1. Rocky Linux 8

Rocky Linux is a community enterprise operating system designed to be 100% bug-for-bug compatible with America’s top enterprise Linux distribution now that its downstream partner has shifted direction. It is under intensive development by the community. Rocky Linux is led by Gregory Kurtzer, founder of the CentOS project after RedHat decided to switch to CentOS Stream. CentOS Stream tracks just ahead of a current RHEL release. CentOS will no longer be a stable point distribution but a rolling release Linux distribution.

Rocky Linux 8 is a downstream rebuild of RHEL 8 and, as such, aligns with the RHEL 8 lifecycle and therefore will be actively maintained until 2029. As of early August 2021, Rocky Linux has almost 100 mirrors, including a global CDN (Content Delivery Network). Over 80 mirrors provide HTTP, over 80 mirrors provide HTTPS and over 50 provide RSYNC connections.

So far, Rocky Linux has gained immense adoption and support from the community and its future is amazingly bright. It performs well as a server since it is based on RHEL’s stable source code hence can be used to power your production workloads without any fuss or doubt.

• A good replacement for CentOS 8
• Backed by community support that is growing and vibrant
• You get latest release of software
• A vibrant and growing community that is eager to make amends after CentOS switch.

• It is still young compared to other stable distributions.

2. CentOS Stream 8

Late last year (2020) RedHat announced that it was changing how CentOS was going to be going forward. It was shocking news that they were shifting focus from CentOS Linux, a distribution priding itself in stability as a rebuild of Red Hat Enterprise Linux (RHEL), to a rolling release Linux CentOS Stream distribution. This means that CentOS Stream will be tracking just ahead of a current RHEL release positioned as a midstream between Fedora and RHEL. To bring the point closer home, CentOS is no longer a stable point distribution but a rolling release Linux distribution now known as CentOS Stream 8. As for CentOS 8, Red Hat will take the mantle of updating it until the end of 2021 to the dismay of many CentOS users who had settled for the earlier promise that it was going to receive updates till 2029.

A rolling-release Linux is one that is constantly being updated hence having the major issue of powering your production workloads. This is because something may break in the rolling release to the detriment of your applications. Use it in production knowing that bugs may appear anytime.

• You get the backing of RedHat
• You get latest release of software

• Stability and dependability get sacrificed on the altar of bleeding edge.
• With a rolling release, major bugs might appear in a production system.

3. RHEL 8

RedHat Enterprise Linux as the name suggests is a Linux distribution developed by RedHat, the company, and delivered to customers via a Licensing model.
