Over the last 18 months, especially since the general availability of Red Hat Enterprise Linux 7, “containers” have emerged as a hot topic. With the more recent introduction of Red Hat Enterprise Linux Atomic Host, an operating system optimized for running the next generation of applications with Linux containers, one might wonder… what about virtualization? In that the benefits of containerization seem to overlap those of traditional virtualization, how do organizations know when to pick one approach over the other?

Today marks an exciting milestone for Red Hat as we share news of the general availability of Red Hat Enterprise Linux 7 Atomic Host, an operating system optimized for running the next generation of applications with Linux containers.
Based on the world’s leading enterprise Linux platform, Red Hat Enterprise Linux Atomic Host enables enterprises to embrace a container-based architecture to take advantage of the benefits of development and deployment flexibility and simplified maintenance, without sacrificing performance, stability, security, or the value of Red Hat’s vast certified ecosystem.
An application architecture based on Linux containers requires not only the tools to build and run containers, but also an underlying foundation that is secure, reliable, enterprise-grade, with an established lifecycle designed to meet the ongoing requirements of the enterprise over the long term. The release of Red Hat Enterprise Linux Atomic Host supports Red Hat’s commitment to make Linux containers a stable and reliable component of enterprise IT across the open hybrid cloud.
Red Hat Enterprise Linux 7 Atomic Host provides many benefits, including

As product manager for Red Hat Enterprise Linux 7, part of my job is to ensure that the latest version of our flagship product adheres to our promise of stability, reliability, and security. In addition, as Red Hat Enterprise Linux 7 is Red Hat’s latest enterprise Linux platform, it also needs to incorporate new innovations in technology to help our customers gain business advantage, reduce costs, and increase efficiency without compromising their existing investments. With this in mind, the Red Hat Enterprise Linux team takes great care in evaluating new technology to ensure that it is introduced in a manner that is minimally intrusive (if at all) and is a natural fit for the platform. Support for Linux containers and the ability to host container-based applications are great examples of this and Red Hat Enterprise Linux 7 stands ready for the challenge.
Creating and operating application containers via process isolation is not a new concept. Red Hat Enterprise Linux 6 sowed the seeds for this way back in 2010 with the introduction of Control Groups (cgroups). Since that time there have been many exciting developments in this area with active participation from Red Hat. Building upon cgroups functionality, enhancements to the kernel combined with an easy-to-use container format (Docker) make now an opportune time to consider deploying container-based applications on Red Hat Enterprise Linux 7.
Here are the top three reasons to consider Red Hat Enterprise Linux 7 as the host for your container-based applications

The OpenShift Online Technical Operations team was looking forward to the beta availability of Red Hat Enterprise Linux Atomic Host. In fact, they participated in early sprints as part of the Atomic Special Interest Group (SIG) to help make sure Red Hat Enterprise Linux Atomic Host had the operational “beef” to stand high alongside Red Hat’s other enterprise products. Part of this process led to us running the unreleased bits in OpenShift Online prior to the beta announcement.
That said, we’re not using it to run some corner niche of our infrastructure. Instead, we are using the Red Hat Enterprise Linux Atomic Host + Docker combo to run our reverse proxy tier. This means that every API, www.openshift.com, and web console request made to OpenShift Online runs through this tier.
So why all the interest? The small size of Red Hat Enterprise Linux Atomic Host is the

In November we announced Red Hat Enterprise Linux 7 Atomic Host Public Beta, a small footprint, container host based on Red Hat Enterprise Linux 7. It provides a stable host platform, optimized for running application containers, and brings a number of application software packaging and deployment benefits to customers.

Applications don’t always work as expected, and “it works fine on my machine” — the first line of response when reporting an issue — has been around for decades. One way to avoid the challenge of application issues in production is to maintain identical environments for development, testing, and production. Another is to create a Continuous Integration environment, where code is compiled and deployed to test machines and vetted with each and every code check-in, long before being pushed to production.

It’s been one week since we announced the beta for Red Hat Enterprise Linux 7 Atomic Host and we’re looking for your feedback. If you’ve downloaded and installed the beta, this is your chance to tell us what you think, and what you’d like to see in the product moving forward.
TechValidate is conducting a short, 5-minute survey on behalf of Red Hat. Why should you participate?

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).
The following video (below) mirrors the demo as presented
