You plan on hosting an application on EC2 Instances which will be used to
process logs. The application is not very critical and can resume operation even after an interruption. Which of the following steps can help provide a cost-effective
solution?
A. Use Reserved Instances for the underlying EC2 Instances.
B. Use Provisioned IOPS for the underlying EBS Volumes.
C. Use Spot Instances for the underlying EC2 Instances.
D. Use S3 as the underlying data layer.
Explanation:
Answer – C
One effective solution would be to use Spot
Instances in this scenario.
AWS Documentation mentions
the following on Spot Instances:
Spot Instances are a cost-effective choice
if you can be flexible about when your applications run and if your
applications can be interrupted. For example, Spot Instances are well-suited
for data analysis, batch jobs, background processing, and optional tasks.
