January 2025 ALZ Community Call, we asked everyone for their feedback, via these discussions on our GitHub repo: 1898 & 1978 , on the future of Microsoft Sentinel in the Azure landing zone (ALZ) architecture as we were receiving feedback that it needed some changes and additional clarity from what ALZ was deploying and advising then. We have now worked with customers, partners, and internal teams to figure out what we should update in ALZ around Microsoft Sentinel and Security tooling and have updated the ALZ conceptual architecture to show this. What did ALZ advise and deploy before, by default? Prior to these updates ALZ advised the following: The central Log Analytics Workspace (LAW) in the Management Subscription should Be used to capture all logs, including security/SIEM logs The Microsoft Sentinel solution (called Security) should be installed upon this LAW also And in the accelerators and tooling it deployed, by default: The central Log Analytics Workspace (LAW) in the Management Subscription with the Microsoft Sentinel solution installed Microsoft Sentinel had no additional configuration apart from being installed as a solution on the central LAW What are the changes being made to ALZ from today? Based on the feedback from the GitHub discussions and working with customers, partners and internal teams we are making the following changes: A new dedicated Security Management Group beneath the Platform Management Group A new dedicated Security Subscription placed in the new Security Management Group Nothing will be deployed into this subscription by ALZ by default. This allows: Customers & partners to deploy and manage the Microsoft Sentinel deployment how they wish to The 31-day 10GB/day free trial can be started when the customer or partner is ready to utilise it No longer deploy the Microsoft Sentinel solution (called Security) on the central LAW in the Management Subscription This allows for separating of operational/platform logs from security logs, as per considerations documented in Design a Log Analytics workspace architecture The changes have only been made to our ALZ CAF/MS Learn guidance as of now, and the changes to the accelerators and implementation tools will be made over the coming months 👍 These changes can be seen in the latest ALZ conceptual architecture snippet below The full ALZ conceptual architecture can be seen here on MS Learn. You can also download a Visio or PDF copy of all the ALZ diagrams. What if we have already deployed ALZ? If you have already deployed ALZ and haven't tailored the ALZ default Management Group hierarchy to create a Security Management Group then you can now review and decide whether this is something you'd like to create and align with. While not mandatory, this enhancement to the ALZ architecture is recommended for new customers. The previous approach remains valid; however, feedback from customers, partners, and internal teams indicates that using a dedicated Microsoft Sentinel and Log Analytics Workspace within a separate security-focused Subscription and Management Group is a common real-world practice. To reflect these real-world implementations and feedback, we’re evolving the ALZ conceptual architecture accordingly 👍 Closing We hope you benefit from this update to the ALZ conceptual architecture. As always we welcome any feedback via our GitHub Issues
