SAP-C02 Question 135
Single answerA company runs a fleet of Amazon EC2 instances for a workload that has consistent, predictable usage for at least the next 12 months. The company wants to minimize costs while maintaining the ability to change instance families if necessary. Which purchasing option meets these requirements?
- A
On-Demand Instances
- B
Standard Reserved Instances
- C
Spot Instances
- D
Compute Savings Plans
Show answer and explanation
Correct answer: D
Explanation
Compute Savings Plans are the best option because they provide cost savings similar to Reserved Instances for predictable workloads while offering the flexibility to switch between instance families, sizes, and regions if needed. This aligns with the company's requirements of minimizing costs and maintaining flexibility.
- A. Incorrect.
On-Demand Instances are suitable for unpredictable or short-term workloads but are the most expensive option for consistent, long-term usage. They don't provide cost savings for predictable workloads.
- B. Incorrect.
Standard Reserved Instances provide significant cost savings for predictable workloads but lack flexibility in changing instance families, making them unsuitable if instance families may need to change.
- C. Incorrect.
Spot Instances are highly cost-effective but are not ideal for workloads requiring consistency and predictability, as they can be interrupted with little notice.
- D. Correct.
Compute Savings Plans offer significant cost savings for consistent, predictable workloads and provide flexibility to change instance families, sizes, and even regions, making them the best choice for this scenario.
