CentOS

CentOS

CentOS (Community ENTerprise Operating System) is a Linux distribution based on and binary-compatible with the Red Hat Enterprise Linux (RHEL) distribution from Red Hat. The distribution is managed, maintained and developed by an open group of voluntary developers.

CentOS is one of the most popular Linux distributions for web servers.
The purpose of CentOS is to provide a fully RHEL binary-compatible Linux distribution. In addition, there is a fast response time in terms of providing updates and the possibility to purchase additional support for CentOS.
Red Hat provides all source packages for the RHEL distribution on the net, enabling the development of a binary-compatible Linux distribution to RHEL. RHEL can only be purchased in conjunction with support contracts, but through compatible alternatives such as CentOS, it is possible to install more computers with RHEL-compatible Linux distributions than RHEL licenses have been purchased.

In addition to the savings, there is the advantage that commercial Linux software certified for RHEL can also be used directly and without restrictions on the alternative distribution.
