The RHEL 9 Beta was used as the basis for the RHEL 9 GA release. It I featured a handful of proprietary features for licensed users. The RHEL 9 Beta was released to the public on November 3, 2021, one month ahead of CentOS Stream 9. As we note later, there will be (and are) open source equivalents to a CentOS Linux 9 release this year, including AlmaLinux 9, Rocky Linux 9, and others. RHEL 9 marked the first version of RHEL based on the upstream CentOS Stream version. This Fedora to RHEL to CentOS fork process continued all the way up through CentOS 8, at which time the Red Hat and CentOS communities announced the end of CentOS Linux in favor of their recently created upstream rolling release distribution CentOS Stream. In comparison to Fedora releases, RHEL releases came at a much slower pace - one more digestible to enterprises averse to frequent OS upgrades. RHEL, starting with RHEL 4, has been derived from upstream Fedora Linux releases, with Fedora providing the fast innovation necessary to stay competitive in a crowded commercial server operating system market. The "first" RHEL release, RHEL 2.1 was forked to form the first CentOS Linux release, CentOS Linux 2. Originally released as "Red Hat Linux Advanced Server," RHEL has since released eight major versions ranging from RHEL 2.1 to the recent RHEL 9. How Will These Changes Impact RHEL-Derived Distributions?īack to top RHEL 9 Overview: How We Got Here.Its completely trouble free operating system and don't have an issue with viruses, malware and slowing down your computer.Above all you don't have to pay for software and server licensing to install Linux, its absolutely free and you can install it on as many computers as you want.Companies like Google, Amazon and Facebook use linux in order to protect their servers as it is highly reliable and stable.
