• Question 642:

  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?

  A. Standard Reserved Instances
  B. Convertible Reserved Instances
  C. On-Demand Capacity Reservations
  D. On-Demand Instances
  D. On-Demand Instances

  ---

  Explanation

  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.
