Question

A DevOps engineer is researching the least expensive way to implement an image batch processing cluster on AWS. The application cannot run in Docker containers and must run on Amazon EC2. The batch job stores checkpoint data on an NFS volume and can tolerate interruptions. Configuring the cluster software from a generic EC2 Linux image takes 30 minutes. What is the MOST cost-effective solution?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Use Amazon EFS for checkpoint data. Use EC2 Fleet to launch EC2 Spot Instances. Create a custom AMI for the cluster and use the latest AMI when creating instances. EC2 Spot Instances use spare capacity at a large discount, ideal for fault-tolerant or flexible workloads. Spot Instances use spare capacity at a large discount, ideal for fault-tolerant or interruptible workloads. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. This option delivers the requirement at the lowest cost.
