Definition
Red Hat is an enterprise software company, now owned by IBM, that builds its business on packaging, supporting, and selling subscriptions for open-source software, most notably its Red Hat Enterprise Linux operating system and OpenShift container platform. Rather than selling proprietary software licenses, Red Hat's model provides paid support, certification, and long-term maintenance around freely available open-source projects, letting enterprises run open-source technology in production with the reliability guarantees typically associated with commercial software.
Overview
Red Hat's business model addresses a specific tension in enterprise technology adoption: open-source software is freely available and often technically excellent, but enterprises running critical infrastructure need guarantees around security patching, long-term support, and someone accountable when something breaks, guarantees that a community-maintained open-source project alone doesn't provide. Red Hat built a company around resolving that tension, taking open-source projects like the Linux kernel and packaging them into hardened, tested, long-term-supported distributions that enterprises pay a subscription to run, with the underlying source code still freely available. Mechanically, Red Hat Enterprise Linux, the company's flagship product, takes the open-source Linux kernel and surrounding software ecosystem and applies rigorous testing, security certification, and a long support lifecycle, often a decade or more, that gives enterprises confidence to run it under regulatory and mission-critical workloads. Red Hat's subscription model doesn't sell the software itself, since it remains open source, but sells access to Red Hat's patches, updates, technical support, and certification with third-party hardware and software, which is what enterprises are actually paying for. OpenShift, Red Hat's container platform, extends this same model to Kubernetes, the open-source container orchestration system, packaging it with additional enterprise features, security hardening, and support into a product enterprises can run confidently at scale. Ansible, another major Red Hat product, provides open-source automation tooling for configuring and managing infrastructure at scale, again supported commercially by Red Hat around a freely available open-source core. Within enterprise Linux and open-source infrastructure, Red Hat's main competitors include SUSE, another commercial Linux distribution vendor, and increasingly the free community distributions that have emerged as alternatives following changes to Red Hat Enterprise Linux's source code distribution policy. Red Hat's distinguishing position remains its scale of enterprise support relationships, certification with major hardware and software vendors, and its ownership by IBM, which has increasingly positioned Red Hat's technology as the foundation of IBM's own hybrid cloud strategy. In practice, large enterprises run Red Hat Enterprise Linux as the default operating system for mission-critical servers where long-term support and vendor accountability matter, and organizations use OpenShift to run containerized applications across on-premises data centers and multiple public clouds with a consistent management layer. Government agencies and regulated industries often specifically require Red Hat's certifications and support commitments as part of their procurement and compliance requirements. The trade-offs include subscription cost compared to running the underlying open-source software directly without paid support, an option some organizations with sufficient in-house expertise choose instead, and community friction that followed Red Hat's 2023 decision to restrict public access to Red Hat Enterprise Linux's source code, which led to the rise of alternative community distributions positioning themselves as more open successors to the original CentOS project Red Hat had previously sponsored.
