Is there a published list of Azure services that depend on the Region Pairs concept to provide redundancy, replication and disaster recovery? As per this document https://learn.microsoft.com/en-us/azure/reliability/regions-paired, "These region pairs are then used by a small number of Azure services to support geo-replication and geo-redundancy. The pairs are also used to support some aspects of disaster recovery"
So,
- What are the "small number" of these Azure services that use region pairs to support geo-replication and geo-redundancy
- What are the services that use these region pairs to support some aspects of DR?
For e.g. if I read about Azure storage redundancy in secondary region here https://docs.azure.cn/en-us/storage/common/storage-redundancy#redundancy-in-a-secondary-region, I can see that it states it uses region pairs to provide geo-redundancy. But this is only possible to find out if I know specifically which Azure service I am looking for. What I am after is a generic list from Azure listing all services that depend/rely on region pairs out-of-the-box to provide support for redundancy, replication & DR
We have a situation where we may need to move away from Region pairs due to requirements, and I would like to understand how can I identify all the Azure services that will get impacted in our design that rely on Region pairs to provide automatic redundancy, resilience and DR.
Thanks

I have contacted you through private messaging. I kindly request that you provide the necessary details so we can arrange a call to resolve this matter.
However, in the mean while to answer your question Unfortunately, there is no published comprehensive list from Microsoft that explicitly catalogs all Azure services that depend on region pairs for geo-replication, geo-redundancy, and disaster recovery.
Below are the Azure Services That Rely on Region Pairs
- Azure Storage Services: Geo-Redundant Storage (GRS) - automatically replicates data to a paired region, Read-Access Geo-Redundant Storage (RA-GRS), Geo-Zone-Redundant Storage (GZRS), This includes Blob, File, Queue, and Table storage services.
- Azure Key Vault uses region pairs for certain redundancy scenarios, though Azure Key Vault uses zone redundant storage within regions that have availability zones azure service fabric - Scale set using keyvault in another region - Stack Overflow
- Azure SQL Database and Managed Instance: Uses GRS for backup storage and supports failover to paired regions in case of regional outages.
- Azure Site Recovery: Supports replication of VMs and workloads to paired regions for DR scenarios.
Let me know if you have any questions via comment, we are happy to assist you.
