Popular Linux Distributions

Imagine Linux as a powerful engine that runs a computer, but on its own, it's just a bare-bones skeleton. That's where Linux distributions come in. They take that raw power of the Linux kernel and dress it up with a complete operating system.

As this course primarily targets server infrastructure, our main concentration will be on server-based distros, excluding client distros like Ubuntu Desktop.

A Linux distribution, also known as a distro, is like a full package deal. It includes the Linux kernel, which is the brain behind the scenes that talks to the hardware and manages system resources. But that's not all! It also bundles together a whole bunch of software components like libraries, utilities, applications, and sometimes a graphical user interface (GUI) to make your life easier.

Think of it as a customized flavor of Linux. Each distribution has its own personality, preferences, and goals. It's like a different recipe cooked up by different chefs.

Below is a list of popular Linux distros. The "best" Linux distribution topic is a hotly debated one and not one we are making an argument for.

• Ubuntu Server
• AlmaLinux (similar to RHEL and CentOS)
• Debian Linux
• Fedora Server
• ArchLinux
• openSUSE

Choosing the right Linux distribution for your specific needs is a complex decision. It depends on various factors, such as your (or your team's) prior Linux experience or simply personal preference. To help you make an informed choice, consider the following key factors that differentiate Linux distributions:

1. Package Management System
2. Software Repository
3. Default Desktop Environment
4. Release Model

Let's look into each of these in more detail.
