Summary
In this chapter, we have gone through the importance of having an APM tool as a part of your setup. We have installed the New Relic APM agent into our AWS EC2 instance and Docker container to start recording performance and usage data. Using an APM tool is entirely optional, but having one will help you and your team address issues more quickly by giving you and your team real production performance data. By having an APM tool, you will be able to understand your application much better, and it will help you to optimize and improve your application.
