Scaling Backend Infrastructure: Deploying Node.js 22 & PM2 on Dedicated Hardware

Hello Steemit tech community! 💻

If you are building decentralized applications, heavy web platforms, or high-traffic APIs, you know that shared hosting simply doesn't cut it. Moving to a dedicated server provides raw power, but configuring the software layer is where many developers get stuck.

Because Node.js runs on a single thread, deploying it raw on a 16-core dedicated server means 15 of those cores are asleep. We've written a complete guide on how to fix this using PM2.

In this tutorial, we cover:

Installing Node.js 22 LTS safely via the NodeSource repository.

Configuring PM2 Cluster Mode to spawn workers across every CPU core.

Generating Systemd Startup Scripts so your server recovers from hard reboots instantly.

Setting up Nginx as a reverse proxy to manage web traffic.

This is the exact stack used by enterprise applications to achieve zero-downtime and maximum hardware utilization.
