Amazon Application Recovery Controller (Route 53 ARC)
Explore how Amazon Application Recovery Controller (Route 53 ARC) improves disaster recovery by validating readiness before failover and enabling controlled, auditable traffic shifts. Understand the importance of readiness checks, controlled routing state transitions, and the limitations of routing control during multi-region failures to reduce recovery risks.
Amazon Application Recovery Controller (Route 53 ARC) is a control plane for disaster recovery readiness and controlled traffic shifting. It sits alongside Route 53 and the application endpoints it protects, answering one hard question in a drill or an incident: what must already be true before the button gets pressed that moves users to the standby stack.
ARC is not in the data path. Client traffic still goes through DNS answers from Route 53 to whatever regional endpoints are published, and application health still comes from the signals those endpoints emit. ARC adds two capabilities that change outcomes under pressure. It allows validating readiness ahead of time, and it provides controlled recovery actions, so a failover is deliberate rather than ... ...
