Open source allows user to modify the software and make it redistributable as and when required. The open source license requires improved versions of the software to carry a different name or version from the original software. Red Hat Enterprise Linux, and Fedora both are open source products. If a product or a software is upstream that means it allows the origin author/s to maintain it or perform any bug fixes. Fedora is an upstream of Red Hat Enterprise Linux.

== Fedora
|
|

Fedora is based on Linux kernel and GNU programs. Fedora is developed and sponsored by Fedora Project and Red Hat. Fedora is a general purpose system that gives Red Hat and the rest of its contributor community the chance to innovate rapidly with new technologies. In order to focus Red Hat's efforts and limit support costs, only a selected subset of packages found in Fedora are included in the commercially supported product line. The Fedora Project has a community of people maintaining add-on packages for Red Hat Enterprise Linux and compatible rebuilds called https://fedoraproject.org/wiki/About_EPEL[Extra Packages for Enterprise Linux], or EPEL.
