CLF-C02 Question 283
Single answerYour company is running a web application with consistent, predictable traffic patterns. The application needs to run 24/7, and cost optimization is a priority. Which compute purchasing option is most suitable in this scenario?
- A
On-Demand Instances
- B
Spot Instances
- C
Reserved Instances
- D
Savings Plans
Show answer and explanation
Correct answer: C
Explanation
Reserved Instances are the best fit for this scenario because they are designed for applications with predictable and consistent usage, such as a 24/7 web application. By committing to a long-term usage plan, Reserved Instances offer significant cost savings over On-Demand Instances. While Spot Instances and Savings Plans provide cost optimization in certain scenarios, they are not as suitable in this particular case due to the 24/7 availability requirement and the predictability of the workload.
- A. Incorrect.
On-Demand Instances are best suited for applications with unpredictable workloads or short-term use cases. While they offer flexibility, they are not the most cost-effective choice for predictable, 24/7 workloads.
- B. Incorrect.
Spot Instances provide significant cost savings but are suitable for workloads that can tolerate interruptions. They are not ideal for applications requiring 24/7 availability.
- C. Correct.
Reserved Instances are a cost-effective option for applications with predictable, steady-state usage. By committing to a 1-year or 3-year term, you can achieve significant savings compared to On-Demand pricing, making them ideal for this scenario.
- D. Incorrect.
Savings Plans also offer cost savings but are generally more flexible as they allow you to commit to a consistent amount of usage across instance families, but Reserved Instances are more directly tied to specific predictable workloads.
