Red Hat Enterprise Linux (RHEL) is a Linux distribution produced by Red Hat and targeted toward the commercial market, including mainframes. 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.
Verbatim copying and redistribution of the entire Red Hat Enterprise Linux distribution is not permitted due to trademark restrictions. However, there are several redistributions of Red Hat Enterprise Linux—such as CentOS—with trademarked features (such as logos, and the Red Hat name) removed.
There are also "Academic" editions of the Desktop and Server variants. They are offered to schools and students, are less expensive, and are provided with Red Hat technical support as an optional extra. Web support based on number of customer contacts can be purchased separately.
It is often assumed the branding ES and AS stand for "Entry-level Server" and "Advanced Server", respectively. The reason for this is that the ES product is indeed the company's base enterprise server product, while AS is the more advanced product. However, nowhere on its site or in its literature does Red Hat say what AS, ES and WS stand for.
In Red Hat Enterprise Linux 5 there are new editions that substitute former Red Hat Enterprise Linux AS/ES/WS/Desktop:
* Red Hat Enterprise Linux Advanced Platform (former AS)
* Red Hat Enterprise Linux (former ES) (limited to 2 CPU-s)
* Red Hat Enterprise Linux Desktop with Workstation and Multi-OS option
* Red Hat Enterprise Linux Desktop with Workstation option (former WS)
* Red Hat Enterprise Linux Desktop with Multi-OS option
* Red Hat Enterprise Linux Desktop (former Desktop)
Red Hat had also announced its Red Hat Global Desktop Linux edition "for emerging markets". But as per a recent press release it has totally dropped the idea of its Global Desktop. "There won't be a consumer desktop from Red Hat as it's not going to be profitable".
RHEL 3 and 4 and previous releases had four variants:
* Red Hat Enterprise Linux AS for mission-critical/enterprise computer systems.
* Red Hat Enterprise Linux ES for supported network servers
* Red Hat Enterprise Linux WS for technical power-user enterprise desktops for high-performance computing
* Red Hat Desktop for multiple deployments of single-user desktops for enterprises.
