Red Hat OpenShift

Andrew Block of Red Hat will be speaking on this topic at DevOps Enterprise on 21 October - below is a primer from him on what he'll cover: Although the DevOps movement clearly and correctly centers around culture and the processes that guide or derail our success, the root of this shift often gets overlooked in favor of the symptoms. Sure, we all want our teams better aligned and more consistent, our processes streamlined and automated, our release cycles as...

If you'd like to receive this monthly newsletter with fresh news, register here . Red Hat Developers Newsletter - August 2015 Welcome to the Red Hat ® Developers Newsletter. This month, many of you are getting your kids ready to go back to school. Learning can be a lot of fun, and we Red Hatters wish them (and you) good luck for the new year. By the way, have you learned something new lately? How about containers or Red Hat...

This is a guest post written by Red Hat's own Gunnar Hellekson. I tend to pay attention to what Gunnar has to say and recommend the same. "There are three big challenges that lay between containers-as-toy and containers-as-infrastructure: Containers demand a lot more automation than you have now. Containers make you an operating system vendor. Containers drive organizational changes." Source: Red Hat: Containers for Grown-Ups - Tools Advisor

A number of Red Hatters are attending this week's NodeConf.eu as one of the event sponsors, but we're also here to learn more about Node.js and listen to some great sessions. Plus, I've met probably a dozen Red Hatters for the first time - most of whom are part of the Red Hat Mobile Application Platform team (formerly FeedHenry). Another nice benefit for this event is that it's in Waterford, Ireland, and specifically at Waterford Castle (TRULY - this is...

From the buzz on Twitter and blog posts, you could feel that ECMAScript 6 was finally coming. It has many things we’ve wanted for years, so it makes sense to start new projects with it in mind. ECMAScript 6 Others have written in depth about various ECMAScript 6 features . I’d like to focus just on one: module loading. There is no common way to load your ES6 modules natively in the browsers. For example babel , has support for...

At DevNation 2015 , Jason Hibbets shared a behind the scenes look at opensource.com , the talent behind it, their content strategy, and the results of the overall success of the site. Why I liked it? It was great to hear more about the inner workings of the opensource.com team. Most importantly, I found it very informative with specific info on how to get involved in the community that participates in the site. Read more about it – they are...

So Docker containers are all the rage, right? (If you didn't know this, you do now.) :) For a while now, Red Hatters have already been doing a ton of upstream container work on Docker, Kubernetes , and a new item called Nulecule . But while Docker containers have skyrocketed in popularity, there's been no convenient means to set up a development environment for building containerized apps. Wouldn’t it be handy to develop YOUR containerized apps for Red Hat Enterprise...

As part of our participation in hundreds of open source communities, Red Hat engineers are often involved in research and development efforts that may or may not become a part of Red Hat's supported offerings. Intel's Data-plane Development Kit (DPDK) is a set of libraries and drivers for Linux and BSD built for fast packet processing, for the burgeoning " Network Function Virtualization ", or NFV discipline. Typical verticals interested in turning Linux boxes into packet-processing machines are telecom, financial...

by Chris Aniszczyk, Head of Open Source, Twitter Apache Mesos is a resource manager for datacenter infrastructure that uses a 2-level scheduling model to provide hardware resources to various application frameworks.Similar to Infrastructure-as-a-Service (IaaS), Mesos manages hardware and the execution of applications, while delegating the responsibility of deployment to other platforms. In the Mesos’ model, application frameworks are responsible for scheduling and deployment logic. Multiple frameworks can be run on bare metal at the same time, using a single pool...

Red Hat's Arun Gupta, the Java guru, has this great talk at DevNation: Techniques such as automated builds and testing, continuous integration and continuous deployment allow software to be developed to a high standard and easily packaged and deployed to test environments, resulting in the ability to rapidly, reliably and repeatedly push out enhancements and bug fixes to customers at low risk and with minimal manual overhead. What container-agnostic tools are available for testing, continuous integration and deployment of a...

The Winter of Code is a challenge for the best application built on OpenShift .

From most practical to the most crazy, submit your applications and win fabulous prizes, such as Google Nexus Tablet and much more! The winners on each category will be announce...

In many organizations development teams are split up from systems administrators. Both teams focus mainly on their roles and responsibilities, but this can lead to problems. Tensions between the groups can hinder your organization's efforts in getting the best product to the consumers in the shortest amount of time. Below are quotes which are commonly come up between developers and systems administrators. “Why doesn't the development team have to be on call? It's their code that breaks the system.” “Why...

Containerizing things is particularly popular these days. Today we'll talk about the idioms we can use for containerization, and specifically play with apache spark and cassandra in our use case for creating easily deployed, immutable microservices. Note: This post is done using centos7 as a base for the containers, but these same recipes will apply with RHEL and Fedora base images. There are a few different ways to build a container. For example, for beginners, you can build a container...

This is a short heads-up about an upcoming, free webinar which discusses the influence of the growing demands for hyper-connected, internet-driven economy where users expect speedy delivery of new features, highly engaging personalized user experiences, and smooth, streamlined performance on today's application architecture and design. The result is that best practices for application development and architecture are rapidly changing. Traditional approaches to development are no longer competitive, with the new focus on simplicity, usability, and large-scale DevOps agility. In order...

Il y a quelques mois, j'ai développé et publié une petite extension Puppet pour tuned-adm . En effet, cette commande est une fonctionnalité assez appréciable de RHEL , et il m'a semblé donc pertinent d'évoquer cette dernière sur Red Hat developer blog . Tour d'horizon de 'tuned-adm' Pour faire court, cette commande va s'occuper des nombreux fins réglages du système d'exploitation pour vous, selon l'usage que vous souhaitez faire de ce dernier. Par exemple, si vous utilisez le système comme...

Can you believe it's December and almost 2015? Where does the time go? Last month, we shared a Thanksgiving "thank you" for open source. December holidays are commonly about giving, so Red Hat is giving you the opportunity to use containers with the new availability of Red Hat Enterprise Linux® Atomic Beta. This follows the Red Hat Summit 2014 announcement about application containers, including the upstream Project Atomic and our intent to develop a small footprint, container host based on...

In the United States, we celebrate Thanksgiving on the fourth Thursday of November, which follows our Canadian colleagues who celebrate theirs in October. It's a day for families to get together and give thanks for what we have. Our Red Hat family wants to give thanks for open source, too. Can you imagine an IT world without open source? A number of UNIX businesses would be different. Same with development tools. We have so many scripting languages and other developer...

Here are some quick references to see and learn from the recent DevOps Enterprise Summit hosted by Electric Cloud and Gene Kim's IT Revolution . First, a summary from the former. "What a great week we had at the DevOps Enterprise Summit! "The conference was completely sold out, and it was standing room only most of the time. We had many excellent examples of enterprises applying DevOps practices in the real-world, from the likes of Disney, GE and Nordstrom –...

Like most programmers, I find it much easier to take some existing example of code and modify it to do what I want. Sometimes, I end up with nothing from the original source, but I still find it easier. I wonder if this is akin to writing where, I find, if you put the words down in a stream of consciousness manner, then " rewrite , rewrite , rewrite ." As such, I am really excited about the efforts from...

Traveling to San Francisco for the DevOps Enterprise conference has been a transformational event for me. Even though I had been aware of the success stories of companies like Target, Disney, Raytheon, it was quite a different matter to experience their stories in person. The most critical lesson from day one for me was to focus on the community to help you remain positive, motivated, educated and most importantly accelerate the adoption of the DevOps movement in your organization. Critical...
