Red Hat Enterprise Linux Atomic Host
By combining the flexible, modular capabilities of Linux containers with the reliability and security of Red Hat Enterprise Linux, customers can securely and efficiently deploy and update containers across traditional and public, private, and hybrid cloud infrastructures. Explore the technical specifications, features, and benefits of containerization with Red Hat.
Red Hat Enterprise Linux Atomic host is a variation of Red Hat Enterprise Linux 7 optimized to run Linux containers in the Docker format. It has been designed to take advantage of the powerful technology available in Red Hat Enterprise Linux 7. Red Hat Enterprise Linux Atomic Host uses SELinux to provide strong safeguards in multi-tenant environments, and provides the ability to perform atomic upgrades and rollbacks, enabling quicker and easier maintenance with less downtime. Red Hat Enterprise Linux Atomic Host uses the same upstream projects delivered via the same RPM packaging as Red Hat Enterprise Linux 7.
Red Hat Enterprise Linux Atomic Host File System
Red Hat Enterprise Linux Atomic Host uses rpm-OSTree (also called atomic), an open source tool, to manage bootable, immutable, versioned file system trees made of RPM content. These trees are currently composed by Red Hat, from packages. The rpm-ostree tool replicates the trees atomically. This results in a strategy for upgrade and maintenance that centers around atomic updates. The use of rpm-ostree instead of yum to upgrade and maintain software means that Red Hat Enterprise Linux Atomic Host is managed differently than other Red Hat Enterprise Linux 7 variants.
Red Hat Enterprise Linux 7 Atomic Host provides many benefits, including:
