List of Top 5 CentOS Linux Alternatives 2021

Red Hat recently announced that CentOS Linux is to be terminated and all the focus and energy will be shifted towards the development of CentOS Stream. While ecosystem developers are happy with the announcement as CentOS Stream is mainly a platform for upstream development, CentOS Linux users have already searching for a viable alternative to CentOS.

In this article, we will discover and analyze the various CentOS Linux alternatives and their features.

1) Rocky Linux

If you are looking for the best CentOS alternative, Rocky Linux grabs the first place in the list of alternatives. One of the many reasons that Rocky Linux tops the list is because it is developed by a team headed by none other than Gregory Kurtzer, one of the co-founders of CentOS. This alternative is named to honor its other co-founder late Rocky McGaugh.

Rocky-Linux-Distro

Rocky Linux is specially developed as a community enterprise OS compatible with RHEL. It is also said that there are plans for a community-based replacement for CentOS Linux. A few days before, Rocky Enterprise Software Federation (RESF) announced the release of Rocky Linux 8.4.

With the release of Rocky Linux 8.4, users can easily run apps built for RHEL without having RHEL. But even though Rocky Linux 8.4 is touted to be a production ready distribution, one of the main features is still missing. Yes, Secure Boot feature is not available with 8.4, but the team says that a Secure Boot support will be released soon.
