Which AWS pricing commitment offers the most flexibility while still discounting on-demand pricing — applicable across EC2 instance families, sizes, OS, and Regions?
AStandard Reserved Instances tied to a specific instance type
BCompute Savings Plans
CSpot Instances
DDedicated Hosts
Answer & Solution
Correct answer: B. Compute Savings Plans
Compute Savings Plans give the broadest flexibility (any region, any family, any OS, even Lambda & Fargate) for a 1- or 3-year commitment. Standard RIs are narrower; Dedicated Hosts are billed per host; Spot is interruptible.
