AWS Certified Cloud Practitioner (CLF-C02) — Question 431
A company's application is running on Amazon EC2 instances. The company is planning a partial migration to a serverless architecture in the next year and wants to pay for resources up front.
Which AWS purchasing option will optimize the company's costs?
Answer options
- A. Convertible Reserved Instances
- B. Spot Instances
- C. EC2 Instance Savings Plans
- D. Compute Savings Plan
Correct answer: D
Explanation
Compute Savings Plans provide the highest flexibility by automatically applying to compute usage across Amazon EC2, AWS Fargate, and AWS Lambda, which perfectly accommodates a transition to serverless. EC2 Instance Savings Plans and Convertible Reserved Instances are restricted to EC2 instances and cannot be applied to serverless compute services. Spot Instances are designed for fault-tolerant workloads and do not support upfront payment commitments for consistent workloads.
