With the discontinuation of CentOS 8 at the end of 2021 and the shift to CentOS Stream, many server administrators and developers have been seeking a stable, long-term alternative. AlmaLinux has emerged as one of the most promising options, offering a reliable, free, and open-source solution that’s fully compatible with Red Hat Enterprise Linux (RHEL). Here’s why AlmaLinux is an excellent choice over CentOS for your server environment.
1. True CentOS Replacement with Long-Term Stability
AlmaLinux was created with the mission of providing a 1:1 binary-compatible fork of RHEL, much like CentOS originally did. As an RHEL-compatible distribution, it gives users a familiar, stable environment without the rolling-release model that CentOS Stream now follows. With the same structure, commands, and behavior as RHEL, AlmaLinux ensures that users experience minimal disruption while switching from CentOS.
2. Community-Driven and Open Source
AlmaLinux was founded and is maintained by the non-profit AlmaLinux OS Foundation, making it a community-driven project. This structure fosters transparency and community input, giving users a stake in the project’s direction. Unlike CentOS Stream, which is now a rolling pre-release for RHEL, AlmaLinux commits to remaining a stable release compatible with RHEL, driven by community contributions and feedback.
3. Free to Use with No Licensing Fees
AlmaLinux is completely free to use, with no hidden fees or licensing requirements, similar to CentOS. This makes it an attractive choice for businesses, organizations, and individuals who need a robust, enterprise-grade OS without the costs associated with RHEL subscriptions.
4. Extended Support and Long-Term Viability
AlmaLinux OS Foundation has pledged to provide long-term support for AlmaLinux, with updates and patches planned for 10 years, much like RHEL’s lifecycle. This extended support gives businesses peace of mind that they won’t need to switch operating systems frequently and allows for long-term planning and stability.
5. Easy Migration Tools and Guides for CentOS Users
Switching from CentOS to AlmaLinux is straightforward, thanks to the migration tools developed by the AlmaLinux OS Foundation. For users already on CentOS 8, the foundation provides AlmaLinux-deploy, a script that simplifies the migration process by converting an existing CentOS system to AlmaLinux without a full reinstallation. This ease of migration allows businesses to transition with minimal downtime and without costly, time-consuming reconfiguration.
6. Security and Reliability
AlmaLinux maintains rigorous security standards to provide a secure operating system. Regular updates and patches keep the system safe from vulnerabilities, and since it’s built to mirror RHEL, you can expect enterprise-grade stability and security features. For users concerned with CentOS Stream’s potential lack of stability, AlmaLinux offers the peace of mind that comes with a fully stable release model.
7. Wide Compatibility and Support for Enterprise Applications
Since AlmaLinux is designed to be fully RHEL-compatible, it works seamlessly with most applications and software built for RHEL. Many enterprise applications that ran on CentOS 7 and 8 will work without issue on AlmaLinux. This compatibility makes it easy to adopt without needing to alter existing software or configurations.
8. Active and Growing Community Support
AlmaLinux’s community is growing quickly, with active forums, extensive documentation, and support channels to help users troubleshoot and optimize their setups. As an open-source community project, AlmaLinux benefits from the collaboration of developers, businesses, and users, ensuring that AlmaLinux remains resilient and adaptable.
9. Endorsements and Contributions from Major Organizations
Major organizations in the tech industry, including CloudLinux, have endorsed AlmaLinux and are contributing to its development. This backing by established companies provides additional assurance that AlmaLinux is a sustainable, reliable option for production environments. These organizations also contribute resources and expertise to AlmaLinux, ensuring it stays aligned with the needs of enterprise users.
Conclusion: AlmaLinux as the Next Step for CentOS Users
AlmaLinux offers everything that made CentOS great—stability, RHEL compatibility, and cost-effectiveness—while remaining free and open-source. Its commitment to stability and long-term support, backed by a strong community, makes it an ideal choice for businesses looking to transition smoothly from CentOS without compromising on performance or reliability. For server administrators and developers seeking a trusted CentOS successor, AlmaLinux is a compelling, future-proof solution.
