This article provides answers to common questions about Azure Resource Manager and how you use it for manage resources.
Resource groups
Can a resource group be renamed?
No, you can't rename a resource group. You need to create a new resource group with the desired name and move the resources to the new resource group.
Are resource group names case sensitive?
No, Azure resource group names aren't case sensitive. They're treated as case-insensitive, meaning "ResourceGroup1" and "resourcegroup1" are considered the same.
When using various APIs to retrieve the name for a resource or resource group, the returned value may have different casing than what you originally specified for the name.
For more information about resource group names, see Naming rules and restrictions.
What location should I choose for a resource group?
To ensure state consistency for the resource group, all control plane operations are routed through the resource group's location. When selecting a resource group location, we recommend that you select a location close to where your control operations originate. Typically, this location is the one closest to your current location.
Resources
What happens if two operations update the same resource at the same time?
Azure Resource Manager detects the conflict and permits only one operation to complete successfully. The other operation fails and returns a 409 conflict error. If the blocked operation has the correct state, you can retry the operation.
