5 Reasons Why AlmaLinux Outperforms CentOS as an Alternative

AlmaLinux is a free and open-source Linux distribution that serves as a reliable replacement for CentOS, addressing its limitations and providing a stable and compatible alternative for businesses and individual users. Developed and maintained by an active community, AlmaLinux offers a platform where creativity can thrive, supported by the slogan "for the community, by the community." Since its initial release in 2021, AlmaLinux has gained popularity and achieved a dedicated user base.

CentOS, short for Community Enterprise Operating System, has long been a popular free Linux distribution, offering an advanced alternative to Red Hat Enterprise Linux (RHEL) without the obligation of support fees. However, CentOS 7 users received disappointing news that the operating system would be discontinued by the end of 2024, leaving them with less than a year to find an alternative.

CentOS Stream emerged as the successor, primarily serving as a platform for software testing and development. However, many users expressed concerns about its stability and bugs compared to the original CentOS Linux. Another option, CentOS EoL, also fell short as a replacement.

Thankfully, the creator of CentOS, Gregory Kurtzer, foresaw this situation and had a plan to make sure that CentOS fans would be satisfied if it ever reached the end of its existence.
