Question

A financial services company runs its primary transactional workload on an Amazon Aurora MySQL cluster in the us-east-1 Region. Regulatory requirements dictate that the application must be able to recover in a second Region with an RPO of less than 1 second and an RTO of under 5 minutes in the event of a full Region outage. The solution must minimize replication lag and avoid impacting the performance of the primary cluster. Which approach best meets these requirements?

Accepted Answer

Configure an Amazon Aurora Global Database with a secondary Region cluster and use managed planned failover or unplanned failover to promote the secondary.

Answer

Enable automated Aurora snapshots and copy them to the second Region on an hourly schedule, restoring a new cluster when a failure occurs.

Answer

Create a cross-Region Aurora read replica using standard binlog-based replication and manually promote it during a disaster.

Answer

Deploy the Aurora cluster in a Multi-AZ configuration and rely on automatic failover to a standby in another Availability Zone within us-east-1.
