Updating redhat 8
Red Hat Enterprise Linux release schedules do not follow that of Fedora (around 6 months per release) but are more conservative (2 years or more).
Fedora serves as upstream for future versions of RHEL.
However, nowhere on its site or in its literature does Red Hat say what AS, ES and WS stand for.
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.
RHEL trees are forked off the Fedora repository, and released after a substantial stabilization and quality assurance effort.
For example, RHEL 6 was forked from Fedora at the end of 2009 (approximately at the time of the Fedora 12 release) and released more or less together with Fedora 14.
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.
