Almalinux Vs. Rocky Linux: Centos Successors

AlmaLinux vs. Rocky Linux: CentOS Successors

CentOS (Community Enterprise Operating System), a popular Linux distribution for servers, faced an uncertain future in 2024 when its parent company, Red Hat, announced changes to its lifecycle. This prompted the creation of two new CentOS successors: AlmaLinux and Rocky Linux. Both distributions aim to continue the legacy of CentOS, providing a stable and enterprise-grade platform for servers.


  • Upstream Compatibility: Both AlmaLinux and Rocky Linux are source-compatible with Red Hat Enterprise Linux (RHEL), the commercial upstream of CentOS. This ensures compatibility with a wide range of software packages and applications certified for RHEL.
  • Community-Driven: AlmaLinux and Rocky Linux are community-supported distributions with development efforts driven by contributors from around the globe. They strive to be open, transparent, and responsive to user feedback.
  • Long-Term Support: AlmaLinux and Rocky Linux offer long-term support (LTS) releases, with security and maintenance updates available for extended periods (up to 10 years). This provides stability and predictability for critical server environments.


  • Support Model: AlmaLinux offers enterprise-level support through subscription plans, providing access to professional support engineers and priority updates. Rocky Linux, on the other hand, relies solely on community support through its extensive online forums and documentation.
  • Development Focus: AlmaLinux places a stronger emphasis on security and stability, with regular security audits and a conservative approach to new features. Rocky Linux aims to provide a more cutting-edge distribution, with a focus on innovation and the integration of new technologies.
  • Preservation of RHEL Value: AlmaLinux explicitly supports the “Red Hat Value” model, which ensures interoperability with RHEL certified software and licensing. Rocky Linux takes a more open stance, allowing users to mix and match software from multiple sources.

Choosing Between AlmaLinux and Rocky Linux

The choice between AlmaLinux and Rocky Linux depends on specific needs and preferences.

  • Stability and Security: For critical server environments requiring maximum stability and security, AlmaLinux with its enterprise support and focus on preservation of RHEL value might be a better option.
  • Innovation and Openness: For organizations seeking a more cutting-edge distribution with greater flexibility in software sourcing, Rocky Linux’s focus on innovation and its open support model could be advantageous.## Almalinux Vs. Rocky Linux: CentOS Successors

Executive Summary

Almalinux and Rocky Linux are two popular Linux distributions that have emerged as successors to the widely used CentOS distribution. Both distributions aim to provide a stable and reliable platform for enterprise and production environments. However, there are some key differences between the two distributions that users should consider when choosing the best option for their needs.


CentOS, a popular Linux distribution based on Red Hat Enterprise Linux (RHEL), was discontinued in December 2024. This led to the creation of several new distributions, including Almalinux and Rocky Linux, which aim to fill the void left by CentOS. Both distributions are community-supported and offer long-term support, making them attractive options for businesses and individuals who rely on stable and reliable operating systems.

Key Differences

1. Origin and Development

  • Almalinux: Created by CloudLinux, a company known for its Linux operating system for web hosting.
  • Rocky Linux: Created by the Rocky Enterprise Software Foundation, a non-profit organization led by Gregory Kurtzer, the founder of CentOS.

2. Package Management

  • Almalinux: Uses the yum package manager, which is also used by RHEL and CentOS.
  • Rocky Linux: Uses the dnf package manager, which is also used by Fedora.

3. Support

  • Almalinux: Backed by CloudLinux, which provides commercial support and managed services.
  • Rocky Linux: Supported by the Rocky Enterprise Software Foundation, which relies on community contributions.

4. Release Cycle

  • Almalinux: Releases occur on the same schedule as RHEL, approximately every two years.
  • Rocky Linux: Releases occur on a shorter cycle, approximately every six months.

5. Security Updates

  • Almalinux: Security updates are typically released within 24 hours of the upstream release.
  • Rocky Linux: Security updates are typically released within 90 days of the upstream release.


Both Almalinux and Rocky Linux are strong contenders to replace CentOS as a stable and reliable enterprise-grade Linux distribution. Almalinux offers a higher level of commercial support, while Rocky Linux provides more frequent releases and a shorter security update turnaround time. Ultimately, the best choice for users depends on their specific needs and preferences.
