Short Explanation
Rightsizing is like canceling the unused gym membership and swapping the oversized truck for one that fits the job. Cost Optimization is the pillar that pushes teams to remove unused spend and match capacity to need. Reliability keeps things available, Operational Excellence improves how you run them, and Security protects them — none of those is the rightsizing-and-waste pillar.

Reliability emphasizes resilience and recovery, Operational Excellence emphasizes operating and improving processes, and Security emphasizes protective controls.
