I returned late Sunday night from a trip to the south of France, where I was privileged to speak about Microservices, OpenShift, and how to do it all on Node.js. The conference was RivieraDev/JUDCon: Riviera 2017 and took place in Sophia Antipolis, near Nice, Cannes, St. Tropez and other fabulous Mediterranean cities on the southeastern coast of France. This was a two-day conference, sponsored in part by Red Hat. It was great to see so many Red Hatters there and...

Mandus Momberg, AWS Partner Solutions Architect, presented mechanisms to integrate OpenShift with AWS native features. Many of these concepts are covered in the Red Hat reference architecture for deploying OpenShift Container Platform 3.5 on AWS. To begin with, if you are running or considering RHEL on AWS, check out the Cloud Access Program. This allows you to convert standard RHEL subscription to cloud access licensing at a ratio of 1:2, 2 cloud VMs for every standard license. A lot of...

Rafael Benevides, Director of Developer Experience, at Red Hat spoke on rapidly deploying software on OpenShift with zero downtime. Throwing software over to an operations team to deploy during a scheduled maintenance window is a thing of the past. Businesses simply can no longer afford scheduled downtime. Applications need to be developed such that small, frequent updates can be released continuously via containers. Rafael shows us how to solve this problem with OpenShift. Blue/Green Deployments This is a released strategy...

Recently, the focus on the continuous delivery of value has created a lot of interest in microservices, CI/CD, and containers. The idea is that microservices are small and well defined enough to enable rapid innovation, automated testing, and frequent deployments with minimal risk. This is made possible by adopting continuous integration and continuous delivery pipelines. CI/CD requires the ability to quickly, easily, reliably, and automatically create and tear down complete execution environments. Linux containers address this need by creating lightweight...

Part II of the OpenShift.io Developer Tools overview follows on the heels of the introduction session, this time presented by Pete Muir and Gorkem Ercan. In this session, we are taken through the integrated OpenShift.io Eclipse Che IDE. What is a Cloud Workspace? One of the fundamental problems with today's development methodology is that development happens on your laptop-- in a completely different environment from production. This is one of the major sources of bugs as your software is migrated...

Yesterday, at Red Hat Summit, Red Hat announced OpenShift.io. OpenShift.io is the next generation OpenShift platform, based on OpenShift 3, for building and running applications in the cloud. It gives you complete control of your application's lifecycle, from build to production-- regardless of deploying from source or running a pre-built container. In the Developer tools, Overview and Roadmap Part I summit session, Todd Mancini, Peter Muir, and James Strachan take a packed house through an introduction to OpenShift.io (in addition...

Today's announcement of Red Hat OpenShift.io was followed by a full day of developer toolset Summit sessions. These were presented by the OpenShift.io product development team and covered some truly amazing OpenShift.io features. While there are too many features to cover in a single blog post, these were my top 7 items. 1. A Kanban board that is actually useful OpenShift.io is built from the ground up for development teams to rapidly release software. This is one of the primary...

Developers often ask themselves these questions: Is this the right dependency to add for the feature that I need to build? What open source libraries and/or packages are others using? Is this a stable and secure version? Does this package's license conform to my organization's policies? These are important questions that developers need to answer when choosing open source software components for their project. It is nearly impossible to deliver a modern application without depending on a number of software...

Installing software is a drag Getting a team set up to work on a new software project can be quite time consuming. You have some great ideas for the code you want to write, but you can’t get down to writing it until you have a development environment for yourself and the rest of the team. First, you have to select, download, and install tools. There are usually some settings that need to be configured for each one. Then, every...

Digital transformation is about evolving into a technology business to compete in the digital economy. Businesses can’t transform without relying on the developer to implement the transformation strategy and deliver value. Unfortunately, as developers look to adopt new approaches that let them deliver business value more quickly, they find it challenging to get started in a timely fashion. First, they have to pick a software stack to use as a foundation. In the world of open source, there is an...

Object-Oriented Primitives (in-process primitives) As a Java developer, I'm well familiar with object-oriented concepts such as class, object, inheritance, encapsulation, polymorphism, etc. In addition to the object-oriented concepts, I'm also well familiar with the Java runtime, what features it provides, how it manages my applications, what would be the life cycle of my object and the application as a whole, etc. And for over a decade, I've used all the primary tools, primitives, and building blocks as a developer to...

It’s hard to believe that spring of 2017 is upon us, and with it, the preparation for our second DevNation Federal. Last year has seen a surge of innovation in open source communities, and now more than ever it’s imperative that government agencies equip themselves for the change that lies ahead. This year, digital transformation , microservices , containers and Kubernetes are hotter than ever. Function as a Service (FaaS) , hyper-converged, and serverless architecture are on the horizon, and...

Hi there! It's been a while since I last wrote an article. Today, I want to show you how to easily setup some persistent storage for your projects in minishift / CDK 3 (Red Hat's Containers Development Kit 3). Prerequisites First, let's start planning what you'll need: A working minishift or CDK 3. That's all, I swear! I won't go deep into how to set up a minishift or CDK 3, there are many articles on the Internet to cover...

While validating OpenShift Container Platform on a VMware platform the usage of Atomic OS was also a requirement. In the initial reference architecture, the decision was made to use Red Hat Enterprise Linux as the platform. This platform was then customized and the same packages as in Atomic were installed via Ansible and Red Hat Network. The github repo with those playbooks is here: https://github.com/openshift/openshift-ansible-contrib/tree/master/reference-architecture/vmware-ansible . These playbooks will guide you from start to finish to deploying OCP on VMware...

This article describes how to get started with the Java S2I container image, but first, let’s discuss why having a Java S2I image is so important. Why Java S2I? The Java S2I image enables developers to automatically build, deploy and run java applications on demand, in OpenShift Container Platform, by simply specifying the location...

As a consultant for Red Hat, I have the privilege of seeing many customers. Some of them are working to find ways to split their applications in smaller chunks to implement the microservices architecture. I’m sure this trend is generalized even outside my own group of the customers. There is undoubtedly hype around microservices. Some organizations are moving toward microservices because it’s a trend, rather than to achieve a clear and measurable objective. In the process, these organizations are missing...

In part one of this series of blog posts, we discussed the importance of the user experience within the mobile industry, and how your API has a significant role in this. We followed up with part two , which demonstrates how to make API responses smaller and therefore use less network and fewer battery resources for mobile consumers. In this post, we’ll outline a number of techniques that you can leverage on an mBaaS solution such as Red Hat Mobile...
