Red Hat Enterprise Linux 7 Atomic Host Beta is an operating platform that is optimized and minimized to run containers. It packages key components of Red Hat Enterprise Linux 7 such as SELinux, systemd, and tuned with the kernel to facilitate running containers in a secure and optimized manner. It also offers Kubernetes and Docker to facilitate the rapid creation, deployment, and orchestration of containers – simplifying the life cycle management of applications and systems.
Containers allow users to put application and all of their runtime dependencies into secure packages that are both easy to deploy and easy to manage. Containers are also portable and images of a given container can be copied and replicated to other systems. Since containers are isolated from each other and are isolated from the host OS, libraries and application binaries can be updated individually without affecting other containers or the host OS (and vice versa).
