Ubuntu: The other major enterprise Linux, with paid support available and a shorter default lifecycle

Commercial Linux distribution with long-term support
Overview
Red Hat Enterprise Linux is a commercial Linux distribution built for servers and workstations where the operating system has to stay supported for a decade. Its value is not the code, which is open source, but the subscription: security backports, certified hardware and software compatibility, and a support contract someone can be held to. That is why it dominates regulated industries. When an auditor asks who is accountable for a CVE in your kernel, "Red Hat, under contract" is an answer and "the community" is not. The ten-year lifecycle also means an application certified once keeps running without a distribution upgrade project every two years.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Red Hat Enterprise Linux.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Answered, with sources
Each answer names the page it came from, so you can check it rather than take our word for it.
The software is open source but the product is sold as a per-system subscription. Red Hat offers no-cost developer subscriptions for individual development use.
Support, security backports over a ten-year lifecycle, and hardware and software certifications. Not the code, which is open.
Accountability and lifecycle. A contracted vendor answering for a CVE, and an OS that stays supported long enough to avoid re-certifying applications every two years.

Softwr does not host reviews and shows no star rating for Red Hat Enterprise Linux, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
