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?

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

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

Since its introduction more than a decade ago, Red Hat Enterprise Linux has become the world’s leading enterprise Linux platform. Along the way it has set the industry standard for performance as most recently demonstrated by Red Hat Enterprise Linux 7 delivering multiple world record-breaking benchmark results at launch. These results showcased close collaboration between Red Hat and our ecosystem of partners.
With history as a backdrop, it should come as no surprise that many of our partners rely on Red Hat Enterprise Linux to support their ongoing benchmarking efforts. Red Hat and Intel have enjoyed a long history of collaboration across a full spectrum of all that is enterprise IT – covering everything from applications running on physical servers to virtualized and cloud-based deployments. In fact, during yesterday’s launch of the Intel Xeon E5-2600 v3 processor family

In the second installment of “what’s new” for networking features in Red Hat Enterprise Linux 7, I’d like to shift the focus and spend some time talking about improvements to network time synchronization and enhancements in the network stack designed to reduce latency. Note that the previous installment of this two part series was posted during the Red Hat Enterprise Linux 7 beta; now that Red Hat Enterprise Linux 7 is generally available I encourage customers to visit the Red Hat Customer Portal, download this latest release, and to let me know what you think.
Highly Accurate Time Synchronization
Precise time synchronization with microsecond or nanosecond accuracy is increasingly critical to the success of many high-speed, low-latency applications. Whether tracking time on trading transactions or market feeds, improving the time stamp accuracy on archived data, or administration-free time synchronization of servers within a rack (or around the world) for automation or regulatory purposes, precision time synchronization is a key enabler for delivering better performance.
New to Red Hat Enterprise Linux 7,

Were you able to attend the Red Hat Enterprise Linux roadmap session at this year’s Red Hat Summit? If not, I have some good news – the slides are still available (here). In addition, many of the questions that were asked after the presentation were recorded, sorted, and answered… and are now posted on the Red Hat Summit Blog. Of note:

In this day and age, where almost everything is connected to the World Wide Web, the demands on networking (in general) are mushrooming. In the developed world it’s common to be able to get 20 megabits per second connections on our mobile devices and 50 megabits per second connections at home. By extension, the demands on enterprise data centers are even higher (by at least three to four orders of magnitude) – as these central “hubs” are where traffic from the aforementioned individual end nodes converge. Consider the act of flipping through a series of cloud-hosted HD photos on a mobile device – this can easily result in billions of packets being transferred (in fractions of a second).
The good news is that our networking interfaces are getting “bigger and faster.” 40 gigabit per second Ethernet is currently being deployed, and work to finalize on 100 gigbit per second end point interfaces is currently underway.
