A company needs to reduce the cost of its Amazon EC2 instances. The company also changes the instance type and instance family every 2–3 months. What should the company do to meet these requirements?

A No Upfront Compute Savings Plan offers significant cost savings (up to 66%) compared to On-Demand pricing, making it suitable for cost reduction. It provides the flexibility to change instance families, instance types, and even AWS Regions, which aligns with the company's need to change instance types and families every 2-3 months. The 1-year term is appropriate for this dynamic usage pattern. Partial Upfront Reserved Instances for a 3-year term would lock the company into a specific instance family and type, which doesn't meet the flexibility requirement, and the 3-year term is too long given the frequent changes. All Upfront Reserved Instances for a 1-year term also lack the necessary flexibility. All Upfront EC2 Instance Savings Plans offer flexibility for instance families and types, but the "All Upfront" payment model might not be preferred, and the Compute Savings Plan offers broader flexibility across compute services, making it a better fit here.
