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.

Today, AWS announces the open sourcing of pgactive, a PostgreSQL extension for active-active replication. pgactive lets you use asynchronous active-active replication for streaming data between database instances to provide additional resiliency and flexibility in moving data between database instances, including writers located in different regions. This helps maintain availability for operations like switching write traffic to a different instance.

pgactive builds on the foundation PostgreSQL logical replication features, such as bidirectional replication between tables starting in PostgreSQL 16, adding capabilities that simplify managing active-active replication scenarios. Open sourcing the pgactive extension allows for more collaboration on developing active-active capabilities of PostgreSQL, while offering features that simplify using PostgreSQL in scenarios that benefit from multiple active instances.

To learn more about pgactive and how to get started, visit the GitHub repository.
