Red Hat Enterprise Linux (RHEL) and CentOS are the biggest names in enterprise-grade Linux distributions. Both provide numerous capabilities, unwavering reliability, and laser-like attention to security—all essential components for creating dependable server infrastructure. 

However, since Red Hat and CentOS have a lot of features in common, choosing between them can take time and effort.

With the help of this thorough guide, which delves deeply into the nuances of both distributions, you can make an informed choice depending on your unique requirements. 

We will examine their histories, fundamental advantages, and salient distinctions to make sure you select the ideal Linux server for your undertaking.

Knowing the Red Hat Ecosystem

Renowned open-source software company Red Hat is in charge of developing RHEL. Firm stability, extensive testing, and a steady release schedule are the top priorities of this commercially supported distribution. 

Red Hat Virtualization, a virtualization solution, and Red Hat OpenShift, a platform for containerization, are only two of the numerous Red Hat products that are built on top of RHEL.

The most valuable Linux distribution is Red Hat Enterprise Linux (RHEL), an enterprise-level distribution that is supported commercially. RHEL offers a reliable and secure platform for mission-critical applications and is well-known for its long release cycles, stringent testing protocols, and rock-solid stability.

The Enterprise Linux Red Hat Power

1. Unwavering Stability

RHEL as a data center solution has a solid reputation for stability and long-term support. Updates and security fixes are applied to every major release for a minimum of 10 years, so mission-critical deployments can be completed without concern.

2. Proactive security alerts

Access to skilled support engineers, and knowledge base articles are just a few of the extensive support options that Red Hat offers for enterprise-level customers. Organizations looking for a dependable safety net for their vital infrastructure will find this premium support to be extremely helpful.

3. Certification Powerhouse

RHEL is the cornerstone of many industry certifications, especially those about Red Hat technologies. It is also known as the Certification Powerhouse. Possessing these credentials increases the competence and efficacy of your IT staff's management of Red Hat systems.

4. A Thriving Ecosystem

A wide range of third-party software solutions that are certified compatible with RHEL are available within the thriving Red Hat ecosystem. This broad compatibility makes integration easier and gives you the flexibility to use a variety of solutions to suit your needs.

 

The Bottom Line for RHEL: RHEL is the clear winner if stability, security, and extensive support are critical components of your server setup. It is the preferred option for executing mission-critical applications and large-scale deployments due to its emphasis on enterprise-grade functionality.

CentOS's Allure

On the other hand, CentOS originated from the RHEL source code. Originally intended to be a community-driven, free substitute for RHEL, CentOS closely resembled the features of its commercial equivalent with very little change. 

Nevertheless, the CentOS Project said in December 2021 that the classic CentOS editions would no longer be supported. 

As a result, customers were left with just two choices: CentOS Stream or a deliberate switch to another distribution.

CentOS Stream: A Sneak Preview of What's to Come

RHEL is continuously delivered via CentOS Stream, which offers a rolling release approach and regular updates. For developers and testers who need to have access to the most recent RHEL packages before their official release, this method is perfect. 

However, CentOS Stream might not be appropriate for production due to its shorter lifecycle and lack of specialized support.

Considering Other Options Besides CentOS

Numerous people are considering other distributions in light of conventional CentOS being phased out. The two well-liked candidates are as follows:

  • Rocky Linux: To offer a free, open-source, and community-supported alternative to CentOS, a group of formerly employed CentOS engineers created Rocky Linux.

  • AlmaLinux, with an emphasis on long-term stability and enterprise use, is another community-driven project that aims to provide a RHEL-compatible substitute.

If you want something free that feels like CentOS, Rocky Linux, and AlmaLinux are also good choices. Making a well-informed choice will require assessing their community traction, stability, and support packages.

Selecting the Correct Course: Red Hat vs. Other Options

  • Evaluating Stability and Support First

Red Hat Enterprise Linux continues to be the clear winner when it comes to dependable stability, enduring support, and easy access to Red Hat knowledge. It offers an unparalleled level of confidence in managing critical infrastructure because of its broad ecosystem and premium support offerings.

  • Acknowledging Innovation

CentOS Stream is a very attractive choice for settings used for development and testing. Because of its frequent updates, developers can remain on top of things and always have access to the newest RHEL packages.

  • Looking for a Free Alternative

If money is a major concern, there are free, community-supported alternatives like Rocky Linux and AlmaLinux that are very compatible with RHEL. Before putting them in production settings, it's important to evaluate their long-term stability and available support.

The Final Verdict: Customize Your Selection

No one "perfect" solution exists. This is an abridged summary to assist you in making a decision:

  • Select Red Hat if: You need reliable, secure, and all-encompassing assistance. A stable platform with lengthy release cycles and assured bug patches is what you need. Access to enterprise-grade tools like Red Hat Satellite is necessary for your environment.

  • If you feel comfortable with a community-supported model and cost is a big consideration, go with Rocky Linux. It's possible for you to get access to newer features sooner and for updates to come out a little more quickly. It's possible to troubleshoot Linux issues with your competent internal IT team.

Past Rocky Linux and Red Hat

It is important to remember that Red Hat and Rocky Linux are not the only competitors in the enterprise Linux market. Rivals like SUSE Enterprise Linux (SLES) and Oracle Linux offer comparable features and capabilities. It can be beneficial to consider these options in light of your unique requirements and financial limitations.

The Last Word

Either Rocky Linux or Red Hat offer attractive, affordable options, but both provide solid bases for your server setup. By carefully weighing your needs and level of technical proficiency, you'll be able to select the ideal Linux server for your particular requirements.
