The Fedora distribution maintains several editions and one of the lesser talked about editions is Atomic Host. The Atomic Host edition is a lightweight platform for running containers. Due to Atomic Host's minimal and fast-moving nature, the Fedora team is changing the edition's life cycle to be different from the life cycles of Fedora's Workstation and Server editions. A post on Fedora Magazine explains: "The Fedora Atomic Working Group will then collapse Fedora Atomic into a single version. That release will track the latest stable Fedora branch. When a new stable version of Fedora is released, Fedora Atomic users will automatically shift to the new version when they install updates. Traditional OS upgrades can be disruptive and error-prone. Due to the image-based technologies that Atomic Hosts use for system components (rpm-ostree) and for applications (Linux containers), upgrading an Atomic Host between major releases is like installing updates within a single release. In both scenarios, the system updates are applied by running an rpm-ostree command and rebooting. The release provides rollback to the previous state available in case something goes wrong. Applications running in containers are unaffected by the host upgrade or update."
