Introduction If you’ve worked in production long enough, you’ve probably heard this: “Let’s right-size the services and reduce the AWS bill.” So we do it. We check CPU and memory metrics for a week.

Is the garbage collection process busy? Are we slowly moving towards an OOM error? Without oversight, you’re essentially flying blind. In this guide, […]
