An auditor asks how the Reliability pillar differs from the Security pillar in the AWS Well-Architected Framework. Which contrast is accurate?
Select an answer to reveal the explanation.
Short Explanation
One pillar is the spare tire and recovery plan; the other is the lock on the doors. Reliability is about keeping workloads working and recovering from failures; Security is about protecting data and access. They work together in a good design, but they are not the same checklist.
Full Explanation
Reliability addresses a workload’s ability to perform its intended function correctly and consistently, including recovery from infrastructure or service disruptions and designs that support availability targets. Security addresses protecting information and systems through identity, detection, infrastructure protection, data protection such as encryption, and incident response. They are separate Well-Architected pillars; password policy alone is not the full Reliability story, Auto Scaling is not Security’s sole concern, and neither pillar is defined as electricity use or monthly bill reduction.
