Red Hat Enterprise Linux is one of a number of variants (also referred to as distributions) of the Linux operating system and is the product of a U.S. company named Red Hat, Inc., based in Raleigh, North Carolina. The company was founded in the mid-1990s through the merger of two companies owned at the time by Marc Ewing and Bob Young. The origins of Linux, however, go back even further. This chapter will outline the history of both the Linux operating system and Red Hat, Inc.
What exactly is Linux?
Linux is an operating system in much the same way that Windows is an operating system (and there any similarities between Linux and Windows end). The term operating system is used to describe the software that acts as a layer between the hardware in a computer and the applications that we all run on a daily basis. When programmers write applications, they interface with the operating system to perform such tasks as writing files to the hard disk drive and displaying information on the screen. Without an operating system, every programmer would have to write code to directly access the hardware of the system. In addition, the programmer would have to be able to support every single piece of hardware ever created to be sure the application would work on every possible hardware configuration. Because the operating system handles all of this hardware complexity, application development becomes a much easier task. Linux is just one of a number of different operating systems available today.
Who Created Linux?
The origins of Linux can be traced back to the work and philosophies of two people. At the heart of the Linux operating system is something called the kernel. This is the core set of features necessary for the operating system to function. The kernel manages the system’s resources and handles communication between the hardware and the applications. The Linux kernel was developed by Linus Torvalds who needed an operating system but didn’t want to have to buy one. When he had finished the first version of the kernel he released it under an open source license that enabled anyone to download the source code and freely use and modify it without having to pay Linus any money.
Around the same time GNU/Linux (in fact, at one time, Richard Stallman refused to give press interviews to any publication which failed to refer to Linux as GNU/Linux). This is not unreasonable given that the GNU tools developed by the Free Software Foundation make up a significant and vital part of GNU/Linux. Unfortunately, most people and publications simply refer to Linux as Linux and this will probably always continue to be the case.
The Early Days of Red Hat
In 1993 Bob Young created a company named ACC Corporation which, according to Young, he ran from his “wife’s sewing closet”. The name ACC was intended to represent a catalog business but was also an abbreviation of a small business his wife ran called “Antiques and Collectibles of Connecticut”. Among the items sold through the ACC catalog business were Linux CDs and related open source software.

In 1995, ACC acquired Red Hat, adopted the name Red Hat, Inc. and experienced rapid and significant growth. Bob Young stepped down as CEO shortly after the company went public in August of 1999 and has since pursued a number of business and philanthropic efforts including a print-on-demand book publishing company named Lulu and ownership of two Canadian professional sports teams. In 2018, IBM announced plans to acquire Red Hat, Inc. in a deal valued at $34 billion.
Red Hat Support
Early releases of Red Hat Linux were shipped to customers on floppy disks and CDs (this, of course, predated the widespread availability of broadband internet connections). When users encountered problems with the software they were only able to contact Red Hat by email. In fact, Bob Young often jokes that this was effective in limiting support requests since, by the time a customer realized they needed help, their computer was usually inoperative and therefore unavailable to be used to send an email message seeking assistance from Red Hat’s support team. In later years Red Hat provided better levels of support tied to paid subscriptions and now provides a variety of support levels ranging from “self help” (no support) up to premium support.
Open Source
Red Hat Enterprise Linux 8 is the latest commercial offering from Red Hat and is primarily targeted at corporate, mission critical installations. It is also the cornerstone of an expanding ecosystem of products and services offered by Red Hat. RHEL is an open source product in that you can download the source code free of charge and build the software yourself if you wish to do so (a task not to be undertaken lightly). If, however, you wish to download a pre-built, ready to install binary version of the software (either with or without support), you have to pay for it.
The Fedora Project
Red Hat also sponsors the Fedora Linux also serves as a proving ground for many of the new features that are eventually adopted into the Red Hat Enterprise Linux operating system family. RHEL 8.0, for example, was based to a large extent on Fedora 29.
CentOS - The Free Alternative
For users unable to afford a Red Hat Enterprise Linux subscription, another option is provided in the form of the CentOS operating system. The CentOS project, originally a community driven effort but now a collaboration with Red Hat, takes the Red Hat Enterprise Linux source code, removes the Red Hat branding and subscription requirements, compiles it and provides the distribution for download. Of course, while CentOS provides an operating system that is identical to RHEL in many ways, it does not include access to Red Hat technical support.
Summary
The origins of the Linux operating system can be traced back to the work of Linus Torvalds and Richard Stallman in the form of the Linux kernel combined with the tools and compilers built by the GNU project.
Over the years, the open source nature of Linux has resulted in the release of a wide range of different Linux distributions. One such distribution is Red Hat Enterprise Linux, created by Red Hat, Inc., a company founded by Bob Young and Mark Ewing. Red Hat specializes in providing enterprise level Linux software solutions combined with extensive technical support services.
