What should the company do to meet these requirements?
Purchase a Compute Savings Plan that is based on Savings Plans recommendations
Purchase an EC2 Instance Savings Plan that covers the EC2 instance types and the Fargate and Lambda vCPU equivalents.
Purchase a Reserved Instance for the instance types, operating systems, Region, and tenancy,
Use EC2 Spot Instances that match the type and size of existing instances that run in each Region.
Explanations:
The Compute Savings Plan offers cost savings across EC2, Fargate, and Lambda, regardless of instance family, Region, or OS, providing flexibility for the company’s diverse infrastructure and cross-region operations.
The EC2 Instance Savings Plan is limited to specific EC2 instance types, and does not fully cover Fargate and Lambda in the same flexible manner, thus lacking the required flexibility across the company’s varied workloads.
Reserved Instances apply only to specific instance types, Regions, operating systems, and tenancy, restricting the company from making changes as needed and not covering Fargate and Lambda, so it lacks the flexibility required.
Spot Instances provide cost savings but do not guarantee availability since they are interruptible, making them unsuitable for the company’s requirement for a 24/7 always-on core application that needs high reliability.
I evaluate that the answer is:
Purchase a Compute Savings Plan that is based on Savings Plans recommendations
