| Description of Support for Red Hat Enterprise Linux:
Red Hat Enterprise Linux products are delivered through an annual subscription with one year of support services and access to Red Hat Enterprise Network. The enterprise products strive to be stable, with a 12-18 month release cycle and five years of support for every version, in contrast with their ‘public’ releases (Red Hat Linux) which occur every 4 – 6 months.
The support services consist of what Red Hat calls errata updates. These updates contain security, bug fix and enhancement errata that have been qualified on the appropriate Red Hat Enterprise Linux release and architecture. The scope of enhancement errata is constrained to additional hardware support. Security errata are released independent of the updates.
Red Hat levels of support are:
-
Basic Edition, which provides 90-days of Installation and Configuration support (Monday-Friday 9am-5pm ET);
-
Standard Edition, which provides 24x7 Web/Email based support (2 day response time), and Business Hours Phone based support;
-
Premium Edition, which provides 24x7 Web/Email based support (1 day response time), Business Hours Phone based support, and 24x7 Severity One Emergency phone support.
