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:
“Every one of my friends had a bad day somewhere in her history she wished she could forget but couldnt. A very bad mother day changes you forever. Those were the hardest stories to tell. . . . I could still see the red imprint of his little bum when I changed his diaper that night. I stared at my hand, as if they were alien parts of myself . . . as if they had betrayed me. From that day on, I never hit him again.”
—Mary Kay Blakely (20th century)
“As a cure for the cold, take your toddy to bed, put one bowler hat at the foot, and drink until you see two.”
—Robert Bruce, Sir Lockhart (18861970)
“Every diminution of the public burdens arising from taxation gives to individual enterprise increased power and furnishes to all the members of our happy confederacy new motives for patriotic affection and support.”
—Andrew Jackson (17671845)
