Top Linux Server Distributions

You know that Linux is a hot data center server. You know it can save you money in licensing and maintenance costs. But that still leaves the question of what your best options are for Linux as a server operating system.

We have listed the top Linux Server distributions based on the following characteristics:

  1. Ease of installation and use
  2. Cost
  3. Available commercial support
  4. Data center reliability
Ubuntu LTS

Ubuntu

At the top of almost every Linux-related list, the Debian-based Ubuntu is in a class by itself. Canonical’s Ubuntu surpasses all other Linux server distributions — from its simple installation to its excellent hardware discovery to its world-class commercial support, Ubuntu sets a strong standard that is hard to match.

Ubuntu

The latest release of Ubuntu, Ubuntu 16.04 LTS “Xenial Xerus,” debuted in April 2016 and ups the ante with OpenStack Mitaka support, the LXD pure-container hypervisor, and Snappy, an optimized packaging system developed specifically for working with newer trends and technologies such as containers, mobile and the Internet of Things (IoT).

The LTS in Ubuntu 16.04 LTS stands for Long Term Support. The LTS versions are released every two years and include five years of commercial support for the Ubuntu Server edition.

Red Hat Enterprise Linux

Red Hat Enterprise Linux

While Red Hat started out as the “little Linux company that could,” its Red Hat Enterprise Linux (RHEL) server operating system is now a major force in the quest for data center rackspace. The Linux darling of large companies throughout the world, Red Hat’s innovations and non-stop support, including ten years of support for major releases, will keep you coming back for more.
Red Hat
RHEL is based on the community-driven Fedora, which Red Hat sponsors. Fedora is updated more frequently than RHEL and serves as more of a bleeding-edge Linux distro in terms of features and technology, but it doesn’t offer the stability or the length and quality of commercial support that RHEL is renowned for.In development since 2010, Red Hat Enterprise Linux 7 (RHEL 7) made its official debut in June 2014, and the major update offers scalability improvements for enterprises, including a new filesystem that can scale to 500 terabytes, as well as support for Docker container virtualization technology. The most recent release of RHEL, version 7.2, arrived in November 2015.
SUSE Linux Enterprise Server

SUSE Linux Enterprise Server

The Micro Focus-owned (but independently operated) SUSE Linux Enterprise Server (SLES) is stable, easy to maintain and offers 24×7 rapid-response support for those who don’t have the time or patience for lengthy troubleshooting calls. And the SUSE consulting teams will have you meeting your SLAs and making your accountants happy to boot.
SUSE Linux
Similar to how Red Hat’s RHEL is based on the open-source Fedora distribution, SLES is based on the open-source openSUSE Linux distro, with SLES focusing on stability and support over leading-edge features and technologies.The most recent major release, SUSE Linux Enterprise Server 12 (SLES 12), debuted in late October 2014 and introduced new features like framework for Docker, full system rollback, live kernel patching enablement and software modules for “increasing data center uptime, improving operational efficiency and accelerating the adoption of open source innovation,” according to SUSE.SLES 12 SP1 (Service Pack 1) followed the initial SLES 12 release in December 2015, and added support for Docker, Network Teaming, Shibboleth and JeOS images.
CentOS

CentOS

If you operate a website through a web hosting company, there’s a very good chance your web server is powered by CentOS Linux. This low-cost clone of Red Hat Enterprise Linux isn’t strictly commercial, but since it’s based on RHEL, you can leverage commercial support for it.Short for Community Enterprise Operating System, CentOS
CentOS has largely operated as a community-driven project that used the RHEL code, removed all Red Hat’s trademarks, and made the Linux server OS available for free use and distribution.In 2014 the focus shifted following Red Hat and CentOS announcing they would collaborate going forward and that CentOS would serve to address the gap between the community-innovation-focused Fedora platform and the enterprise-grade, commercially-deployed Red Hat Enterprise Linux platform.CentOS will continue to deliver a community-oriented operating system with a mission of helping users develop and adopt open source technologies on a Linux server distribution that is more consistent and conservative than Fedora’s more innovative role.At the same time, CentOS will remain free, with support provided by the community-led CentOS project rather than through Red Hat. CentOS released CentOS 7.2 in December 2015, which is derived from Red Hat Enterprise Linux 7.2.
Debian

Debian

If you’re confused by Debian’s inclusion here, don’t be. Debian doesn’t have formal commercial support but you can connect with Debian-savvy consultants around the world via theirConsultants page. Debian originated in 1993 and has spawned more child distributions than any other parent Linux distribution, including Ubuntu, Linux Mint and Vyatta.
Debian
Debian remains a popular option for those who value stability over the latest features. The latest major stable version of Debian, Debian 8 “jessie,” was released in April 2015, and it will be supported for five years.Debian 8 marks the switch to the systemd init system over the old SysVinit init system, and includes the latest releses of the Linux Kernel, Apache, LibreOffice, Perl, Python, Xen Hypervisor, GNU Compiler Collection and the GNOME and Xfce desktop environments.The latest update for Debian 8, version 8.4, debuted on April 2nd, 2016.
Oracle Linux

Oracle Linux

If you didn’t know that Oracle produces its own Linux distribution, you’re not alone. Oracle Linux (formerly Oracle Enterprise Linux) is Red Hat Enterprise Linux fortified with Oracle’s own special Kool-Aid as well as various Oracle logos and art added in.Oracle’s Linux competes directly with Red Hat’s Linux server distributions, and does so quite effectively since purchased support through Oracle is half the price of Red Hat’s equivalent model.
 Oracle Linux Server
Optimized for Oracle’s database services, Oracle Linux is a heavy contender in the enterprise Linux market. If you run Oracle databases and want to run them on Linux, you know the drill: Call Oracle.The latest release of Oracle Linux, version 7.2, arrived in November 2015 and is based on RHEL 7.2.
Mageia / Mandriva

Mageia / Mandriva

Mageia is an open-source-based fork of Mandriva Linux that made its debut in 2011. The most recent release, Mageia 5, became available in June 2015, and Mageia 6 is expected to debut in late June 2016.
Mageia and Mandriva Linux
For U.S.-based executive or technical folks, Mageia and its predecessor Mandriva might be a bit foreign. The incredibly well-constructed Mandriva Linux distribution hails from France and enjoys extreme acceptance in Europe and South America. The Mandriva name and its construction derive from the Mandrake Linux and Connectiva Linux distributions.Mageia maintains the strengths of Mandriva while continuing its development with new features and capabilities, as well as support from the community organization Mageia.Org. Mageia updates are typically released on a 9-month release cycle, with each release supported for two cycles (18 months).As for Mandriva Linux, the Mandriva SA company continues its business Linux server projects, which are now based on Mageia code.
