Red Hat Linux
Red Hat Enterprise Linux, or RHEL, is a commercial open-source distribution of Linux integrated by Red Hat for the wholesale market. It is published in server editions for x86-64 Power ISA, IBM Z, ARM64 and a desktop edition for x86-64. All the official training and support of Red Hat, with the Red Hat Certification Program, concentrates on the Red Hat Enterprise Linux environment.
The initial edition of RHEL came on the market as "Red Hat Linux Advanced Server", for bearing the name originally. Red Hat renamed Red Hat Linux Advanced Server to the "Red Hat Enterprise Linux AS" name and included two more versions, Red Hat Enterprise Linux WS and Red Hat Enterprise Linux ES, in 2003.
Red Hat utilizes strict trademark rules to limit free re-distribution of the officially supported editions of Red Hat Enterprise Linux but freely offers its source code. All third-party derivatives can be re-distributed and built by stripping away paid components like the trademarks of Red Hat. Examples contain community-supported distributions such as AlmaLinux and Rocky Linux and commercially forked such as Oracle Linux.
Variants of Red Hat Linux
The server subscription of Red Hat Enterprise Linux is freely available for development purposes. Developers are only required to register for the developer program of Red Hat and acknowledge license terms for production use. The free developer subscription was revealed on 31 March 2016.
Also, there are "Academic" editions of the server and desktop variants. They are provided to students and schools, are inexpensive, and are offered with the technical support of Red Hat as an extra option. Web support based on the total of customer contacts can separately be purchased.
Often, it is assumed the branding WS, AS, and ES stand for "Work Station", "Advanced Server", and "Entry-level Server", respectively. The reason for it is that the Entry-level Server product is indeed the base enterprise server product of the company, while Advanced Server is the more advanced product.
There are new versions that replace the former RHEL Desktop/WS/ES/AS in Red Hat Enterprise Linux:
Also, Red Hat had revealed its Red Hat Global Desktop Linux version "for emerging markets".
