I am doing a proof-of-concept with Azure SQL with below configuration, let me know if using both fail-over-group and geo-replication together has any potential downsides?
I have SQL Server A,B,C,D in different regions.
A and B are part of same fail-over-group.
A also geo replicates to DB in Servers C and D.
When I failover from SQL server A to B, I also see that C and D now recognizes B as the new primary which is the behavior that I am looking for. But I couldn't find any documentation to support this. Would nice to get confirmation on this behavior.
Thanks!
