Top 3 Reasons to Run Container-Based Applications on Red Hat Enterprise Linux 7

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

Red Hat Enterprise Linux: Powering the World’s First Big Data Benchmark Results with Cisco

Red Hat and Cisco have a long history of offering joint solutions that benefit our mutual customers and address a gamut of IT challenges, from server sprawl to cloud computing. Both companies consistently foster technological innovation and work towards breaking new ground in computing, including a history of driving world-record performance across a wide range of industry-standard benchmarks.

Industry standard performance benchmarking, driven by groups like TPC and SPEC, goes all the way back to 1988. Many of these benchmarks have driven the development of faster, cheaper, and more efficient computer technologies over the course of the past quarter century.

With over a hundred of benchmark records to its name, Red Hat Enterprise Linux is known to power some of the most

Performance Testing Red Hat Enterprise Linux 7 Atomic Host Beta on Amazon EC2

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

Containerizing Databases with Red Hat Enterprise Linux

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

Containerize Red Hat Enterprise Linux 6 Applications to Run on Red Hat Enterprise Linux 7

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.

Red Hat Enterprise Linux: The Leading Platform for Top-Tier Performance

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

The Application Apartment Complex: Red Hat Enterprise Linux & Linux Containers

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.

KVM Virtualization: Refining the Virtual World with Red Hat Enterprise Linux 7 Beta

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.

Is there a best Linux file system?

Is there a best anything? Perhaps. I, personally, tend to think that home-made chocolate chip cookies are the best dessert. However, when it comes to file systems… there are no absolutes.

File systems come in all shapes and sizes; and where one may be perfect for a particular application or scenario – it may not be right for other use cases. This is where Red Hat Enterprise Linux 7 beta shines as it brings a variety of substantial enhancements to file systems in the form of scalability improvements, performance enhancements, and file system choices.
