Linux
Linux is a free, open-source operating system kernel that powers everything from personal computers to servers, smartphones, and cloud infrastructure. Most web servers, containers, and DevOps tooling run on Linux — making it an essential skill for any developer or engineer.
Why Linux?
- Ubiquitous in server environments — the majority of production servers run Linux
- Core of containerization — Docker and Kubernetes rely on Linux kernel features like namespaces and cgroups
- Powerful CLI — the shell lets you automate, script, and manage systems efficiently
- Free and open-source — no licensing costs, massive community support
