What is CentOS?
CentOS (Community Enterprise Operating System) is an open source enterprise Linux distribution. It is a free and community-supported operating system based on the source code of Red Hat Enterprise Linux (RHEL). CentOS aims to provide a stable, reliable, and secure platform for individuals and organizations seeking to deploy and manage Linux-based infrastructures.
History and Development
CentOS was initially released in 2004 as a downstream clone of RHEL. It was created following a split in the open source community, where the original development team of an earlier project called “CentOS Linux” merged with a group called “White Box Enterprise Linux” to form CentOS.
The goal of CentOS is to create an operating system that is virtually identical to RHEL, both in terms of binary compatibility and overall user experience. CentOS achieves this by utilizing the same source code as RHEL, with the necessary branding and artwork changes.
