Centos, which stands for C ommunity En terprise O perating S ystem, is the result of a group of open source contributors and users working together to develop Linux solutions that are freely available to users who do not require a great deal of commercial support to achieve their goals. Centos dedicated servers were designed based on Red Hat's product, Red Hat Enterprise Linux. Although the Red Hat Linux server is made entirely of free and open source software, it is only distributed to the public in binary form (including CD-ROM and DVD-ROM) at a fee paid by subscribers.
However, Red Hat does release its source code for its product under the terms of the GNU General Public License, so the use of the code for the creation of the Centos Linux distribution is an entirely valid and acceptable practice. The distribution of Centos products completely complies with Red Hat's redistribution policy. The Centos server is almost identical to the Red Hat product except that it is modified to remove all Red Hat branding and artwork. Centos and its Linux solutions are not in any way affiliated with or supported by Red Hat, Inc.
