Ubuntu VPS: First-pass setup

A small series on baseline setup for Ubuntu VPS before deploying web applications. Focuses on practical steps I use every time I provision a new server: non-root user, SSH keys, firewall, automatic security updates, and other basics that are easy to miss. This is not a complete hardening guide or security audit, just a starting point I consider mandatory before installing the app stack.
