Among the biggest changes in the new Red Hat release is the fact that Red Hat is now doubling the support length from the 1.5 years that was available in OSP 4.0 to three years with OSP 5.0.
A key value proposition that Red Hat offers with OSP is commercial support and enterprise hardening. Since OpenStack is an open-source effort, there are a number of freely available OpenStack distributions, including Red Hat’s own community RDO distribution. The free OpenStack distributions, however, generally do not have any form of commercial support.
