Amazon Application Recovery Controller’s Region switch feature now supports post-recovery workflows that automate tasks following failover or failback, such as scaling resources and recreating read replicas. It includes execution blocks for Lambda functions, Amazon RDS replica creation, manual approvals, and nested recovery plans, enabling comprehensive recovery orchestration beyond initial failover.
The update also introduces native Amazon RDS execution blocks for promoting read replicas and creating replicas during orchestration, reducing manual errors and delays. Further, AWS provider support for Terraform allows users to manage disaster recovery plans as code within CI/CD pipelines, streamlining infrastructure automation and compliance.
