Red Hat Enterprise Linux (RHEL) is an enterprise operating system based on Linux and developed by the American multinational company Red Hat, Inc. with corporate headquarters in North Carolina. The first version of RHEL dates from the year 2000 and its development has remained constant to date. Each of the versions has support for 10 years from the date of its release. Because it is a commercial version, it enjoys added values such as training, consulting, certification, among others. The Red Hat Enterprise Linux Server Edition has a current cost of $ 349.
Community Enterprise Operating System (CentOS) is an operating system based on the source code of RHEL, which has been removed all logos and trademarks owned by Red Hat, Inc. for free distribution. The software operates in a similar way to RHEL, being reliable, robust, easy to install and use. Its first version was launched in 2004 and from 2007 it has security updates guaranteed for 10 years. CentOS is one of the most used operating systems in the Data Processing Centers.
