The success of a Linux distribution can be measured through several metrics: community adoption, quality of support, speed of implementing updates and patches, and ability to respond to user needs. In the case of so-called “RHEL clones,” the issue becomes even more complex, given that these are distributions that must balance compatibility with Red Hat Enterprise Linux (RHEL) with offering added value that justifies their existence.
AlmaLinux is one such distribution, which emerged strongly after Red Hat's decision in 2020 to discontinue CentOS as a stable clone of RHEL. However, AlmaLinux stood out not only for its rapid adoption but also for its unique approach, avoiding initiatives like OpenELA (the association created by CIQ, SUSE, and Oracle to share compatible RHEL sources) and maintaining its own identity by ensuring ABI (Application Binary Interface) compatibility with RHEL.
The Exponential Growth of AlmaLinux Mirrors
A concrete example of AlmaLinux's success is its mirror network, which went from just one mirror to over 400 in just a few years. Already in 2021, the number of mirrors had exceeded one hundred, but it is in the following years that the project has seen exponential growth, thanks to an unprecedented community commitment. This global network of mirrors is not only a sign of the diffusion of AlmaLinux, but also reflects the organizational capacity of its community, which has been able to coordinate and collaborate to make the distribution available in every corner of the world.
What is striking in this evolution is the collaborative spirit that guided every step of the process. From tech giants like AWS, who recognized the importance of AlmaLinux's installed base and implemented a dedicated mirror system, to universities who made their servers and bandwidth available, every contribution played a role crucial. This level of cooperation is rare in open-source projects of this scale and is a testament to the strength of the community that supports AlmaLinux.
Innovation and Differentiation: The Mirroring System
In addition to the growth in the number of mirrors, AlmaLinux has also differentiated itself through technological innovation. The mirror synchronization system was designed to ensure the best possible performance, an aspect that has been recognized by users as one of the distribution's strengths . This is not just a technical detail, but represents a concrete example of how the AlmaLinux community has placed efficiency and usability at the center of its work.
This focus on innovation continues to be a priority for AlmaLinux, as demonstrated by the long list of objectives still to be achieved. The project's "TODO list" is a testament to the fact that the community has no intention of stopping here, but rather, plans to continue to improve and innovate, ensuring that AlmaLinux remains one of the most relevant and reliable distributions in the RHEL clone landscape .
FIPS 140 certified
Response Capacity: Quick Patches and Bug Fixes
Another plus for AlmaLinux is its ability to respond quickly to vulnerabilities and security issues. A prime example is the handling of CVE-2024-1086, a vulnerability that was patched in AlmaLinux even before RHEL . This was possible thanks to AlmaLinux's ABI compatibility, which allowed the community to take action independently, without having to wait for Red Hat's intervention.
But it is not only in security issues that AlmaLinux has demonstrated its reactivity. Even in less critical areas, such as fixing bugs in niche software, the distribution has been able to stand out. An interesting case is that of a bug in special effects software, a problem that did not have a high priority for Red Hat, but which the AlmaLinux community was able to quickly resolve thanks to the coordinated work of its members. This shows how the strength of the community can make a difference, even in situations that might seem marginal.
AlmaLinux: A solid present and a promising future
The impressive growth and ability to solve problems quickly are positive signs for the future of AlmaLinux. The community has demonstrated that it has not only the technical skills, but also the motivation and organization necessary to face the challenges that arise.
Time will tell if AlmaLinux can maintain this momentum and consolidate its position as one of the leading Linux distributions in the RHEL clone landscape. However, the foundations for a long success story are there. The distribution has not only earned the attention and respect of the global community, but has also proven itself to offer a valid and reliable alternative to RHEL, with a unique approach and a strong identity.
AlmaLinux is a brilliant example of how a united community can achieve extraordinary results. The project continues to grow, and with it, the trust of the users and developers who rely on it. If recent history is any indicator, AlmaLinux has all it takes to become a pillar of the Linux world, supported by a community that has proven to work wonders.
