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:
“Now wait a minute. You listen to me. I’m an advertising man, not a red herring. I’ve got a job, a secretary, a mother, two ex- wives, and several bartenders dependent on me. And I don’t intend to disappoint them all by getting myself slightly killed.”
—Ernest Lehman (b.1920)
“The hat is not for the street: it will never be democratized. But there are certain houses that one cannot enter without a hat. And one must always wear a hat when lunching with people whom one does not know well. One appears to one’s best advantage.”
—Coco Chanel (1883–1971)
“Socialism proposes no adequate substitute for the motive of enlightened selfishness that to-day is at the basis of all human labor and effort, enterprise and new activity.”
—William Howard Taft (1857–1930)
