Open SUSE Linux Enterprise Server OS
This Linux server OS is based on the open-source openSUSE Linux distro, formerly known as SUSE Linux. Open SUSE has two derivatives: Leap and Tumbleweed. For those who are looking for Linux server distribution with longer release cycles and stability, then Leap is meant for you. Tumbleweed, on the other hand, fashions rolling release with up-to-date packages such as Linux kernel and SAMBA, which is apt for power users.

Fedora is best for system administrators and experienced Linux developers. Download: Fedora (Free)
CentOS
CentOS is the acronym for Community Enterprise Operating System, and one of the best Linux Distro derived from Red Hat. In fact, it is a reasonable clone of the Red Hat Enterprise Linux(RHEL). The CentOS Linux distro aims to help users develop open source technologies on Linux servers. About 30 percent of overall Linux servers are operated on CentOS, the reason is the stability. Full updates are available for CentOS until the end of 2020, and the maintenance updates will be available until June 2024. Thus users are free from the hassle of upgrading in the near future.

The standard version of ClearOS, which was formerly known as ClarkConnect, has security enhancement features. This Linux server OS features intrusion detection, email server, firewall, and bandwidth management tools. ClearOS has its paid variants, but for the free version, users can rely on the Community Edition of ClearOS. The updates are also free but not tested. This Linux fashions an administration interface with high-level documentation, ideal for less-experienced administrators. Download: Clear OS (Freemium)
Arch Linux
Arch Linux is noticed for being a simple and lightweight OS. Like many other Linux distros, Arch Linux also consumes fewer resources than its counterparts. This lightweight Linux server distro properly allots resources to ensure maximum uptime and server efficiency. A pre-packaged server release is unavailable for Arch Linux, so users must create their own. The updates are rolling release models. You can use Pacman package manager to get the updates with full dependency tracking. Arch Linux is for that user with good technical knowledge to set up a server since a default server release is not provided. Download: Arch Linux (Free)
Slackware
Slackware is not a newbie in the server distro game, it has been in the game since 1993. This Linux Server OS features X Window System and several servers (email server, web server, news server, and FTP server). Slackware is another one of the Linux Servers to hold that lightweight tag when you talk about lightweight Linux servers. The updates of Slackware ensure simplicity and stability furthermore. Package managers such as pkgtools and slackpkg are featured by this Linux server distro. But then Slackware boots into command line interface implies that Slackware suits more advanced users who can work on command line interface. Download: Slackware (Free)
OpenSUSE Leap
OpenSUSE Leap is another great choice of linux for servers. It’s the standard OpenSUSE release known and preferred for its stability. Leap uses a source from SUSE Linux Enterprise (SLE), another great choice already mentioned on this list. That, in part, gives it the stability it’s known for. OpenSUSE is available for desktops, laptops as well as servers. OpenSUSE is also available as a rolling release in Tumbleweed, but that’s meant mostly for PCs. The cloud-agnostic design gives you more freedom and has multimode architecture. OpenSUSE is one of the very popular distros. As a result, it has a large online community that can be very helpful should you run into issues. There are no separate ISOs available for servers. However, the default installer does provide the option for server installation. Download: OpenSUSE Leap (Free)
Fedora CoreOS
Fedora CoreOS was previously known as Container Linux. This is the second Fedora labeled secure Linux distro for servers on this list. Fedora CoreOS differentiates itself, however, because it’s designed to run containers. Fedora CoreOS is an “automatically-updating, minimal operating system for running containerized workloads securely and at scale.” Red Hat acquired CoreOS in 2018 because of its container-optimized environment. For the uninitiated, Red Hat is also responsible for Fedora. Hence, Fedora CoreOS is Red Hat’s solution for container deployments. Fedora CoreOS ships pre-installed with both docker and podman.

Oracle Linux
Oracle Linux is compiled from the Red Hat Enterprise Linux source code and is open-source. As a result, it’s compatible with RHEL’s entire application library. It’s packaged and distributed by Oracle. This Linux server distro packs in many tools that make it suitable for memory management, file organization, and virtual environments and data systems. While the distro is free, Oracle does offer paid premium support, which makes it a direct competitor of RHEL. Oracle is optimized specifically for use with Oracle database and other Oracle products. It uses the Unbreakable Enterprise Kernel, a custom kernel built and optimized for Oracle software. Download: Oracle Linux (Freemium) There is a variety of Linux server distros available out there. Most of these Linux Distros are the best Linux server distros and perform well but are limited to certain users and businesses. Not all of these Linux server distros are for everyone. Each one of them is meant for different types of users who are targeting different business models. Understanding your use and expertise is important before choosing a server operating system. I hope the above list helps you get a sufficient server OS for your organization or home use. Fedora is base distro like Debian and Slackware. These are not based on any other OS. RedHat is “frozen” version of two Fedora releases. Ubuntu is derived from Debian to be commercial offering. CentOS is RedHat supported open sourceversion of RHEL and gives testinground dor development on Enterprise Linux without cost of lisensing. Fedora and Debian are comparable distros like RedHat and Ubuntu LTS. There are lots of good distros for home use but in business RH/C/F landscape gives least headaches.
