Choosing a Linux Distro

3 minute read

With hundreds of Linux distributions available, picking the right one feels overwhelming. The good news: for most people learning Linux, the choice is simple. But understanding why different distros exist helps you make smarter decisions throughout your career.

The Short Answer

Your Goal Use This
Learning Linux for the first time Ubuntu 22.04 LTS
Preparing for RHCSA certification Rocky Linux 9
Running Docker containers Alpine Linux
Cutting-edge desktop Linux Fedora
Enterprise production servers RHEL or Rocky Linux
Deep Linux customization Arch Linux

For this tutorial series, we use Ubuntu 22.04 LTS throughout.

Ubuntu / Debian Family

Ubuntu is the most popular Linux distro for beginners, cloud, and general server use.

✅ Pros:
  - Massive community — answers to every question exist on Stack Overflow
  - apt package manager — easy to install software
  - LTS releases (5 years of security updates)
  - Default on AWS, GCP, Azure Marketplace
  - Best documentation for beginners

⚠️  Cons:
  - Not used in traditional enterprise environments
  - Slightly heavier than minimal distros

Package manager: apt Release model: Regular releases every 6 months + LTS every 2 years Example: Ubuntu 22.04 LTS (supported until April 2027)

# Install a package on Ubuntu/Debian
sudo apt update && sudo apt install curl -y

CentOS Stream / Rocky Linux / RHEL

Red Hat Enterprise Linux (RHEL) is the gold standard for enterprise Linux. Rocky Linux is a free, community rebuild of RHEL — perfect for learning enterprise Linux without paying for a RHEL subscription.

✅ Pros:
  - Industry standard for enterprise environments
  - RHCSA/RHCE certification target
  - Long support cycles (10 years)
  - SELinux enforced by default (security hardening)

⚠️  Cons:
  - Less beginner-friendly (smaller community than Ubuntu)
  - Older package versions in default repos
  - CentOS 7/8 is EOL — use Rocky Linux 9

Package manager: yum (older) / dnf (current standard) Release model: Major releases (RHEL 8, RHEL 9)

# Install a package on Rocky/RHEL/CentOS
sudo dnf install curl -y

Arch Linux

Arch is a rolling release distro — you always have the latest version of every package. It is minimal by design: you start with a bare system and build exactly what you want.

✅ Pros:
  - Always up-to-date packages
  - Excellent Arch Wiki (the best Linux documentation anywhere)
  - Deep understanding of Linux — you build everything yourself
  - Lightweight (only install what you need)

⚠️  Cons:
  - No graphical installer — installation is entirely command-line
  - Can break after updates (rolling release risk)
  - Not recommended for beginners or production servers

Package manager: pacman Release model: Rolling (continuous updates)

# Install a package on Arch
sudo pacman -S curl

Alpine Linux

Alpine is designed for containers and embedded systems. Its entire base image is ~5MB — compared to Ubuntu’s ~29MB. It uses musl libc instead of glibc, which occasionally causes compatibility issues with some software.

✅ Pros:
  - Tiny footprint — ideal for Docker base images
  - Security-focused (runs as non-root by default, minimal attack surface)
  - Fast to pull and start in containers

⚠️  Cons:
  - Not GNU/Linux — uses musl libc and BusyBox instead of GNU tools
  - Some packages behave differently from Ubuntu
  - Not suitable as a primary learning distro (too minimal)

Package manager: apk Typical use: FROM alpine:3.19 in Dockerfiles

# Install a package on Alpine
apk add curl

Comparison Table

Distro Package Mgr Base Target User Release Model Docker Size
Ubuntu 22.04 LTS apt Debian Beginners, cloud, general LTS + regular ~29MB
Debian 12 apt Itself Stability-focused servers Stable ~27MB
Rocky Linux 9 dnf RHEL Enterprise, RHCSA learners Major releases ~66MB
Fedora 39 dnf RHEL upstream Developers, latest features 6-month cycle ~64MB
Arch Linux pacman Itself Advanced users Rolling ~65MB
Alpine 3.19 apk Itself Containers, minimal Rolling ~5MB

Which Distro Does This Tutorial Use?

Ubuntu 22.04 LTS — for every command, example, and walkthrough in this series.

Why:

  • Default cloud VM on AWS, GCP, and Azure
  • Best beginner experience
  • All commands are directly transferable to production cloud environments
  • Where you will run your first real server
