Linux Server OS

A Linux server is a high-powered variant of the Linux open source operating system that's designed to handle the more demanding needs of business applications such as network and system administration, database management and Web services.

Linux servers are frequently selected over other server operating systems for their stability, security and flexibility advantages. Leading Linux server operating systems include CentOS, Debian, Ubuntu Server, Slackware and Gentoo.

Listed here are the top ten Linux server — some of which you may not be aware

1. 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 leaves the others fumbling in the dusty distance.

2. Red Hat

Red Hat Enterprise Linux (RHEL) started out as the "little Linux company that could" and 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 will have you coming back for more.

3. SUSE

Novell-owned SUSE Linux is stable, easy-to-maintain and offers Novell's 24x7 rapid-response support for those who don't have the time or patience for lengthy troubleshooting calls. And, Novell's consulting teams will have you meeting your SLAs and making your accountants happy to boot.

4. Mandriva

For U.S.-based executive or technical folks, Mandriva might be a bit foreign. This incredibly well-constructed Linux distribution hails from France and enjoys extreme acceptance in Europe and South America. It is, as its website claims, a worldwide Linux provider. Its name and its construction derive from the Mandrake Linux and Connectiva Linux distributions.

5. Xandros

If you prefer a Linux server distro with a Microsoft connection, Xandros is the one for you. Rumors aside, Xandros and Microsoft collaborate in what's known in technical circles as "cooperatition." This means that they compete cooperatively. To find out more about this unique perspective, check out the Xandros About page.

6. Slackware

While not generally associated with commercial distributions, Slackware maintains relationships with several companies that provide fee-based support. One of the earliest available Linux server distributions, Slackware has an extensive and faithful fan base. Its developers regularly release new versions.

7. 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 their Consultants page. Debian has spawned more child distributions than any other parent Linux distribution, including Ubuntu, Linux Mint and Vyatta.

8. Vyatta

Vyatta is more at home on routers and firewalls than PC-based systems, but if you want a commercially-driven distribution for those applications, Vyatta works well for your secure communications needs. Check out the free version of Vyatta Linux.

9. CentOS

It's true that CentOS isn't strictly commercial but since it's based on Red Hat Enterprise Linux (RHEL), you can leverage commercial support for it. CentOS has its own repositories and community support and is not the same as Fedora Linux.

10. Unbreakable Linux

Oracle's Unbreakable Linux is Red Hat Enterprise Linux with some Oracle logos and art added in. Oracle's Unbreakable 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.
