If you’ve been running CentOS and felt thrown off by its recent shift to AlmaLinux you’re not alone! It has left users searching for a reliable, stable, alternative. And that’s where AlmaLinux enters, which is considered a no-drama alternative. It is designed to manage servers, develop apps, or run a business, providing stability and predictability that runs this OS smoothly.
In this article, we’re talking about how AlmaLinux vs CentOS can be compared, based on their unique and distinctive features. Moreover, Why should an admin upgrade their operating systems? So let’s explore which is the better OS.
The CentOS Shift: What Happened and Why It Matters
Let’s understand the ContOS shift and what EOL means.
Now for years, CentOS is a Linux distribution that has been the backbone of countless enterprise servers and compatibility with REHL.
CentOS offers a free and open-source platform supported by the community, and it is functionally aligned with its upstream partner, Red Hat Enterprise Linux (RHEL).
As CentOS 8 reached its End of Life (EOL) on Dec 31, 2021, and CentOS Stream took over. However many users who always valued CentOS for stability and long-term support are now facing the challenge of transitioning. Leaving them with limited support options.

WHY EOL MATTERS?
When an operating system hits its end of life, it stops getting:
- Security updates: This puts systems at risk of attacks.
- Bug fixes: This increases the cases of operational issues.
- Official support: This complicates troubleshooting efforts.
- For companies that rely on vital systems, staying with an outdated OS like CentOS 8 just isn’t feasible.
Here are the official dates on the CentOS official Site, where the EOL coming dates for CentOS 8 and CentOS 7 were released.
What Is AlmaLinux?
AlmaLinux OS is a community-focused, free open-source Linux operating system that stepped in after CentOS Linux stopped its stable releases. It’s an Enterprise Linux distribution that’s fully compatible with RHEL®, developed and supported by the community.
AlmaLinux vs CentOS serves as a free alternative to CentOS, created by the CloudLinux team. Since CloudLinux is a downstream version of RHEL, they have a solid background in maintaining an RHEL clone.
The AlmaLinux Foundation will ensure that the project remains community-driven. The software in AlmaLinux is designed to be 1:1 binary compatible with both RHEL and the non-stream version of CentOS.
Switching from CentOS and other RHEL® derivatives to AlmaLinux OS incurs no costs or time commitments, which is different from the typical migration process for distributions.
