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.
