CloudLinux OS is an operating system designed specifically for shared hosting providers, developed by computer software company CloudLinux Inc. CloudLinux OS is based on OpenVZ kernel and is fully compatible with CentOS/RHEL packages. CloudLinux OS is designed to improve stability and security on server and to optimize its work on account of isolating tenants on server, setting resource usage limits for them, optimizing work with databases etc.
openSUSE is a freely available, community project that releases versions on a comparatively frequent basis and generally uses the latest versions of the various open source projects that it includes. SUSE Linux Enterprise is SUSE’s commercial edition, which SUSE releases much less frequently, enabling it to offer support more effectively for enterprise/production deployments. It is certified for a wide variety of enterprise applications and offers a number of special enterprise features including High Availability and Point of Sale extensions. SUSE historically uses a heavily tested subset of packages from openSUSE Linux as the basis for SUSE Linux Enterprise.
SL is a Linux release put together by Fermilab, CERN, and various other labs and universities around the world. Its primary purpose is to reduce duplicated effort of the labs, and to have a common install base for the various experimenters.
The base SL distribution is basically Enterprise Linux, recompiled from source.
Our main goal for the base distribution is to have everything compatible with Enterprise, with only a few minor additions or changes. Examples of items that were added are Alpine, and OpenAFS.
The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system that we have created is called Debian. An operating system is the set of basic programs and utilities that make your computer run. At the core of an operating system is the kernel. The kernel is the most fundamental program on the computer and does all the basic housekeeping and lets you start other programs.
Debian systems currently use the Linux kernel or the FreeBSD kernel. Linux is a piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. FreeBSD is an operating system including a kernel and other software. However, work is in progress to provide Debian for other kernels, primarily for the Hurd. The Hurd is a collection of servers that run on top of a microkernel (such as Mach) to implement different features. The Hurd is free software produced by the GNU project. A large part of the basic tools that fill out the operating system come from the GNU project; hence the names: GNU/Linux, GNU/kFreeBSD, and GNU/Hurd. These tools are also free.
Fedora Server is a short-lifecycle, community-supported server operating system that enables seasoned system administrators experienced with any OS to make use of the very latest server-based technologies available in the open source community.
The CentOS Linux distribution is a stable, predictable, manageable and reproducible platform derived from the sources of Red Hat Enterprise Linux (RHEL). They are now looking to expand on that by creating the resources needed by other communities to come together and be able to build on the CentOS Linux platform.
