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

Several weeks ago Red Hat and Cisco collaborated on a whitepaper for IT leaders and industry analysts on Linux containers. The following is an excerpt from the first page:
“Linux containers and Docker are poised to radically change the way applications are built, shipped, deployed, and instantiated. They accelerate application delivery by making it easy to package applications along with their dependencies. As a result, the same containerized application can operate in different development, test, and production environments. The platform can be a physical server, virtual server, public cloud, or network device.”

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.
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.
