Which design principle of the Reliability pillar in the AWS Well-Architected Framework helps a workload achieve high availability by detecting problems and returning to a healthy state without human intervention?
Manage change through automation
Automatically recover from failure
Stop guessing capacity
Enable traceability
Automatically recovering from failure means a workload continuously monitors key performance indicators and initiates self-healing actions-such as restarting instances or shifting traffic-whenever thresholds are breached. This minimizes downtime and maintains availability. The other choices are also Well-Architected principles, but they address capacity planning, change management, or security rather than automatic fault recovery.
