Red Hat Enterprise Linux is a Linux distribution developed by Red Hat for the commercial market.
Red Hat Enterprise Linux is released in server versions for x86-64, Power ISA, ARM64, and IBM Z, and a desktop version for x86-64.
Originally, Red Hat's enterprise product, then known as Red Hat Linux, was made freely available to anybody who wished to download it, while Red Hat made money from support.
Red Hat then moved towards splitting its product line into Red Hat Enterprise Linux which was designed to be stable and with long-term support for enterprise users and Fedora as the community distribution and project sponsored by Red Hat.
All of Red Hat's official support and training, together with the Red Hat Certification Program, focuses on the Red Hat Enterprise Linux platform.
Red Hat Enterprise Linux is often abbreviated to RHEL.
This free developer subscription was announced on March 31, 2016.
There are also "Academic" editions of the Desktop and Server variants.
Rebuilds of Red Hat Enterprise Linux are free but do not get any commercial support or consulting services from Red Hat and lack any software, hardware or security certifications.
Red Hat uses strict trademark rules to restrict free re-distribution of their officially supported versions of Red Hat Enterprise Linux, but still freely provides its source code.
Third-party derivatives can be built and redistributed by stripping away non-free components like Red Hat's trademarks.
Examples include community-supported distributions like Cent OS and Scientific Linux, and commercial forks like Oracle Linux.
Developers need to register for the Red Hat Developer Program and agree to licensing terms forbidding production use.Fedora is a general purpose system that gives Red Hat and the rest of its contributor community the chance to innovate rapidly with new technologies.
