Announcing Red Hat CodeReady Studio, the latest evolution of Red Hat Developer Studio

By Bob Davis April 2, 2019April 2, 2019

Red Hat has been shipping a distribution of Eclipse IDE for years now, including all of the great features of Eclipse along with the add-ons, plugins, and tooling that make working with our products easy and enjoyable. These distributions have gone by different names over the years to indicate how they fit into the Red Hat ecosystem, and to tap into the trust that developers have when they think about Red Hat and what a Red Hat product means for them: it’ll be reliable; it’ll have a published lifecycle; it’s built from source; and if you submit a bug, we’ll fix it (and give the fix to the community). This change is no different.

Red Hat CodeReady Studio is the latest evolution of Red Hat Developer Studio, which itself was an evolution of JBoss Developer Studio. We’re proud to include our distribution of Eclipse IDE in the expanding CodeReady portfolio. Based on the latest Eclipse 4.11, with the latest additions of JBoss Tools and end-to-end testing that ensures everything works as expected, developers can count on the same great experience they’ve grown used to. With tools for working with Fuse and other middleware products and connectors for Red Hat OpenShift that enable super-fast, container-native “inner loop” development cycles, CodeReady Studio is absolutely one of the best desktop IDEs an enterprise Java^TM developer can use.

IoT edge development and deployment with containers through OpenShift: Part 1

By Alessandro Arrichiello January 31, 2019February 5, 2019

Usually, we think about IoT applications as something very special made for low power devices that have limited capabilities. For this reason, we tend to use completely different technologies for IoT application development than the technology we use for creating a datacenter’s services.

This article is part 1 of a two-part series. In it, we’ll explore some techniques that may give you a chance to use containers as a medium for application builds—techniques that enable the portability of containers across different environments. Through these techniques, you may be able to use the same language, framework, or tool used in your datacenter straight to the “edge,” even with different CPU architectures!

We usually use “edge” to refer to the geographic distribution of computing nodes in a network of IoT devices that are at the “edge” of an enterprise. The “edge” could be a remote datacenter or maybe multiple geo-distributed factories, ships, oil plants, and so on.

Integration of storage services (part 6)

By Eric D. Schabell January 18, 2019January 21, 2019

In Part 5 this series, we looked into details that determine how your integration becomes the key to transforming your customer experience.

It started with laying out the process of how I’ve approached the use case by researching successful customer portfolio solutions as the basis for a generic architectural blueprint. Now it’s time to cover various blueprint details.

This article covers the final elements in the blueprint, storage services, which are fundamental to the generic architectural overview.

Automating tests and metrics gathering for Kubernetes and OpenShift (part 3)

By Frédéric Giloux January 16, 2019January 22, 2019

This is the third of a series of three articles based on a session I held at Red Hat Tech Exchange EMEA. In the first article, I presented the rationale and approach for leveraging Red Hat OpenShift or Kubernetes for automated performance testing, and I gave an overview of the setup. In the second article, we looked at building an observability stack. In this third part, we will see how the execution of the performance tests can be automated and related metrics gathered.

An example of what is described in this article is available in my GitHub repository.

Announcing .NET Core 2.2 for Red Hat Platforms

By Bob Davis December 5, 2018December 5, 2018

We are very excited to announce the general availability of .NET Core 2.2 for Red Hat Enterprise Linux and OpenShift platforms! This general availability is in lock-step with Microsoft’s release yesterday.

.NET Core is the open-source, cross-platform .NET platform for building microservices. .NET Core is designed to provide the best performance at scale for applications that use microservices and containers. Libraries can be shared with other .NET platforms, such as .NET Framework (Windows) and Xamarin (mobile applications). With .NET Core you have the flexibility of building and deploying applications on Red Hat Enterprise Linux or in containers. Your container-based applications and microservices can easily be deployed to your choice of public or private clouds using Red Hat OpenShift. All of the features of OpenShift and Kubernetes for cloud deployments are available to you.

.NET Core 2.2 continues to broaden its support and tools for application development in an open source environment. The latest version of .NET Core includes the following improvements:

Quickly try Red Hat Process Automation Manager in your cloud

By Eric D. Schabell December 4, 2018

It’s been some time since I last talked with you about putting JBoss BPM Suite (now called Red Hat Process Automation Manager) into your cloud, and with the new release, it’s time to talk AppDev in the cloud again.

It’s time to update the story and see how to put Red Hat Process Automation Manager in your cloud so you are set up with a standard configuration to start your first business rules project.

With the easy installation demo project described below, you can leverage process automation tooling through the business central web console running containerized on any Red Hat OpenShift.

Let’s take a closer look at how this works.

EventFlow: Event-driven microservices on OpenShift (Part 1)

By Hugo Hiden and Matthias Wessendorf and Simon Woodman October 15, 2018October 14, 2018

This post is the first in a series of three related posts that describes a lightweight cloud-native distributed microservices framework we have created called EventFlow. EventFlow can be used to develop streaming applications that can process CloudEvents, which are an effort to standardize upon a data format for exchanging information about events generated by cloud platforms.

The EventFlow platform was created to specifically target the Kubernetes/OpenShift platforms, and it models event-processing applications as a connected flow or stream of components. The development of these components can be facilitated through the use of a simple SDK library, or they can be created as Docker images that can be configured using environment variables to attach to Kafka topics and process event data directly.

Container-native integration testing

By Raffaele Spazzoli August 2, 2018October 19, 2018

Integration testing is still an important step in a CI/CD pipeline even when you are developing container-native applications. Integration tests tend to be very resource-intensive workloads that run for a limited time.

I wanted to explore how integration testing technologies and tools could leverage a container orchestrator (such as Red Hat OpenShift) to run faster and more-dynamic tests, while at the same time using resources more effectively.

In this post, you will learn how to build behavior-driven development (BDD) integration tests using Cucumber, Protractor, and Selenium and how to run them in OpenShift using Zalenium.

The code for the example of this article can be found on GitHub in redhat-cop/container-pipelinesh.
