What does the EOL Mean in Practical Terms?
CentOS end-of-life status indicates the end of official support and updates from the CentOS project. In practice, this implies that no additional security patches, bug fixes, or software upgrades will be released for the operating system. Without continued support, CentOS systems are more exposed to security risks and compatibility difficulties. Businesses and server managers who rely on CentOS have considerable hurdles and must plan carefully to ensure the stability and security of their systems.
What if I use CentOS 8?
Centos EoL what does the end mean for users centos 8? If you're currently using CentOS 8, the end-of-life notification may have come as a surprise, as CentOS 8's support lifespan was shockingly short. With this development, CentOS 8 customers are left with few options. They can either continue to use CentOS 8 without official support, potentially exposing their systems to security risks, or they can look into alternative solutions such as migrating to CentOS Stream, switching to another Linux distribution, or exploring enterprise options such as Red Hat Enterprise Linux (RHEL) or its downstream derivative, AlmaLinux.
What if I use CentOS 7?
On the other hand, if you're using CentOS 7, the end-of-life announcement doesn't cause immediate alarm because CentOS 7 will continue to receive updates and support until its anticipated end-of-life in 2024. However, it is critical to begin planning for the eventual move to a supported platform well in advance to avoid last-minute rushes or disruptions to your operations. Whether you want to migrate to CentOS Stream, upgrade to CentOS 8 (if possible), or investigate alternative distributions, having a well-planned migration strategy is critical to ensuring the continuity and security of your system.
What is Next for CentOS?
Several alternate pathways are emerging. One major development is the emergence of community-driven CentOS alternatives like AlmaLinux and Rocky Linux. These distributions seek to provide a stable, long-term support alternative to CentOS by remaining compatible with existing CentOS deployments while providing ongoing upgrades and security patches. Additionally, CentOS customers may consider shifting to other well-known Linux distributions such as Ubuntu, Debian, or Fedora, each with their own set of benefits and community support.

Why Was CentOS So Popular?
CentOS was very popular for a variety of compelling reasons, the most notable of which was its stability, being open source, being free, and having fewer updates. Here, we explain more why CentOS was so popular:
Stability
CentOS's success stems from its reputation for dependability, making it the preferred choice for servers and enterprise environments. CentOS was derived from the same source code as Red Hat Enterprise Linux (RHEL), and thus inherited RHEL's rock-solid performance and reliability. CentOS was prized by system administrators for its consistent release cycle and long-term support, which ensured that key systems experienced little downtime and maximum uptime.
Having an Open Source OS
CentOS, being an open-source operating system, emphasized openness, flexibility, and community engagement. Users had complete access to CentOS's source code, allowing them to change, customize, and redistribute it to meet their requirements without being bound by restrictive licensing agreements. This open nature spurred innovation and allowed people to contribute to the project, resulting in a thriving ecosystem of developers and fans.
It Was Free
CentOS's cost-effectiveness was a key factor in its adoption. CentOS, as a free alternative to commercial Linux versions, enabled enterprises to better utilize their IT budgets.
Had Fewer Updates
Furthermore, CentOS's less regular update schedule than some other distributions resulted in fewer disruptions to production settings, lowering the administrative burden involved with managing frequent updates and patches.
Why Did CentOS EoL Happen?
CentOS's end-of-life can be linked to a combination of resource restrictions and shifting priorities within the larger enterprise Linux ecosystem. While CentOS was a pillar of the open-source movement for many years, new commercial factors and user expectations demanded a rethinking of its position and viability. There are two major reasons that CentOS end of life happened:
Too Much for Too Little
Over time, CentOS grew in popularity as a downstream rebuild of Red Hat Enterprise Linux (RHEL), providing users with a free, stable option with long-term support. However, maintaining such a project necessitates substantial resources, both in terms of infrastructure and personnel. As CentOS's user base grew, the project's demands expanded disproportionately to the resources available, causing strain and difficulty in satisfying user expectations for rapid updates and support.
Side Project Hindrance
CentOS was created by volunteers to provide a free version of RHEL. It operated independently of Red Hat, relying on volunteers and little resources to survive. However, when IBM acquired Red Hat, things changed. Red Hat created CentOS Stream, which is more closely related to RHEL development. This meant less attention and support for the previous CentOS. With this change, CentOS was unable to maintain its previous style of operating due to a lack of expertise and resources.
