As CentOS 7 reaches its end of life (EOL) on Sunday, an era in enterprise Linux computing is coming to a close. Users are now faced with the critical decision of choosing the right path forward for their systems. The announcement was anticipated, yet it has sent ripples through the tech community. The subsequent discussion is rife with varying opinions on the best course of action, each informed by individual experiences, preferences, and an ever-evolving landscape of enterprise Linux distributions.
Many users have turned to CentOS Stream, a rolling-release Linux distribution that sits upstream of Red Hat Enterprise Linux (RHEL). One commentator noted that the five-year lifecycle of CentOS Stream reassured them, while another humorously pointed out its coincidental acronym similarity with SUSE’s Leap. CentOS Stream offers an opportunity for those who want a more stable, RHEL-like experience but with more frequent updates. However, its rolling release nature isn’t a one-size-fits-all solution, especially for enterprises with strict change management policies. You can learn more about CentOS Stream from Red Hat’s detailed guide here.
The shifting landscape has also driven a significant number of enterprises towards alternatives like AlmaLinux and Rocky Linux. AlmaLinux, noted by many, has seamlessly picked up the mantle of CentOS 7, offering communities and enterprises a free, open-source, and enterprise-grade operating system. One user praised it as an ideal solution, saying, ‘Alma Linux user here, happy with it, everything works.’ AlmaLinux is backed by CloudLinux, which assures longevity and stability, crucial for businesses making long-term decisions.

Similarly, Rocky Linux, another CentOS derivative, has garnered acclaim. Notable for its mission to be binary-compatible with RHEL, Rocky Linux has resonated well with users who prefer stability and longevity similar to CentOS 7. One enthusiastic comment highlighted how smooth the transition was, stating, ‘The transition was very smooth.’ However, some users reported different experiences, especially with highly customized installations or specific scientific computing requirements, where ensuring exactness and reliability remains paramount. As mentioned in our recent editorial, you can explore more about Rocky Linux on its official website here.
Interestingly, another significant discourse emerges around the suitability of Debian-based distributions as alternatives to CentOS. Debian and its derivatives, such as Ubuntu Server, have long been trusted by users who value the controlled cadence of updates and the exceptional community support they offer. Debian was praised for its reliability and straightforward update mechanisms, thus appealing to those looking for a more traditional release model while still benefiting from robust security and stability. One compelling insight was shared by a user stating, ‘Upgrading the OS is easy. Initial work is a couple of days, rest of the deployment is an hour or so.’ This sentiment underscores the flexibility and resilience of Debian and its ecosystem.
Opinions diverge as some users contemplate enterprise-level Linux distributions like Oracle Linux and SUSE Liberty Linux. Oracle Linux is commended for its swift patching cycles, which ensures that security vulnerabilities are addressed promptly, a vital consideration for any enterprise. However, concerns about vendor lock-in and long-term commitment to Oracle’s ecosystem are not uncommon. SUSE, on the other hand, offers Liberty Linux, an intriguing option for those looking to transition with minimal disruptions. As SUSE continues to innovate, one user wittily remarked on the irony of SUSE playing a pivotal role in maintaining a lifeline for CentOS users.

As the tech world transitions from CentOS 7, the path forward is clear yet varied. Enterprises need to carefully evaluate their specific requirements, potential risks, and the long-term support model of the alternatives they are considering. With numerous robust options available—from CentOS Stream, AlmaLinux, and Rocky Linux to Debian and Oracle Linux—the future of enterprise Linux remains bright. Whichever path is chosen, the key lies in thorough planning, testing, and a community-driven approach to ensure a seamless transition and continued success in operations.
