Definition
AlmaLinux is a free, community-driven, open-source Linux distribution built to be binary-compatible with Red Hat Enterprise Linux (RHEL), providing a stable enterprise-grade alternative for production servers.
Overview
AlmaLinux emerged after Red Hat changed the positioning of CentOS from a stable downstream rebuild of RHEL to a rolling-release preview branch (CentOS Stream), which left a gap for organizations that relied on CentOS's traditional role: a free, stable, long-supported RHEL clone for production servers. AlmaLinux was created to fill that gap, aiming for strict binary compatibility with RHEL so that software built or certified for RHEL runs unmodified — a very different design goal from a minimal, from-scratch distribution like Alpine Linux. Governance was structured around a nonprofit foundation to keep the project community-driven rather than tied to a single commercial sponsor's roadmap, and it follows RHEL's release cadence and long-term support lifecycle. In practice, AlmaLinux is used the same way CentOS previously was: as a dependable base OS for production servers, often deployed alongside tools like Docker for containerized workloads or provisioned via infrastructure-as-code, in environments where teams want RHEL-like stability without a RHEL subscription — much as Ubuntu is chosen for a different balance of familiarity and community support on Linux servers.