The CentOS EOL dates for various releases are as follows:
- CentOS 6: November 30, 2020
- CentOS 7: June 30, 2024
- CentOS 8: May 2029 (planned)
- Early End of Life: December 31, 2021
Why is CentOS EoL Such A Big Deal?
Some reasons show CentOS EoL is a big deal:
- Longevity and stability: CentOS has a reputation for long-term support and reliability. Many enterprises, particularly in enterprise environments, rely on CentOS for key infrastructure. The unexpected EoL declaration meant that CentOS 8 would no longer get security upgrades, bug patches, or new features as planned. This put enterprises in a difficult situation, especially if they had already spent time and resources adopting CentOS 8.
- Compatibility with RHEL: CentOS is a popular free alternative to RHEL. With the transition to CentOS Stream, the compatibility between CentOS and RHEL became unclear. This modification sparked worries about potential compatibility difficulties, making it more difficult to ensure seamless transitions between development, testing, and production environments.
- Community trust and perception: The CentOS project had a solid reputation and was widely trusted by the open-source community. The abrupt transition to CentOS Stream, combined with the shortened support horizon for CentOS 8, resulted in a loss of trust and generated concerns about the project's future direction. The announcement caught many people and organizations off guard, causing annoyance, anxiety, and feelings of betrayal.
- Migration challenges: Despite the lack of official support, some users opted to continue with CentOS 8 and explore alternate community-supported solutions. Others switched to alternative Linux distributions, including Ubuntu, Debian, and even paying RHEL subscriptions. Migrating to a new operating system necessitates work, potential compatibility concerns, and reconfiguration of current systems, which can be time-consuming and expensive.
- Ecosystem impact: CentOS has a huge and thriving ecosystem of software packages, community-driven projects, and third-party technologies that support it. The EoL announcement upended this ecosystem, causing uncertainty for developers, system administrators, and users who rely on CentOS-specific tools and repositories.
CentOS 8 Stream: A False Hope?
The switch to CentOS 8 Stream has raised arguments and worries in the community, with some questioning if it is a feasible road ahead or a false hope. This transition from the conventional CentOS paradigm to a rolling-release variant closely connected with Red Hat Enterprise Linux (RHEL) development has prompted concerns about the platform's future stability, dependability, and long-term supportability. Users are wrestling with the implications of CentOS 8 Stream for their server infrastructure and want to know how it differs from previous CentOS releases.
Upstream vs Midstream
To understand the distinctions between upstream and midstream in the context of CentOS and CentOS Stream, let's define them:
- Upstream: In software development, "upstream" refers to the project's initial source. It is where the main development and decision-making occur. Upstream projects generate the underlying code, features, and updates that are then used in downstream projects.
- Midstream: The term "midstream" is not commonly used in software development. However, it might be understood as a transitional step between upstream and downstream processes. In the context of CentOS Stream, midstream refers to the CentOS Stream distribution that gets updates and changes from Red Hat Enterprise Linux (RHEL) upstream development before incorporating them into RHEL.
In the case of CentOS Stream, it serves as a link between RHEL's upstream development and CentOS's downstream releases. CentOS Stream receives updates and modifications before RHEL, giving consumers a preview of what to expect in future RHEL releases. This contrasts with the conventional CentOS paradigm, in which CentOS lagged behind RHEL and tried to provide a reliable and fixed version of RHEL.
Announcement & PR
The announcement and public relations efforts surrounding CentOS changes, such as the shortened support timeframe and the transition to CentOS Stream, sparked dissatisfaction and betrayal among users and organizations. The perceived lack of communication and collaboration compounded the negative response from the community, emphasizing the significance of community engagement. The CentOS project attempted to clarify and answer concerns, clarifying the rationale for the modifications and underlining the benefits of CentOS Stream. However, the first announcement and PR response had a huge impact on CentOS's perception and uptake, resulting in a loss of confidence that the project must rectify.
Official Clarification
The CentOS team responded to the community outrage by issuing official clarification via multiple communication channels. They clarified that CentOS Stream is an upstream development branch of RHEL that is closely connected with its development but does not serve as a drop-in replacement. They provided instructions on migrating from CentOS 8 to CentOS Stream and emphasized the need for increased community interaction. However, the impact of the clarification on restoring trust and support from dissatisfied users is unknown.
