Which AWS Well-Architected Framework pillar is focused on ensuring that workloads perform their functions and can rapidly recover from failures?

The Reliability pillar of the AWS Well-Architected Framework focuses on ensuring a workload performs its intended function correctly and consistently, and can recover from infrastructure or service disruptions. This includes designing highly available systems, implementing robust backup and recovery strategies, and managing change effectively to minimize impact. Performance efficiency focuses on using computing resources efficiently to meet system requirements and maintaining that efficiency as demand changes. Sustainability focuses on minimizing the environmental impacts of running cloud workloads. Security focuses on protecting information, systems, and assets. While all pillars are important, only Reliability directly addresses the ability to recover from failures and maintain consistent functionality.
