Which solution will meet these requirements MOST cost-effectively?

Compute Savings Plan

EC2 Instance Savings Plan

Zonal Reserved Instances

Standard Reserved Instances

Explanations:

Compute Savings Plan offers flexibility to switch instance families, sizes, and even across EC2, Fargate, and Lambda, making it cost-effective for changing needs.

EC2 Instance Savings Plan restricts flexibility to a specific instance family within a region, which does not meet the requirement to switch instance families.

Zonal Reserved Instances are specific to an instance type and availability zone, limiting flexibility and not ideal for changing instance families or sizes.

Standard Reserved Instances are also limited to specific instance families and sizes, reducing flexibility and adaptability to changing application needs.
