Famous scientific research institutes Fermilab and CERNissued a joint statement, announced that it will adopt AlmaLinux in its research facilities. The statement reads that the advantages of AlmaLinux include the long support life of each major version, support for extended architecture, fast release cycle, contributions from the upstream community, support for security advisory metadata, and perfect compatibility with Red Hat Enterprise Linux and other refactored versions.

AlmaLinux is an open source, community-driven project compiled from the source code of Red Hat Enterprise Linux (RHEL). AlmaLinux is fully binary compatible with RHEL 8 from the creators of the CloudLinux OS. The AlmaLinux team promises to provide the AlmaLinux operating system for free forever, and the project will be permanently open source without any restrictions and fees, and will be supported until 2029.

In 2020, Red Hat decided to stop using CentOS Linux as an independent distribution, and instead launched a rolling update distribution, CentOS Stream, as an upstream beta version of the enterprise distribution RHEL. The community immediately launched several projects to replace CentOS, the most prominent of which were two projects: Rocky Linux, sponsored by the Rocky Enterprise Software Foundation; and AlmaLinux, sponsored by the AlmaLinux OS Foundation.
