Last week Red Hat announced the general availability Red Hat Enterprise Linux 7 Atomic Host, its container-optimized version of RHEL 7 based on Project Atomic, which comes with Docker pre-installed and a minimal footprint.
Despite containers are rarely seen in enterprise production environments (if we exclude Google where nearly-everything is non-standard) and most of the developers use them as a lighter version of VMs, Red Hat is investing significantly in this technology, supporting both classic LXC containers and Docker.
Red Hat OpenShift was the first solution to use containers as its foundation and now, with Atomic, Red Hat is going to pervasively support this technology across its entire Open Hybrid Cloud Stack.
