AWS developers can now enhance their database resilience with an automated RDS snapshot and cross-region disaster recovery solution. This open-source repository provides a codebase and documentation for implementing this architecture, which leverages AWS Lambda functions and EventBridge rules to create regular snapshots in the US East (N. Virginia) region and copy them to the US West (Oregon) region for disaster recovery purposes. The system also includes a mechanism to clean up old snapshots, ensuring efficient resource management.
