A city council slide lists "encrypt everything" under the Cost Optimization pillar of the AWS Well-Architected Framework. Which pillar should that concern be moved to?
Select an answer to reveal the explanation.
Short Explanation
Encrypting data is a lock-and-key story, not a coupon story. Security is the pillar that covers protecting data with encryption, identity, and related controls; Cost Optimization is about spend efficiency and waste. Parking encryption under Cost Optimization mixes up the pillars, even though encryption choices can have cost side effects.
Full Explanation
In the AWS Well-Architected Framework, encryption at rest and in transit, identity controls, and related protective measures are Security pillar concerns. Cost Optimization addresses understanding spend, eliminating unused resources, and selecting cost-effective pricing models. Performance Efficiency, Reliability, and Sustainability address resource selection and scaling, failure handling, and environmental impact respectively. The slide should place "encrypt everything" under Security, not Cost Optimization.
