AWS – Amazon RDS for DB2 now supports cross region standby replicas

Amazon Relational Database Service (RDS) for DB2 now supports cross-region standby replicas, a new feature that helps customers reduce database down time during disaster recovery. In situations where a database in a region becomes unavailable, customers can immediately promote a standby replica in a different region to resume operations, and do not have to wait until a database backup is restored.

To use the feature, customers simply configure their RDS for DB2 database instance to maintain a standby replica in another AWS region. RDS automatically replicates changes asynchronously from the primary instance to the standby replica. In situations where the primary database instance becomes unavailable, customers can promote the standby replica to primary, and resume read and write operations. Customers can create up to three standby replicas for a database instance. Since standby replicas are not operable until promoted, customers need commercial database licenses for only two vCPUs per replica, regardless of the number of vCPUs on the instance. Customers can use either Bring Your Own License (BYOL) or Marketplace licensing models to use Amazon RDS for DB2 with standby replicas.
