Automating cross-account refresh for Amazon RDS Multi-AZ DB clusters

Amazon RDS Multi-AZ DB clusters don't support cross-account snapshot sharing, but this post presents a serverless workaround using AWS Lambda, Step Functions, and EventBridge. The pipeline automates environment refresh across two AWS accounts in seven steps: creating a cluster snapshot, restoring it to a temporary single-AZ instance, creating a shareable instance snapshot, sharing it cross-account, cleaning up the temporary instance, copying and re-encrypting the snapshot in the destination account, and finally restoring it as a Multi-AZ DB cluster. The solution is deployed via CloudFormation templates and triggered with a single CLI command. Extensions include scheduled refreshes via EventBridge Scheduler and data masking for non-production environments.
