In a fast-paced tech world, it’s crucial to stay updated. 

Linux, an open-source operating system, powers many servers and websites worldwide, is known for its flexibility and security.
CentOS, a form of Linux, used by many enterprises, is now no longer the reliable, secure OS that they originally implemented.

If you’re on CentOS version 7, you’ve got until
June 30, 2024,
to plan your future with Linux.

With CentOS 7 reaching EOL in June 2024, and the alternatives often deemed impractical for most commercial uses, companies
are now left to grapple with a huge problem in their technological environments (and find a suitable alternative).

Red Hat Enterprise Linux (RHEL) is a subscription-based Linux variant that provides benefits, such as: 10 years of support, regular security patches, support calls, management features, and indemnification. Any changes Red Hat makes are contributed back to the open-source community, enriching everyone’s experience. This subscription guarantees security and stability of the OS for many years to come, as well as ___ customer support. 

Previously, CentOS offered consumers a free RHEL alternative, with CentOS receiving updates from RHEL, (with delayed availability) via the CentOS Downstream model. However, with CentOS Downstream going away, this leaves Fedora and CentOS Streams as the only free versions left. And relying on these versions has its own set of consequences. 

Below is a visual summary of how the system will change in 2024:


CentOS Stream, while technically similar to the old CentOS, is impractical for most commercial uses, due to the addition of untested changes from Fedora OS, and no software version management. Consequently, there’s no clear way to guarantee which version of the OS you’re running. Add that across multiple servers in your software environment, and you’ve got a significant problem.

Inaction can have costly consequences. Here’s what to consider:

The risks of running unsupported software: Unsupported software often equates to heightened security threats. While the software might not be critical, it’s still a potential entry point for attackers.

CentOS alternatives: While other versions are trying to fill the CentOS gap, they may lack features crucial to your operations. Thorough testing is advisable before migrating mission-critical services.

Considering RHEL: While it’s a paid solution, RHEL offers regular updates, patches, and support that ensure your mission-critical applications’ smooth running. The costs of finding an alternative or recovering from a service outage or ransom attack would likely outweigh the cost of the RHEL subscription.

In short, the shift from CentOS needs careful planning and risk assessment, but RHEL, with its robust features and support, emerges as a compelling choice.
