When CentOS shifted to CentOS Stream, users seeking stability began searching for reliable replacements. Two prominent contenders emerged: AlmaLinux and Rocky Linux. Both offer RHEL compatibility and promise long-term support, but which one is better suited for your needs? In this in-depth comparison of Rocky Linux vs AlmaLinux, we’ll explore their backgrounds, development models, and stability to help you make an informed decision between AlmaLinux or Rocky Linux.
The Origins: AlmaLinux and Rocky Linux
AlmaLinux and Rocky Linux were both created as direct responses to Red Hat’s shift with CentOS. This change from a stable release model to a rolling-release left users looking for enterprise-ready alternatives.
AlmaLinux, developed by CloudLinux, is backed by a company with years of experience in delivering commercial Linux distributions. Its launch was fast-tracked to provide users with a quick, stable solution following the CentOS announcement.
Rocky Linux, on the other hand, was founded by Gregory Kurtzer, the original creator of CentOS. Rocky Linux’s goal was to restore a community-centric approach, ensuring a free and open-source solution similar to the traditional CentOS model. Named after Rocky McGaugh, a co-founder of CentOS, Rocky Linux continues the legacy of CentOS in a community-driven format.
Development Model: Corporate Backing vs. Community-Driven
One of the biggest distinctions between AlmaLinux and Rocky Linux is their development approach.
Rocky Linux is entirely community-led. The decisions about the operating system, updates, and future features are made by contributors and users. This ensures transparency and a user-first approach, which appeals to those who prefer the ethos of open-source collaboration.
In contrast, AlmaLinux benefits from the commercial backing of CloudLinux. While there is still strong community involvement, AlmaLinux benefits from financial support, structured development, and professional resources that help ensure stability and rapid updates. This makes it a great option for businesses and enterprises that need reliable long-term support.
Stability and Security: AlmaLinux vs Rocky Linux
Both AlmaLinux Rocky Linux promise the same level of RHEL compatibility and follow RHEL’s release cycle. This ensures that both distributions offer stability, security, and reliable performance.
One of AlmaLinux’s advantages is its access to the commercial resources of CloudLinux. This allows AlmaLinux to deliver timely updates and security patches with a structured release model, making it a go-to choice for enterprises that require prompt responses to security threats.
Meanwhile, Rocky Linux, despite its community-driven nature, has proven to be efficient in maintaining its release schedule and delivering security patches. The active Rocky Linux community ensures that updates are rolled out swiftly, providing a reliable solution for users who prefer to rely on community-driven development.
Performance: How Do They Compare?
In terms of performance, AlmaLinux and Rocky Linux offer nearly identical functionality, as both are binary-compatible with RHEL. This means they deliver the same level of performance for enterprise workloads, server environments, and software development.
Choosing between AlmaLinux vs Rocky Linux boils down to your personal preferences.
Rocky Linux attracts users who prefer the open-source community model, where transparency, collaboration, and user control are top priorities. The project is shaped entirely by its user base, providing a sense of ownership over its future direction.
AlmaLinux, on the other hand, offers the added reliability of CloudLinux’s commercial backing. This ensures faster updates and long-term viability, making AlmaLinux the ideal choice for those who want enterprise-grade stability without compromising on community involvement.
Long-Term Viability: Which One Is More Sustainable?
The long-term viability of both AlmaLinux and Rocky Linux is solid, but they are supported in different ways.
AlmaLinux benefits from CloudLinux’s backing, giving it the financial support and professional expertise necessary to ensure its longevity. This gives users confidence that AlmaLinux will continue to receive regular updates, patches, and support for years to come.
Rocky Linux, while relying on its community, has demonstrated strong momentum since its launch. The Rocky Linux community is passionate and dedicated to its long-term success. This community-driven model ensures that the project remains focused on user needs and maintains its open-source roots.
Migration from CentOS: Seamless Transitions
For CentOS users, both AlmaLinux and Rocky Linux provide easy migration tools to transition smoothly from CentOS. These tools ensure minimal downtime and minimal configuration changes, making it simple to switch over.
The documentation and support for both distributions are extensive, so migrating to AlmaLinux or Rocky Linux is a straightforward process.
Conclusion:
The final decision between AlmaLinux and Rocky Linux depends on what you prioritize.
If you’re someone who values the open-source community ethos and wants a community-driven project with no corporate influence, Rocky Linux is your perfect match. It’s built for users who want to continue the CentOS mission of providing a free and collaborative Linux distribution.
