Auto-Failover Group

An Azure SQL Database and Managed Instance feature that replicates databases to another region and fails them over together behind stable listener endpoints.

Definition

Failover groups use read-write and read-only listener endpoints that keep the same connection strings after failover, and they support automatic failover policies. They build on geo-replication but act on groups of databases.

Example

Connecting to myfog.database.windows.net keeps working after a regional failover.

Exam tip

If the application must not change connection strings after a regional failover, choose failover groups over plain active geo-replication.
