SAP-C02 Question 528
Single answerA company is running multiple EC2 instances in their production environment. Their usage patterns show consistent compute demand for the next three years. The company wants to optimize costs while maintaining flexibility to change instance families or sizes in the future if needed. Which pricing model should the company adopt?
- A
On-Demand Instances
- B
Spot Instances
- C
Reserved Instances (Standard)
- D
Savings Plans
Show answer and explanation
Correct answer: D
Explanation
Savings Plans are an excellent choice for workloads with predictable and consistent usage patterns, as they provide significant cost savings while allowing flexibility to switch between instance families, sizes, and regions. This makes them more adaptable compared to Standard Reserved Instances, which are rigid in nature. On-Demand and Spot Instances do not align with the company's cost optimization goals and usage patterns.
- A. Incorrect.
On-Demand Instances provide maximum flexibility but are the most expensive pricing model, making them unsuitable for workloads with consistent usage patterns.
- B. Incorrect.
Spot Instances are highly cost-effective but are not suitable for workloads with consistent and predictable compute demand, as they can be interrupted by AWS at any time.
- C. Incorrect.
Reserved Instances (Standard) can provide significant cost savings, but they lack flexibility to change instance families or sizes, which the company requires.
- D. Correct.
Savings Plans offer cost savings similar to Reserved Instances while allowing flexibility to change instance families, sizes, and even regions, making them the best choice for consistent yet adaptable workloads.
