The moment an Ubuntu VPS gets a public IP, automated bots start knocking on port 22. Within hours you will see thousands of failed login attempts in your auth log — scripts cycling through root, admin, ubuntu, and a dictionary of weak passwords. SSH is the front door to your server, and the default configuration leaves …

A firewall decides which network ports on your VPS the outside world can reach. Without one, every service you start — a database, a stray dev server, a debugging tool — is exposed to the entire internet the instant it binds to a public interface. Ubuntu ships with UFW (Uncomplicated Firewall), a friendly front end to …

Hardening SSH with keys stops password attacks from succeeding, but the attempts keep coming — bots will hammer your server thousands of times a day regardless. Fail2ban turns that noise into action: it watches your log files, spots the pattern of repeated failures from a single IP, and tells the firewall to ban that …

Most services on a Linux VPS run with far more power than they need. A web app that only has to read its own files and listen on a port often runs able to write anywhere on the filesystem, see every other process's temp files, and acquire new privileges at will. If that service is ever compromised, all of that latent …

A small VPS — 1 or 2 GB of RAM, a couple of vCPUs — ships with kernel defaults tuned for a generic desktop or a large server, neither of which describes your box. A handful of sysctl and limit adjustments can make that same hardware noticeably more responsive under load: less needless swapping, more simultaneous …

Running a VPN on a VPS isn't just for privacy — it's useful for securing outbound traffic, routing through a different exit node for region-sensitive services, and building private networks between servers using NordVPN's Meshnet feature. This guide covers installing NordVPN on an Ubuntu 22.04 server, configuring it …

Shared hosting is a fine starting point. It's cheap, setup is simple, and someone else handles the server. But at some point, many sites outgrow it — and when they do, the experience gets frustrating fast. This guide explains how to recognize when you've hit that wall, what you actually gain by moving to a DigitalOcean …

A Droplet is what DigitalOcean calls a virtual private server — it's a Linux computer running in a data center that you control entirely. Once it's set up, you can host a website, run an app, store files, or use it as a development environment. You pay by the hour (or a flat monthly rate), and you can delete it the …

Ubuntu 22.04 LTS is the most widely supported Linux distribution for VPS workloads — it ships with a 5.15 kernel, full hardware enablement stack options, and security patches guaranteed through April 2027 on the standard LTS cycle (and longer with ESM). Virtually every major VPS provider lists it, but "supports Ubuntu …

Once you have a DigitalOcean Droplet running, the next thing most people want to do is put a website on it. This guide shows you how — step by step, in plain English. We'll install a web server called Nginx (pronounced "engine-X"), upload your site files, point your domain to the server, and turn on HTTPS. By the end, …
