By CIOReview | Monday, March 9, 2015

RALEIGH, N.C.: Red Hat, a provider of open source solutions, has announced the availability of Red Hat Enterprise Linux 7 Atomic Host (RHELAH), which is a purpose-built container host for secure and reliable containerized applications across the open-hybrid cloud.

Steven J. Vaughan-Nichols, for ZDNet opines that this atomic host is the ideal way to leverage and combine enterprise Linux and Red Hat Enterprise Linux, with Docker. It provides the components required to package and run applications written for Red Hat Enterprise Linux 6 and 7 as containers and allows enterprises to adopt a container based architecture, without compromising on stability and security.

RHELAH enables the user to download and deploy atomic update in a single step, while retaining the previous version. The other key feature of the atomic host is that it allows container images in Docker format to be deployed and run as application containers. Security-Enhanced Linux (SELinux), cgroups and kernel namespaces, isolate containers individually in a multi-container environment and thereby provide enhanced security.

Further certification and support comes with, a chain of trust for containers built using platform images provided by Red Hat Enterprise Linux 6 and 7 and certified containers from Red Hat’s independent software vendor (ISV) partners. Also, the specialized containers facilitate the installation of third party software, and the Linux 7 atomic host simplifies the running of super privileged containers.

RHELAH makes effective use of Red Hat’s certified ecosystem and enables secure and stable container deployments on physical hardware and certified hypervisors like Red Hat Enterprise Virtualization, VMware and Microsoft Hyper-V, as well as public cloud services like Amazon Web Services and Google Cloud Platform.

“More than just an addition to the Red Hat Enterprise Linux portfolio, Red Hat Enterprise Linux 7 Atomic Host showcases the future of the enterprise application, a powerful, flexible application greater than the sum of its parts, and entirely fueled by the power of open innovation,” says Jim Totton, Vice President and General Manager, Platforms Business Unit, Red Hat.
