Which pillar of the AWS Well-Architected Framework does this ability represent?

Explanations:

Cost optimization focuses on managing costs and maximizing the return on investment, rather than on infrastructure recovery capabilities.

Performance efficiency involves the ability to use computing resources efficiently to meet system requirements, which does not directly relate to disaster recovery.

Reliability pertains to a system’s ability to recover from failures and continue to function as intended, which includes strategies for disaster recovery and maintaining infrastructure during adverse conditions.

Security is concerned with protecting data, systems, and assets against unauthorized access and attacks, rather than specifically focusing on infrastructure recovery in the event of natural disasters.
