Linux

February 14, 2025

Linux powers the vast majority of servers, cloud instances, containers, and embedded systems. Whether you’re deploying a web application, configuring a reverse proxy, or hardening a production host, understanding Linux is foundational for DevOps.

Why Linux matters in DevOps

  • Dominance in production — Most web servers, Kubernetes nodes, and cloud VMs run Linux
  • Automation-friendly — Scripting, SSH, and config management (Ansible, Puppet) are first-class
  • Web servers & reverse proxies — Nginx, Traefik, Caddy, and Apache run natively on Linux
  • Cost and flexibility — No licensing fees; tailor the stack to your needs

What we cover

Our Linux tutorials focus on web servers and reverse proxies: Nginx for high-performance static sites and load balancing, Traefik for dynamic routing and Let’s Encrypt, and Caddy for automatic HTTPS with minimal config. You’ll find step-by-step setup guides, TLS configuration, and how these fit into a complete DevOps stack.
