High availability for Aurora

If you have an Aurora Replica:

  • When failing over, Aurora flips the canonical name record (CNAME) for your DB Instance to point at the healthy replica, which in turn is promoted to become the new primary.

If you are running Aurora Serverless:

  • Aurora will automatically recreate the DB instance in a different AZ.

If you do not have an Aurora Replica and are not running Aurora Serverless:

  • Aurora will attempt to create a new DB Instance in the same Availability Zone as the original instance (done on a best-effort basis and may not succeed).
