CLF-C02 Question 280
Single answerA startup company is planning to deploy a web application on AWS but is unsure about future traffic demands. The company has a tight budget and wants to ensure cost efficiency while maintaining flexibility. Which AWS pricing model is the MOST suitable for their compute resources?
- A
On-Demand Instances
- B
Reserved Instances
- C
Spot Instances
- D
Savings Plans
Show answer and explanation
Correct answer: A
Explanation
On-Demand Instances are the most suitable pricing model for the startup because they provide the flexibility to scale compute resources up or down based on traffic demands without requiring long-term commitments or upfront payments. This aligns well with the company's budget constraints and need for flexibility in an unpredictable environment.
- A. Correct.
On-Demand Instances allow the company to pay for compute capacity by the hour or second without any long-term commitments, making it ideal for unpredictable workloads.
- B. Incorrect.
Reserved Instances provide significant cost savings for predictable workloads but require a long-term commitment, which is not suitable for the company's unpredictable traffic demands or budget constraints.
- C. Incorrect.
Spot Instances offer the lowest cost for compute resources but are not ideal for applications that require consistent availability, as they can be interrupted at short notice.
- D. Incorrect.
Savings Plans provide cost savings for predictable usage across services, but they require a commitment to a consistent usage level, which may not align with the company's unpredictable traffic and tight budget.
