An introduction to microservices through a complete example Today I want to talk about the demo we presented @ OpenShift Container Platform Roadshow in Milan & Rome last week. The demo was based on JBoss team's great work available on this repo: https://github.com/jbossdemocentral/coolstore-microservice In the next few paragraphs, I'll describe in deep detail the microservices CoolStore example and how we used it for creating a great and useful example of DevOps practices. We made some edits to the original project...

The Concept of Auto Scaling and Scaling SAFSMS (SAF School Management Software) In 2008, I have heard about Cloud Computing and AWS. But frankly, the more I wanted to understand what cloud computing is the more I got confused. I have stumbled upon a number of marketing videos using the hype of Cloud Computing to even confuse me more. Two years later, we have launched the web version of our result compiler software that will enable parents to access their...

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...

You may have read or heard that we folded DevNation into Red Hat Summit this year, which means that every Summit attendee has access to developer-related sessions, labs, and more! Here are some highlights to look forward to at Red Hat Summit (and why you should attend): LOTS of developer content. This is possibly the largest Red Hat-hosted commercial developer event ever with nearly 150 developer-related sessions, labs, BoFs, Lightning talks, CodeStarters [1], classes, and demos, plus nearly 50 Red...

A year ago Red Hat announced the availability of a no-cost Red Hat Enterprise Linux developer subscription available as part of the Red Hat Developer Program. Offered as a self-supported, development-only subscription, this developer subscriptions provides you with a stable development platform for building enterprise applications - across cloud, physical, virtual, and container-centric infrastructures. Adoption has been excellent since then, but I was prompted (aka nudged, voluntold) to remind "non users" (yes, some of you are still out there) what...

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...

What can be done to help the OpenJDK JVM play well in the world of Linux Containers? I thought I'd start tackling this issue by answering some frequently asked questions: Why is it when I specify -Xmx=1g my JVM uses up more memory than 1gb of memory? Specifying -Xmx=1g is telling the JVM to allocate a 1gb heap. It's not telling the JVM to limit its entire memory usage to 1gb. There are card tables, code caches, and all sorts...

An in-memory data grid is a distributed data management platform for application data that: Uses memory (RAM) to store information for very fast, low-latency response time, and very high throughput. Keeps copies of that information synchronized across multiple servers for continuous availability, information reliability, and linear scalability. Can be used as distributed cache, NoSQL database, event broker, compute grid, and Apache Spark data store. The technical advantages of an in-memory data grid (IMDGs) provide business benefits in the form of...

If you're are anything like me, you find the easiest -- yet still best -- way to get things done. After all, life is too short to write programs using Edlin, so give me Visual Studio Code (VS Code). So, what's an easy way for a Windows .NET developer to write code for Linux? Enter the Red Hat Development Suite, a zero-cost bundle for running Linux on your Windows PC, including running .NET Core. After installing the Red Hat Development...

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...
