Which pillar of the AWS Well-Architected Framework aligns with these goals?

Explanations:

Performance efficiency focuses on using resources efficiently to meet system requirements and can include factors like scaling and managing resource usage. While important, it does not primarily address failure recovery.

Sustainability in the AWS Well-Architected Framework refers to the environmental impact of workloads, emphasizing efficient use of resources and energy. This pillar does not relate to workload recovery or failure management.

Reliability is about ensuring workloads can perform their intended functions and recover quickly from failures. It emphasizes redundancy, failover mechanisms, and testing to maintain availability.

Security focuses on protecting data, systems, and assets from threats. While security is crucial for overall system integrity, it does not directly address the recovery of workloads after a failure.
