Question
Application developers have reported that an application is running slower as more users are added. The application database is running on an Amazon Aurora DB cluster with an Aurora Replica. The application is written to take advantage of read scaling through reader endpoints. A database specialist looks at the performance metrics of the database and determines that, as new users were added to the database, the primary instance CPU utilization steadily increased while the Aurora Replica CPU utilization remained steady. How can the database specialist improve database performance while ensuring minimal downtime?
