Differance between Alma linux and Centos in the prospective of Whm/Cpanel

As of my last knowledge update in September 2021, both AlmaLinux and CentOS are Linux distributions that are often used in server environments, particularly for hosting purposes with cPanel and WHM (WebHost Manager). However, there have been significant changes in the CentOS ecosystem since then, so it's important to verify the most up-to-date information.

Background:
- CentOS: CentOS (Community ENTerprise Operating System) was known for its close relationship to Red Hat Enterprise Linux (RHEL). It aimed to provide a free and open-source alternative with RHEL's stability and compatibility.
- AlmaLinux: AlmaLinux was created as a response to the announcement by Red Hat that they would be shifting their focus from CentOS Linux to CentOS Stream. AlmaLinux's goal was to provide a drop-in replacement for CentOS Linux, maintaining its compatibility and stability.
Source of the Distribution:
- CentOS: CentOS was a downstream distribution of RHEL, which means it was built from the source code of RHEL after it had been released.
- AlmaLinux: AlmaLinux is a fork of RHEL, not derived from CentOS. It's developed by the creators of CloudLinux.
Version Compatibility:
- CentOS: CentOS traditionally aimed for binary compatibility with RHEL, meaning software built for RHEL should work on CentOS without modification.
- AlmaLinux: AlmaLinux also aims to be binary-compatible with RHEL.
Support and Updates:
- CentOS: Previously, CentOS had a reputation for long-term support and stability, with updates released after RHEL updates.
- AlmaLinux: AlmaLinux follows a similar approach, offering long-term support and regular updates.
cPanel and WHM Compatibility:
- CentOS: Historically, cPanel and WHM have been well-supported on CentOS, and many hosting providers used CentOS as the base OS for their cPanel servers.
- AlmaLinux: As of my last update in September 2021, AlmaLinux was actively working to ensure compatibility with cPanel and WHM. The AlmaLinux team aimed to provide support for cPanel users.
Migration and Transition:
- CentOS: The change in the CentOS ecosystem, particularly the introduction of CentOS Stream, led many users to consider alternatives due to concerns about stability and compatibility.
- AlmaLinux: AlmaLinux positioned itself as a direct replacement for CentOS, offering a migration path for users who wanted to switch to a distribution that was more similar to the traditional CentOS model.

Since the landscape of Linux distributions and their compatibility with specific software can change rapidly, I recommend checking the latest information on the official websites of both AlmaLinux and cPanel/WHM, as well as any relevant community forums or discussions, to get the most accurate and up-to-date information about compatibility and support.
