Earlier in March we announced the general availability of Red Hat Enterprise Linux 7 Atomic Host, 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. In my previous container blog I gave the top seven reasons to deploy Red Hat Enterprise Linux 7 Atomic Host. One reason was the ability to do atomic updates and rollbacks. In this blog I provide an in-depth look into atomic updating and how it differs from a yum update. And, speaking of atomic updates

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?

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.
What are the top 7 reasons to deploy containers on Red Hat Enterprise Linux 7 Atomic Host?

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

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.

Someone out there “gets” the title, right? No, I’m not suggesting that Red Hat Enterprise Linux 7 Beta is an interactive puzzle adventure game. The relationship, I suppose, is in fact based on a much looser association: this is our seventh major release and this post (as opposed to my first) is dedicated to Red Hat Enterprise Linux running as a guest on third party hypervisors.

Ever since Red Hat Enterprise Linux added KVM Virtualization as a kernel-based hypervisor to run virtual machines (way back in Red Hat Enterprise Linux 5.4), the operating system took on a dual personality.
Red Hat Enterprise Linux became both a Virtualization host for high density virtual data centers / cloud service platforms, and a guest operating system running on third party hypervisors such as VMware vSphere and Microsoft Hyper-V. As the topic is sufficiently broad, I plan to split my discussion of virtualization into two posts.
Today’s post will discuss Red Hat Enterprise Linux 7 beta as a hypervisor using KVM Virtualization technology and it will highlight a few key enhancements that make Red Hat Enterprise Linux the operating system of choice for modern hybrid data centers. While the features that I will review are inherently those that I find to be the most exciting (note: I’m hoping you will find them to be exciting and useful as well), a complete list is available in the Red Hat Enterprise Linux 7 beta release notes.
