An Azure region consists of multiple data centers to provide redundancy and availability of your applications. You create Azure resources in defined geographic regions such as East US, North Central US, or West US. This approach gives you flexibility as you design applications to create VMs closest to your users and to meet any legal, compliance, or tax purposes.
It is possible to have multiple resources communicating with each other in different regions. However, it is highly recommended that all resources for AVS be deployed in the same region.
Region pairs in Azure
Within the same geography, each Azure region is associated with another. This strategy provides for resource replication across geography, such as VM storage, which should lessen the likelihood of natural disasters, civil unrest, power failures, or physical network outages hitting both regions simultaneously. Region pairs also have the following advantages:
