What versions of Linux operating system have you used in your practice?

In practice, various Linux distributions are often used depending on the tasks and environment. Here are some common versions I have worked with:

• Ubuntu (e.g., 18.04 LTS, 20.04 LTS) — popular for servers and workstations, has a large community and many packages.
• CentOS / AlmaLinux / Rocky Linux (7, 8) — widely used in corporate environments, especially for servers.
• Debian (9, 10, 11) — a stable distribution, often used for server solutions.
• Fedora — for newer versions of software and testing.

Each of these distributions has its own features in package management, system services, and configurations, which is important to consider when working in DevOps.
