A company is running a multi-tier ecommerce web application in the AWS Cloud. The application runs on Amazon EC2 Instances with an Amazon RDS MySQLMulti-AZ DB instance. Amazon RDS is configured with the latest generation instance with 2,000 GB of storage in an Amazon Elastic Block Store (Amazon EBS)General Purpose SSD (gp2) volume. The database performance impacts the application during periods of high demand.
After analyzing the logs in Amazon CloudWatch Logs, a database administrator finds that the application performance always degrades when the number of read and write IOPS is higher than 6.000.
What should a solutions architect do to improve the application performance?
