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:
