What’s the Future of CentOS? A Deep Dive into Its Evolution and Alternatives

CentOS History

Linux, backed by major companies such as IBM, Intel, Oracle and others, has spawned over three hundred distributions, with the most popular including Fedora, Debian, Ubuntu, Red Hat and CentOS. Distributions fall into two categories: commercially maintained (e.g., Red Hat Enterprise Linux) and community‑maintained (e.g., Debian). In China, CentOS dominates because it sits at the downstream end of the Red Hat ecosystem (Fedora → RHEL → CentOS).

Fedora serves as a testing ground for new features; Red Hat incorporates those features into RHEL, which requires a costly subscription. CentOS rebuilds RHEL from source after removing trademarked components, offering the same stability for free.

In 2019, Red Hat introduced CentOS Stream, moving the community focus upstream. CentOS Stream is a developer‑oriented release that aims to provide a more predictable and innovative Linux ecosystem.

Current Status of CentOS

CentOS Linux 8 stopped receiving updates at the end of 2021. CentOS Linux 7, which has the largest user base, will reach end‑of‑support on 30 June 2024. No new CentOS Linux releases will be made; only CentOS Stream will continue to evolve.

Red Hat recommends that existing CentOS users begin migration planning early, choosing a path that fits their production needs.

Migration Paths and Alternatives

Common alternatives include:

1. Ubuntu/Debian

Ubuntu offers a large community, extensive documentation, and LTS releases every two years with nine‑month support for standard releases, making it suitable for internet‑scale workloads such as AI, compilation environments and big data.

2. Oracle Linux

Built from RHEL source code, Oracle Linux is essentially a clone of Red Hat Linux and provides early security updates.

3. openSUSE

Features three package managers (ZYpp, YaST, RPM) and follows a release cadence similar to Ubuntu, with minor releases yearly and major releases every 3–4 years.

4. Rocky Linux

Founded by CentOS co‑founder Gregory Kurtzer, Rocky Linux aims for 100 % compatibility with RHEL.

5. Domestic Distributions

OpenEuler – optimized for cloud, containers, virtualization and confidential computing.

Anolis OS – fully open‑source, 100 % compatible with CentOS 8, supports multiple architectures.

Alibaba Cloud Linux 3 – derived from Anolis OS and tuned for Alibaba Cloud infrastructure.

TencentOS Server Kernel – designed for cloud scenarios with performance and security enhancements.

KylinOS – targets enterprise workloads, supporting domestic CPUs and various hardware platforms.

Red Flag Linux – desktop‑oriented, supports multiple instruction sets and provides container management tools.

Enterprises seeking a CentOS replacement should consider Red Hat Enterprise Linux for maximum compatibility, while many internet‑scale companies prefer Ubuntu for its rapid innovation cycle. Using CentOS Stream is also viable, as it follows Red Hat’s rigorous testing process.

Opportunities for Domestic Operating Systems

Chinese open‑source communities are rapidly advancing, aligning hardware and software development. Projects such as OpenEuler, Anolis OS, Alibaba Cloud Linux, TencentOS, KylinOS and Red Flag Linux aim to provide fully autonomous, high‑performance, and secure operating systems for a wide range of workloads, from data centers to edge devices.
