Red Hat Enterprise Linux (RHEL) is a Linux-based operating system developed by Red Hat and targeted toward the commercial market. Red Hat Enterprise Linux is released in server versions for x86, x86-64, Itanium, PowerPC and IBM System z, and desktop versions for x86 and x86-64. All of Red Hat's official support and training and the Red Hat Certification Program center around the Red Hat Enterprise Linux platform. Red Hat Enterprise Linux is often abbreviated to RHEL, although this is not an official designation.
The first version of Red Hat Enterprise Linux to bear the name originally came onto the market as "Red Hat Linux Advanced Server". In 2003 Red Hat rebranded Red Hat Linux Advanced Server to "Red Hat Enterprise Linux AS", and added two more variants, Red Hat Enterprise Linux ES and Red Hat Enterprise Linux WS.
While Red Hat uses strict trademark rules to restrict free re-distribution of their officially supported versions of Red Hat Enterprise Linux, Red Hat freely provides the source code for the distribution's software even for software where this is not mandatory. As a result, several distributors have created re-branded and/or community-supported re-builds of Red Hat Enterprise Linux that can legally be made available, without official support from Red Hat. CentOS aims to provide 100% binary compatibility to Red hat Linux.

Famous quotes containing the words red, hat and/or enterprise:
“How red the rose that is the soldier’s wound,
The wounds of many soldiers, the wounds of all
The soldiers that have fallen, red in blood,
The soldier of time grown deathless in great size.”
—Wallace Stevens (1879–1955)
“I saw a guide-post surmounted by a pair of moose horns.... They are sometimes used for ornamental hat-trees, together with deer’s horns, in front entries; but ... I trust that I shall have a better excuse for killing a moose than that I may hang my hat on his horns.”
—Henry David Thoreau (1817–1862)
“God sent children for another purpose than merely to keep up the race—to enlarge our hears; and to make us unselfish and full of kindly sympathies and affections; to give our souls higher aims; to call out all our faculties to extended enterprise and exertion; and to bring round our firesides bright faces, happy smiles, and loving, tender hearts.”
—Mary Botham Howitt (20th century)
