• Question 423:

  A company has developed a distributed application that recovers gracefully from Interruptions. The application periodically processes large volumes of data by using multiple Amazon EC2 Instances. The application is sometimes idle for months.

  Which EC2 instance purchasing option is MOST cost-effective for this use case?

  A. Reserved Instances

  B. Spot Instances

  C. Dedicated Instances

  D. On-Demand Instances

  Correct Answer: B

  B. Spot instances.

  Since the application is sometimes idle for months, spot instances are the most cost-effective option for this use case. Spot instances allow users to bid on unused EC2 capacity, and the price is determined by supply and demand. When

  demand for EC2 capacity increases, the spot instance price goes up, and when demand decreases, the spot instance price goes down. This makes spot instances ideal for workloads that are flexible and can be interrupted, such as batch

  processing jobs, data analysis, and testing environments. Since the application can recover gracefully from interruptions, spot instances are a cost- effective option that can save the company money when the instances are available.
