Ten years of contract-guaranteed long-term support is also category-leading: https://access.redhat.com/support/policy/updates/errata https://access.redhat.com/support/policy/updates/errata Particularly for systems that are installed as appliances in customer data-centers, where you as the vendor are both (a) responsible for the appliance as a whole to continue working but (b) have little / restricted access to continue maintaining it, RHEL helps you sign long multi-year support contracts for said appliance with the customer while keeping your maintenance costs to a minimum (since the cost of hiring more support engineers then flying them out is going to be higher than the RHEL license cost).
