Red Hat Releases Project Atomic
In April, Red Hat released Project Atomic, a prototype system for running Docker containers. This is Red Hat’s response to the interest in CoreOS a system for hosting Docker containers based on ChromeOS.
Project Atomic is not intended to be another operating system; Red Hat already has RHEL, Fedora and now CentOS, so a fourth OS would not make much sense. Instead it is currently a prototype using Fedora, with a CentOS version slated to come soon, not yet a production product.
