Question

A Solutions Architect notices slower response times from an application. The CloudWatch metrics on the MySQL RDS indicate Read IOPS are high and fluctuate significantly when the database is under load. How should the database environment be re-designed to resolve the IOPS fluctuation?

Answer 1

Change the storage type to the Provisioned IOPS is correct answer.

Step-by-step explanation:

Because the Architect observes that the following application response time is slower. And the CloudWatch metrics on RDS that shows the Read IOPS are huge and it also fluctuates automatically when the DB is under-load. So, That' why he has to change the storage type to the provisioned IOPS(Input/Output Operations Per Seconds).
