A company is currently running a production workload on AWS that is very I/O intensive. Its workload consists of a single tier with 10 c4.8xlarge instances, each with 2 TB gp2 volumes.

For the application to perform efficiently, they need to increase the IOPS by 3,000 for each of the instances. Which of the following designs will meet the performance goal MOST cost effectively?
