Topic 1 Question 124
A company has a highly dynamic batch processing job that uses many Amazon EC2 instances to complete it. The job is stateless in nature, can be started and stopped at any given time with no negative impact, and typically takes upwards of 60 minutes total to complete. The company has asked a solutions architect to design a scalable and cost-effective solution that meets the requirements of the job. What should the solutions architect recommend?
Implement EC2 Spot Instances.
Purchase EC2 Reserved Instances.
Implement EC2 On-Demand Instances.
Implement the processing on AWS Lambda.

The correct answer is Option A. To design a scalable and cost-effective solution for the batch processing job, the solutions architect should recommend implementing EC2 Spot Instances.
EC2 Spot Instances allow users to bid on spare Amazon EC2 computing capacity and can be a cost-effective solution for stateless, interruptible workloads that can be started and stopped at any time. Since the batch processing job is stateless, can be started and stopped at any time, and typically takes upwards of 60 minutes to complete, EC2 Spot Instances would be a good fit for this workload.
