A company is running a reporting web server application on Amazon EC2 instances. The application runs once every week and once again at the end of the month. The EC2 instances can be shut down when they are not in use.

What is the MOST cost-effective billing model for this use case?

Show Suggested Answer Hide Answer
Suggested Answer: D

For a reporting application that runs only periodically, On-Demand Instances are the most cost-effective choice because they allow the company to pay only for the compute capacity used, without long-term commitments. Reserved Instances are less flexible due to the need for upfront payment or long-term contracts, which would not be cost-effective given the application's intermittent usage. On-Demand Capacity Reservations would also be more costly, as they hold capacity regardless of usage.

I think D is the best choice. Only running weekly, so why commit?

Standard Reserved Instances could be a good option if they plan to use it long-term.

Wait, can you really shut down EC2 and not get charged?

Definitely On-Demand Instances, they only pay for what they use.

On-Demand seems right since they only run weekly.

No way, Reserved Instances are way too expensive for this.

I’m a bit confused about the differences between the Reserved Instances options. Wouldn't Standard Reserved Instances lock us into a longer commitment?

This question reminds me of a practice one where we discussed the cost benefits of shutting down instances. I think On-Demand is still the way to go.

I remember studying Reserved Instances, but I feel like they might not be cost-effective for such infrequent use.

I think the On-Demand Instances might be the best option since the application only runs weekly and monthly, but I'm not completely sure.
