CLF-C02 Question 281
Single answerA startup is evaluating different AWS pricing models to minimize their infrastructure costs. Their workload is unpredictable with occasional traffic spikes, and they do not want to commit to long-term contracts. Which AWS pricing model would be most suitable for their needs?
- 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 best choice for workloads with unpredictable traffic spikes and no desire for long-term commitments. They allow the startup to scale up and down as needed and only pay for what they use, without any upfront costs or commitments.
- A. Correct.
On-Demand Instances are ideal for unpredictable workloads with no long-term commitment, as they allow the startup to pay for compute capacity by the hour or second.
- B. Incorrect.
Reserved Instances require a commitment of 1 or 3 years, making them less suitable for unpredictable workloads.
- C. Incorrect.
Spot Instances offer the lowest cost but are best suited for flexible workloads that can tolerate interruptions, which may not work well for unpredictable spikes.
- D. Incorrect.
Savings Plans require a commitment to a consistent usage level over time, which does not align with the startup's unpredictable workload.
