Sasha was in the studio a while ago to talk about Azure SQL DB geo-replication, a feature that is quite popular. This session builds on his first session by discussing and showing additional disaster recovery capabilities in Azure SQL DB.

Sasha begins by discussing some of the limitations of geo-replication, including deciding when to manually fail over and manually changing the connection information to the failover database. To address those limitations, Sasha introduces a feature in Azure SQL DB called auto-failover groups, which he discusses at the [03:45] mark. He discusses how this features is implemented, the details how it works, and best practices around uses auto-failover groups.
