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

Developers and system administrators need better ways to deliver applications with increased speed and flexibility. Linux Containers, when used as an open source application packaging and delivery technology, meet this need by combining lightweight application isolation with the flexibility of an image-based deployment method. Red Hat has been working hard to make container technologies safer and easier to consume for the enterprise. Yesterday, at AWS re:Invent, we continued to make progress by offering attendees a chance to dive deep and develop skills for working with containers on AWS at a technical bootcamp.
This full-day, in-person training session provided a chance for developers and system administrators to learn first-hand from Red Hat knowledge experts and gain skills to deploy container-based applications with AWS. Content included instructor-led presentations and practical exercises, with several hands-on labs.
Through a series of labs

At Red Hat Forum in Singapore, Mark Coggin, senior director, product marketing, platform, Red Hat Inc., presented an overview of Red Hat Enterprise Linux 7 Atomic Host & Containers. Watch the video to see Mark as he talks about containers, how they deliver controlled runtime environments and portability with application environments. He also provides an overview of Red Hat Enterprise Linux Atomic Host, a lean operating system designed to run docker-formatted containers.
Because more and more enterprises are considering containerization as a new application deployment model, Red Hat hopes to make the adoption of container technology as smooth as possible for our customers. We are evaluating and testing various workloads in-house and spend a good chunk of our engineering time developing, integrating, and testing a trusted, supported application platform stack for containerized applications. The recent announcement of the Red Hat Enterprise Linux 6 platform image moves us even closer to the goal: we now have another certified platform that can run applications as complex as Oracle Database in a container (see video below).
Databases are among the most widely deployed applications out there and are often seen as the hardest to deploy. Containers promise to ease that pain

What if you could run your existing Red Hat Enterprise Linux 6 applications on Red Hat Enterprise Linux 7 without porting or making changes to your source code? Today, we are pleased to announce the immediate availability of the Red Hat Enterprise Linux 6 platform image, which allows for the creation of Red Hat Enterprise Linux 6-based application containers. Applications that have been developed, tested, and certified for Red Hat Enterprise Linux 6 systems can now be deployed as a container and run on Red Hat Enterprise Linux 7 as a container host.
This new platform image allows customers to

Applications, virtual machines, containers… what do they all have in common? They each operate on top of the solid foundation that is the operating system. In fact, in a world where the pace of technological change is unrelenting, where change is perhaps the only constant, there will always be a need for a reliable platform to build upon. Has the operating system become a modern day utility? Find out here.
The advent of any new technology tends to generate a lot of excitement. Over the course of my career, however, I have never experienced “a buzz” like what we are seeing around Linux containers and application packaging and isolation, containerized applications built in the Docker format. From my perspective, the ways in which containers may influence our ever evolving technological ecosystem are, quite possibly, limitless…okay, limitless may be strong, and while “game changing technology” may sound cliche, it’s not far from the truth in this case.

It’s difficult to overestimate the importance of networking in today’s business environment. Since networking provides a central means for data exchange and collaboration, it is often a critical factor when it comes to determining an organization’s ultimate potential for success.
At Red Hat, we understand the importance of networking and the role it plays in maintaining business continuity. As such, we made networking one of the primary focus areas of development for Red Hat Enterprise Linux 7. Having incorporated numerous enhancements and performance optimizations into the Red Hat Enterprise Linux 7 beta – I’d like to take this opportunity to talk about “what’s new” with respect to improvements in network management, bandwidth, and security.
