Which is the better OS? CentOS vs RHEL (Red Hat Enterprise Linux)

Since CentOS and Red Hat Enterprise Linux are binary-compatible, the key differences come down to costs and support. With CentOS losing support soon, the choice becomes clear.

What is the crucial difference that sets RHEL and CentOS apart?

When comparing CentOS and Red Hat Enterprise Linux (RHEL), the first thing that connects the Linux distributions is their shared foundation. RHEL, developed by Red Hat in Raleigh, North Carolina, is clearly reflected in its name. Red Hat also plays a significant role in CentOS. Since its launch in 2002, RHEL has become one of the most popular and reliable Linux platforms for commercial use, offering high stability, strong security architecture, and broad compatibility with various software packages. However, using RHEL requires a paid support contract.

To provide a cost-effective alternative, CentOS was introduced in 2004. This Linux distribution is built on the source packages of Red Hat Enterprise Linux and offers a binary-compatible alternative. This ‘Community Enterprise Operating System’ is maintained by the CentOS project and is open source, making it much cheaper to use than the commercial source. CentOS supports nearly all software compatible with RHEL. Initially met with skepticism by Red Hat, the two officially merged in 2014, establishing CentOS as the community version of Red Hat Enterprise Linux.

We took a look at both systems for you and explain here who has the edge in the duel between CentOS and Red Hat Enterprise Linux.

Intended use and target group

Red Hat Enterprise Linux (RHEL) leads the commercial Linux distribution market, specifically tailored for enterprise use, with a focus on security, stability, and flexibility. In contrast, private users often opt for more affordable or free alternatives like CentOS. Primarily designed for private use, CentOS provides many features and benefits without the high costs, making it a viable option for smaller companies, offering access to most RHEL packages.

Different system solutions

Compared to CentOS, RHEL offers significantly more options. Red Hat delivers a comprehensive package of system, software, add-ons, and tailored support for virtually any purpose, making it suitable for desktop use, servers, and cloud solutions. In contrast, CentOS is more of a one-size-fits-all solution, lacking the specialisation of RHEL. As a result, users must assemble the necessary software for specific needs on their own.

Support options

As a community project, CentOS benefits from a large and active user base, offering a wealth of advice and support from fellow users. The CentOS community is extensive and known for its helpfulness, but there is no official support from the CentOS project or Red Hat. While third-party companies provide paid support, it lacks direct commercial backing. In contrast, RHEL includes access to individual support as part of its payment model, providing tailored assistance for any issues. Additionally, RHEL provides three distinct support tiers for each version.

The ‘Full Support’ model is valid for five years from the initial release. During this time, registered users receive updates and security patches. This is followed by ‘Maintenance Support’, which is valid for the next five years. This is followed by the ‘Extended Life Phase’ option, which is available for up to two more years. Bug fixes can also be ordered as an option. As CentOS will be discontinued, there will be no more updates and security patches from summer 2024.

Which solution is better? CentOS vs Red Hat Enterprise Linux

The comparison between CentOS and RHEL is clear for the future. With CentOS ending support, it can no longer be operated securely, making it crucial for companies to find an alternative to CentOS. Red Hat Enterprise Linux remains a top choice. Both operating systems offer similar features and align in many aspects. Although RHEL requires a subscription, it provides superior support, making the investment worthwhile for businesses.
