Executive SummaryUpdated on Aug 3, 2025

CentOS and Rocky Linux are competing in the open-source operating systems space for enterprise-level needs. Rocky Linux seems to have the edge in compatibility and long-term stability, making it a compelling choice for reliable performance.

Features: CentOS offers excellent integration with Red Hat systems, prioritizes security, and has a robust community. Rocky Linux maintains 1:1 compatibility with Red Hat Enterprise Linux, ensures a seamless transition from CentOS, and emphasizes continuity and reliability.

Room for Improvement: CentOS could improve on providing clarity about its future support, expand its documentation to assist new users, and enhance user interface simplicity. Rocky Linux might focus on expanding its support network, streamlining its deployment process for new users, and enhancing integration with other enterprise tools.

Ease of Deployment and Customer Service: CentOS has established deployment procedures and extensive documentation, making it straightforward for seasoned administrators. In contrast, Rocky Linux offers a similar deployment model with community-driven customer service that aims to fill gaps left by CentOS's discontinued full support. Despite a learning curve, its support channels are responsive and welcoming to migrating users.

Pricing and ROI: CentOS is cost-effective with a zero-cost purchase model, though indirect costs may appear due to maintenance and training. It historically provided substantial ROI through stability and community support. Rocky Linux also offers a no-cost model promoting reduced indirect costs due to its straightforward migration path from CentOS, aiming to maximize ROI by minimizing transition costs and leveraging existing investments.

In-depth documentation available and command-line utility works well

One issue I recently faced, but I think it was due to my IT support guys, was that when the server storage gets full, the service crashes. It's very difficult to regain access and stability in that situation. That could be improved. So, the stability might be improved. But I don't think it's a CentOS-level issue. The system administrators need to come up with a solution for that, but I don't think it's CentOS's fault. I haven't done any research [R&D] on this issue. There's one thing for sure. We recently migrated from CentOS 7 to CentOS 9, and it was a bit difficult. For example, updating Windows is simple; you just download it, and it takes about 15-20 minutes. But that's not the case with migrating from CentOS 7 to 9. We had to back up the entire server, launch a new server, and then restore the backup to the new server. We couldn't directly migrate. I think that was a bit of a problem. The setup and updates are not that new in CentOS.

Overview

CentOS offers a stable, secure, and compatible environment with Red Hat packages, providing robust performance and cost efficiency. Its lightweight, scalable design and strong community support make it ideal for handling heavy workloads with limited resources.

CentOS is a popular choice for organizations seeking reliable server and virtualization solutions. Known for its robust stability and security, it offers seamless integration and maintenance. However, after a shift from Red Hat, some challenges emerged, including weak NFS client performance and a more complex interface, which beginners find challenging alongside insufficient documentation. Despite these, CentOS remains a favored option for deploying web applications, server installations, and supporting cloud solutions, thanks to its efficient use in monitoring, databases, and telecommunications.

What are CentOS's key features?

Stability: Maintains a consistent performance, essential for mission-critical environments.
Security: Offers robust safeguards, aligning with Red Hat's trusted security packages.
Compatibility: Seamlessly integrates with Red Hat ecosystems, enhancing versatility.
Cost Efficiency: Open-source approach reduces expenses compared to proprietary systems.
Community Support: Access to extensive resources and assistance from a dedicated user base.

What benefits should users look for in reviews?

Performance: Efficient resource management even under heavy workloads.
Integration Ease: Smooth integration with existing IT infrastructures.
Scalability: Ability to grow with changing requirements, supporting diverse applications.
Flexibility: Adaptable to a wide range of industries and use cases.
Reliability: Trusted for critical operations and consistent service delivery.

CentOS is widely used in industries requiring robust infrastructure, such as web hosting, scientific computing, and telecommunications. In data centers, companies deploy it to support virtual environments, testing, and development. The OS powers business applications, email servers, and cloud solutions, offering a cost-effective alternative to Red Hat.

CentOS

Rocky Linux is a robust and secure enterprise-grade operating system designed as a drop-in replacement for CentOS. Its primary use case is to provide a stable and reliable platform for organizations to run their critical workloads and applications.

The most valuable functionality of Rocky Linux lies in its compatibility with CentOS, ensuring a seamless transition for organizations already using CentOS. It offers long-term support, regular security updates, and a predictable release cycle, providing stability and reliability for mission-critical systems.

Rocky Linux helps organizations by offering a free and open-source alternative to CentOS, which was discontinued by Red Hat. It allows businesses to continue using their existing CentOS-based infrastructure without the need for costly migrations or vendor lock-in. With its strong community support and active development, Rocky Linux ensures a sustainable and community-driven future for CentOS users.

Moreover, Rocky Linux is built with security in mind, providing robust features like SELinux and secure defaults. This helps organizations protect their data and systems from potential threats and vulnerabilities.
