Hello Azure enthusiasts !

I have question regarding region outages for resource group and a resource .

Let's say we have RG1 placed in WestUS , and a VNet inside this RG1 but placed in EastUS.

My question here when WestUS region outage occurs , I will be fine managing my VNet resource since it's in EastUS region ? But why in MS documentation here link says it's recommended to place a resource group and a resource in same region ? thus back to my example if we placed both RG1 and the VNet in same region and this region outages , I will be loosing my service .

    Hello Ali El Husseiny,

    Thanks for posting your question in the Microsoft Q&A forum.

    When you have a resource group (RG1) located in the WestUS region and a VNet in the EastUS region, you’re asking if you can still manage your VNet during an outage in the WestUS. The straightforward answer is yes; if the VNet is in EastUS, you should still be able to access and manage it even if WestUS experiences an outage.

    However, the recommendation to keep resources in the same region primarily aims to simplify management and enhance performance. When resources are in different regions, some operations might be subject to latency and potential limitations in inter-region data transfer. Regarding the example you mention—if both the resource group and the VNet are in the same region and that region goes down, you indeed would lose access to those services. That's the trade-off for improved speed and manageability versus geographical redundancy.

    Here's a bit more information related to your situation:

    1. Advantages of Keeping Resources in the Same Region: It reduces latency and potential bottlenecks during data transfer and enables better integration between resources.
    2. Redundancy: Utilizing different regions can provide redundancy in case one region goes down; however, as you identified, you may need to manage services separately across regions.
    3. Resource Mover: For moving resources between regions, Azure has the Resource Mover, which simplifies the process and helps maintain dependencies during moves. You can learn more about it here.

    Hope this helps clarify things! If you have more specific needs or queries, feel free to ask!

    When a resource group (RG1) is placed in one region (e.g., WestUS) and a resource, such as a Virtual Network (VNet), is placed in another region (e.g., EastUS), you may be able to manage the VNet during an outage in the WestUS region. However, the recommendation to keep resources and their resource groups in the same region is primarily for compliance, performance, and management reasons.

    The key points to consider are:

    1. Metadata Storage: The resource group stores metadata about the resources, and this metadata is located in the region where the resource group is created. If the resource group is in WestUS and experiences an outage, any operations that require access to this metadata will be impacted, even if the actual resource (the VNet) is in EastUS.
    2. Control Plane Operations: Control plane operations, which include management tasks like creating, updating, or deleting resources, are routed through the resource group's location. Therefore, if WestUS is down, you may face difficulties managing the VNet, despite it being in EastUS.
    3. Regional Outages: If both regions experience an outage, or if the resource group’s region is unavailable, you will lose the ability to manage the VNet, which is why it is recommended to keep resources and their resource groups in the same region to minimize the impact of regional outages.

    In summary, while you might be able to access the VNet during an outage in WestUS, the management capabilities would be limited due to the dependency on the resource group's metadata and control plane operations. Thus, placing both the resource group and the resources in the same region is a best practice to ensure high availability and manageability.
