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

Closing the Integration Gap

This post is the second in a series of blog posts about integrating Linux systems into Active Directory environments. In the previous post we discussed dishwashers and, more seriously, some basic principles. In this post I will continue by exploring how the integration gap between Linux systems and Active Directory emerged, how it was formerly addressed, and what options are available now.

Let’s start with a bit of history… before the advent of Active Directory, Linux and UNIX systems had developed ways to connect to, and interact with, a central LDAP server for identity look-up and authentication purposes. These connections were basic, but as the environments were not overly complex (in comparison to modern equivalents) – they were good enough for the time. Then… AD was born.

Active Directory not only integrated several services (namely: LDAP, Kerberos, and DNS) under one hood, but it also

Mysteries of NUMA Memory Management Revealed

The memory subsystem is one of the most critical components of modern server systems–it supplies critical run-time data and instructions to applications and to the operating system. Red Hat Enterprise Linux provides a number of tools for managing memory. This post illustrates how you can use these tools to boost the performance of systems with NUMA topologies.

How Red Hat Enterprise Linux Atomic Host Powers OpenShift Online

The OpenShift Online Technical Operations team was looking forward to the beta availability of Red Hat Enterprise Linux Atomic Host. In fact, they participated in early sprints as part of the Atomic Special Interest Group (SIG) to help make sure Red Hat Enterprise Linux Atomic Host had the operational “beef” to stand high alongside Red Hat’s other enterprise products. Part of this process led to us running the unreleased bits in OpenShift Online prior to the beta announcement.

That said, we’re not using it to run some corner niche of our infrastructure. Instead, we are using the Red Hat Enterprise Linux Atomic Host + Docker combo to run our reverse proxy tier. This means that every API, www.openshift.com, and web console request made to OpenShift Online runs through this tier.

So why all the interest? The small size of Red Hat Enterprise Linux Atomic Host is the

Red Hat Enterprise Linux 7 Atomic Host Beta: Tell Us What You Think

beta-feeback

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?

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

AWS re:Invent Bootcamp Attendees Learn How to Accelerate Development with Linux Containers

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

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
