What is AlmaLinux? :

AlmaLinux is a new Linux distro, initially forked from the Red Hat Enterprise Linux (RHEL) 8. Due to the discontinuation of CentOS Linux, the most widely used free and open source, server grade operating system. The community is desperately looking for CentOS 8 alternatives. The CloudLinux is the first company that took the initiative to provide the AlmaLinux (Forever-Free-Enterprise-Grade Operating System) that was 1:1 binary compatible fork of RHEL 8.

As a standalone, completely free OS, AlmaLinux enjoys $1M in annual sponsorship from CloudLinux Inc. Launched with the code-name Project Lenix, AlmaLinux is an open-source, community-driven project that intends to fill the gap left by the demise of the CentOS Linux operating system.
