Red Hat Enterprise Linux (RHEL)

Why do you need Red Hat Enterprise Linux?

The operating system is the part of the IT infrastructure whose cost is not the licence but the decade that follows it: who ships the security patch, how long, and what happens when the application vendor stops certifying the version you are on. That is the actual comparison worth making here.

Linux in enterprise requires stability and professional support. Community distributions don’t offer SLAs. Security patches without testing can cause problems. Hardware compatibility uncertain. Compliance requires documentation and auditability.

Red Hat Enterprise Linux is built for long-lived production workloads. A ten-year lifecycle means the platform outlives the project that deployed it. Certified hardware means the vendor support conversation has one party, not three. Live kernel patching means a security update need not become a maintenance window.
