Amazon Application Recovery Controller (ARC)
#82 · Level 2 · Scaling and resilience · Monitoring and operationsConcept
Section titled “Concept”Amazon Application Recovery Controller (ARC) helps move an app’s traffic in a controlled way during trouble. Its zonal shift lets you temporarily move traffic away from an Availability Zone that is having problems to another AZ. Routing control is like an on-off switch for moving traffic between multiple Regions, and it works with Route 53 health checks. It also has features for planning a full Region switch. The main idea is to fail over safely along a path prepared in advance, instead of changing many settings by hand in a moment of crisis.
