With the support of the open-source community behind it and a strict privilege system embedded in its architecture, Linux has security built into its design. That being said, gone are the days that Linux system administrators could get away with subpar security practices. Cyber criminals have come to view Linux as a viable attack target due to its growing popularity, the valuable devices it powers worldwide, and an array of dangerous new Linux malware variants that have emerged in recent years.

Red Hat’s recent decision to discontinue CentOS 8 has left a critical void in the enterprise Linux market, shifting the spotlight onto other enterprise-ready Linux distributions. One distro that stands out as a viable CentOS 8 replacement among respected enterprise Linux distributions such as Ubuntu, Red Hat Enterprise Linux (RHEL), AlmaLinux and SUSE is Oracle Linux, an OS compiled from the same open-source code as RHEL.

Alternatives to CentOS Linux 8

In December 2021, CentOS support ended so the company could focus on CentOS Steam instead. Companies with long-term contracts with CentOS may have had issues converting to another program with such short notice, and if they could not grab one in time, their business faced network security issues, compliance risk, and minimal availability. Fortunately, CentOS 7 is still available until 2024. However, there was no way to upgrade CentOS 7 as a short-term solution for CentOS 8 in the interim.
