Question

A financial services company runs a production workload on an Amazon Aurora MySQL cluster in us-east-1. The disaster recovery plan requires an RPO of less than 1 second and an RTO of under 5 minutes in a second Region. Management also wants the DR Region to serve low-latency read traffic for reporting users located there during normal operations. Which approach BEST meets all of these requirements?

Accepted Answer

Configure an Aurora global database with a secondary cluster in us-west-2, serving reporting reads locally and promoting the secondary during a disaster.

Answer

Enable automated Aurora snapshots and copy them to us-west-2 on a scheduled basis, restoring a new cluster there if the primary Region fails.

Answer

Create a cross-Region Aurora read replica in us-west-2 using binlog replication and manually promote it when the primary Region becomes unavailable.

Answer

Deploy the Aurora cluster as Multi-AZ across us-east-1 Availability Zones and rely on automatic failover to another AZ.
