A company wants commitment-based discounts on compute spend but needs flexibility to change instance families and even move workloads between EC2, Fargate, and Lambda. Which pricing model fits?
A.Standard Reserved Instances
Standard RIs are rigid — tied to instance family/tenancy and EC2 only.
B.Compute Savings Plans
Correct. Dollar-commitment flexibility across compute services.
C.Spot Instances
Spot is interruptible — not a commitment discount.
D.Dedicated Hosts
Dedicated Hosts are for licensing/compliance, not flexibility.
Why this answer
Savings Plans commit to a $/hour spend rather than specific instances — Compute SPs apply across EC2 families, regions, Fargate, and Lambda automatically. Standard RIs lock to instance attributes and don't cover Fargate/Lambda.
