AlmaLinux is a community-driven, open-source Linux distribution that serves as a drop-in replacement for CentOS. It focuses on stability, security, and long-term support, making it suitable for enterprise environments and production systems. AlmaLinux OS is binary-compatible with RHEL, and is owned and controlled by the non-profit AlmaLinux OS Foundation, managed by a community-elected board of directors. Major releases are typically available within a few days to a few weeks following a major RHEL release.
