SAP-C02 Question 340
Single answerA company has a steady workload that runs 24/7 on Amazon EC2 instances. The team wants to optimize their costs while retaining flexibility to change instance families or regions if necessary. Which pricing model would best meet their requirements?
- A
On-Demand Instances
- B
Reserved Instances (Standard)
- C
Reserved Instances (Convertible)
- D
AWS Savings Plans
Show answer and explanation
Correct answer: D
Explanation
AWS Savings Plans are ideal for workloads with predictable usage patterns, such as a steady 24/7 workload, while offering more flexibility than Reserved Instances. Unlike Standard Reserved Instances, they allow changes across EC2 instance families, sizes, and regions, aligning perfectly with the company's requirement for cost optimization and flexibility.
- A. Incorrect.
On-Demand Instances provide maximum flexibility but are the most expensive option for workloads that run continuously. They are not cost-optimized for a steady 24/7 workload.
- B. Incorrect.
Standard Reserved Instances offer significant cost savings but lack flexibility to change instance families or regions without modifications, which does not meet the company's requirement for flexibility.
- C. Incorrect.
Convertible Reserved Instances allow for some flexibility (such as changing instance families or sizes) but are still tied to specific EC2 instance usage, making them less flexible than Savings Plans.
- D. Correct.
AWS Savings Plans offer cost savings similar to Reserved Instances while providing flexibility to switch between instance families, sizes, operating systems, and even regions. This makes it the best choice for a steady 24/7 workload with a need for flexibility.
