CentOS EOL: Transitioning to CentOS Stream and Alternatives

Latest update: June 10th, 2024.

With CentOS 8 reaching its End of Life (EOL), it's crucial for users to consider their next steps. Here’s an in-depth look at CentOS Stream and some viable alternatives:

Why is CentOS 8 EOL?

CentOS 8 has reached its End of Life due to a strategic shift by Red Hat, announced in December 2020. The decision to transition from traditional CentOS to CentOS Stream reflects Red Hat's aim to foster closer integration between RHEL development and community feedback. This change accelerates innovation by providing users earlier access to updates and features destined for RHEL.

What is CentOS Stream?

CentOS Stream is a rolling-release distribution that operates upstream of Red Hat Enterprise Linux (RHEL). Unlike traditional CentOS, which offered static point releases, CentOS Stream delivers a continuous flow of updates. This enables users to test and experience new features before they are included in RHEL’s official releases. However, this dynamic nature makes CentOS Stream less stable than traditional CentOS, as it functions as a development branch.
