CentOS has long been a go-to Linux distribution for businesses, developers, and system administrators looking for a free, stable, and enterprise-grade operating system. However, with the release of CentOS Stream 8, Red Hat introduced a major shift in how CentOS operates. This transition from the traditional CentOS model to a rolling-release system sparked both excitement and concern in the Linux community.
In this article, we’ll explore CentOS Stream Release 8, its features, benefits, drawbacks, and what this means for long-time CentOS users.
What is CentOS Stream?
CentOS Stream is a continuously updated, rolling-release distribution Centos Stream Release 8 that sits between Fedora (a cutting-edge Linux distribution) and Red Hat Enterprise Linux (RHEL). Unlike previous versions of CentOS, which were built as a downstream clone of RHEL, CentOS Stream acts as an upstream distribution, providing a preview of the next minor RHEL updates before they are officially released.
This shift means CentOS Stream is no longer a 1:1 rebuild of RHEL, but rather a development branch that sits just ahead of RHEL’s stable releases.
Why the Shift to CentOS Stream?
Red Hat made the decision to transition CentOS to a rolling-release model in order to:
Improve Collaboration – CentOS Stream allows developers and businesses to contribute to the RHEL ecosystem by testing and providing feedback before updates are finalized.
Faster Feature Deployment – Since it is continuously updated, CentOS Stream receives new features and security patches faster than traditional CentOS releases.
Align with Red Hat’s Vision – Red Hat wanted CentOS to act as a preview platform for upcoming RHEL updates, ensuring better stability for enterprise users.
Key Features of CentOS Stream 8
1. Rolling-Release Model
Unlike previous versions of CentOS, which only received updates after they were incorporated into RHEL, CentOS Stream 8 gets updates continuously. This makes it an evolving platform that always includes the latest improvements.
2. Early Access to RHEL Updates
Users of CentOS Stream 8 can test upcoming RHEL updates before they are officially released. This is beneficial for developers who need to ensure software compatibility with future RHEL versions.
3. Strong Integration with the Red Hat Ecosystem
Since CentOS Stream is now the development branch for RHEL, it integrates closely with Red Hat’s ecosystem, making it easier for businesses to migrate to RHEL when needed.
4. Enhanced Security and Bug Fixes
With continuous updates, CentOS Stream 8 receives frequent security patches and bug fixes, reducing vulnerabilities and improving system stability.
5. Active Community Engagement
Red Hat encourages contributions from developers and businesses using CentOS Stream, leading to an active and engaged user base that influences RHEL’s future development.
Benefits of CentOS Stream 8
1. Access to the Latest Features
CentOS Stream 8 users can test new features before they are included in RHEL, making it a great choice for those who want cutting-edge updates while maintaining enterprise-level stability.
2. Better Bug Reporting and Fixes
Since CentOS Stream 8 acts as a testing ground for RHEL, issues can be identified and resolved faster compared to traditional CentOS versions.
3. Ideal for Development and Testing
Developers building software for RHEL can use CentOS Stream 8 to ensure their applications will work on future RHEL versions.
Drawbacks of CentOS Stream 8
While CentOS Stream 8 offers many benefits, it may not be suitable for everyone. Here are some concerns raised by users:
1. No Longer a True RHEL Clone
Many businesses relied on CentOS as a free alternative to RHEL because it was a stable, downstream clone. With the switch to an upstream model, CentOS Stream 8 no longer provides the same level of stability.
2. Frequent Updates Could Lead to Instability
Since CentOS Stream is a rolling-release distribution, new updates could introduce bugs or compatibility issues that would not have existed in the old CentOS model.
3. Enterprises May Need to Switch to RHEL
Businesses that relied on CentOS for mission-critical applications may now need to consider migrating to RHEL or alternative distributions to ensure long-term stability.
Alternatives to CentOS Stream 8
For users who are not comfortable with the rolling-release model of CentOS Stream 8, several alternatives have emerged:
1. Rocky Linux
Created by Gregory Kurtzer, the original founder of CentOS, Rocky Linux is a 1:1 downstream rebuild of RHEL, offering a stable alternative for users who preferred the old CentOS model.
2. AlmaLinux
Backed by CloudLinux, AlmaLinux is another RHEL-compatible distribution designed to replace traditional CentOS. It is widely supported and provides long-term stability.
3. Oracle Linux
Oracle Linux offers full RHEL compatibility with additional enterprise-grade enhancements. It is free to use, with optional paid support.
4. Debian or Ubuntu LTS
For users who are open to non-RHEL-based alternatives, Debian and Ubuntu LTS provide stable and secure Linux environments widely used in enterprise settings.
Should You Use CentOS Stream 8?
CentOS Stream 8 is an excellent choice for:
Developers who want to test applications against upcoming RHEL versions.
Businesses that need early access to RHEL updates.
System administrators who are comfortable managing frequent updates.
However, if you require a rock-solid, unchanging system like the old CentOS versions, you may be better off with Rocky Linux or AlmaLinux.
Final Thoughts
CentOS Stream Release 8 marks a significant shift in the Linux ecosystem, moving Centos Stream Release 8 away from a stable, downstream model to a continuously evolving upstream model. While it offers benefits like early access to RHEL features and faster updates, it also introduces concerns about stability and predictability.
For those willing to embrace the rolling-release nature of CentOS Stream, it provides a powerful and forward-thinking Linux environment. However, for businesses and users needing a traditional, stable CentOS experience, alternatives like Rocky Linux and AlmaLinux are the best options.
The CentOS landscape has changed, and the choice now depends on what you need from your operating system.
