Amazon RDS for Db2 now supports read replicas

Amazon Relational Database Service (RDS) for DB2 now supports read replicas. Customers can add up to three read replicas for their database instance, and use the replicas to support read-only applications without overloading the primary database instance.

Customers can setup replicas in the same region or in a different region from the primary database instance. When a read replica is setup, RDS replicates changes asynchronously to the read replicas. Customers can run their read-only queries against the read replica without impacting performance of the primary database instance. Customers can also use read replicas for disaster recovery procedures by promoting a read replica to support both read and write operations.

Read replicas require IBM Db2 licenses for all vCPUs on replica instances. Customers can obtain On-Demand Db2 licenses from the AWS Marketplace, or use Bring Your Own License (BYOL). To learn more, refer to Amazon RDS for Db2 documentation and pricing pages.
