Red Hat Linux is also known for its package management system, which allows users to easily install, update, and remove software packages from their system. The distribution includes a wide range of open-source software packages, including tools for system administration, development, networking, and security.
In recent years, Red Hat Linux has evolved into the Red Hat Enterprise Linux (RHEL) distribution, which is geared towards enterprise customers and provides a long-term support cycle. Red Hat also offers a variety of other products and services, including containerization technologies, cloud computing solutions, and consulting services.
Red Hat Enterprise Linux, or RHEL, is a commercial open-source distribution of Linux integrated by Red Hat for the wholesale market. It is published in server editions for x86-64 Power ISA, IBM Z, ARM64 and a desktop edition for x86-64. All the official training and support of Red Hat, with the Red Hat Certification Program, concentrates on the Red Hat Enterprise Linux environment.
Red Hat Linux has gone through many changes over the years. It was originally released in 1994, and the latest major release of Red Hat Enterprise Linux (RHEL) is version 9, which was released in April 2021. Here are some of the major variants of Red Hat Linux:
Red Hat Enterprise Linux (RHEL) - This is the flagship distribution of Red Hat, designed for enterprise use. It is a commercial distribution with paid support and long-term support (LTS) options.
CentOS - CentOS is a community-supported version of RHEL that is free to download and use. It is essentially RHEL without the Red Hat branding and paid support options.
Fedora - Fedora is a community-supported distribution that serves as a testing ground for new features that will eventually make their way into RHEL. It is a cutting-edge distribution that is updated frequently.
Red Hat Linux Advanced Server - This was an earlier version of Red Hat Linux that was designed for enterprise use. It has since been replaced by RHEL.
Red Hat Linux 9 - This was the final release of the original Red Hat Linux distribution before it was replaced by Fedora and RHEL.
Red Hat Linux for PowerPC - This was a version of Red Hat Linux that was designed to run on PowerPC-based Macintosh computers.
