Red Hat Enterprise Linux running GNOME desktop environment

Red Hat Linux Download

Red Hat Enterprise Linux is a commercial Linux distribution built for powering the servers of corporations and data centers. It’s a robust distro with the features and stability that businesses crave for high availability and predictability.

The big appeal of Red Hat, though, is its support system. That’s the main thing you’re paying for, after all. If something doesn’t operate as expected, businesses want someone to turn to for support so they can face as little downtime as possible. Red Hat experts are only a phone call away for subscribers.

The support feature is what really sets Red Hat apart from other Linux distributions that could also perform the same job very well, such as CentOS, Fedora, and OpenSUSE. For other most popular Linux distributions please visit our dedicated linux download page.

Red Hat offers training and certification programs to prospective Linux system administrators. This is another big plus for businesses, as they can buy training for their employees or vet new recruits by their certifications. Such training and certifications are rare to find in the Linux world, being that Linux distros are mostly free and run by a community of volunteers.

If you are a system administrator looking to get into Red Hat, most or all of your experience with CentOS and Fedora Server should transfer over to Red Hat, since the three distributions are closely related.

Arch Linux running KDE desktop manager

Arch Linux Download

Arch Linux is an independently developed Linux distribution geared towards experienced Linux users. Its main aim is on simplicity and minimalism.

If you’re brand new to Linux, Ubuntu and Linux Mint are designed to give you an easier introduction. For other most popular Linux distributions please visit our dedicated linux download page.

Manjaro is based on Arch Linux, taking its best features and adding a dash of user friendliness. It’s a good distro to check out if you appreciate Arch’s ideals but are a little intimidated by the complexity of configuring things from the ground up.
