description Overview

PM2-cluster

PM2-cluster is an extension of PM2 designed specifically to utilize all available CPU cores for Node.js applications. It automatically manages worker processes, ensuring that if one worker crashes, the others continue serving traffic while the failed one is restarted. This is crucial for maximizing throughput and maintaining uptime under heavy load for JS backends.

PM2-forever

PM2-forever is a simpler, older utility within the PM2 ecosystem focused purely on keeping processes alive indefinitely. If your only requirement is 'if it dies, restart it immediately,' and you are using Node.js, this tool provides that functionality with minimal configuration overhead. It is less feature-rich than the full PM2 suite but highly effective for basic uptime guarantees.
