We are very pleased to announce the general availability of .NET Core 2.1 for Red Hat Enterprise Linux and OpenShift platforms!
.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 2.1 continues to broaden its support and tools for microservice development in an open source environment. The latest version of .NET Core includes the following improvements:

For developers working on a Kubernetes-based application environment such as Red Hat OpenShift, there are a number things that need to be considered to fully take advantage of the significant benefits provided by these technologies, including:
- How do I communicate with the orchestration layer to indicate the application is operating correctly and is available to receive traffic?
- What happens if the application detects a system fault, and how does the application relay this to the orchestration layer?
- How can I accurately trace traffic flow between my applications in order to identify potential bottlenecks?
- What tools can I use to easily deploy my updated application as part of my standard toolchain?
- What happens if I introduce a network fault between my services, and how do I test this scenario?
These questions are central to building container-native solutions. At Red Hat, we define container-native as applications that conform to the following key tenets:
- DevOps automation
- Single concern principle
- Service discovery
- High observability
- Lifecycle conformance
- Runtime confinement
- Process disposability
- Image immutability
This may seem like a lot of overhead on top of the core application logic. Red Hat OpenShift Application Runtimes (RHOAR) and Istio provide developers with tools to adhere to these principles with minimal overhead in terms of coding and implementation.
In this blog post, we’re specifically focusing on how RHOAR and Istio combine to provide tools for DevOps automation, lifecycle conformance, high observability, and runtime confinement.

I’m heading back to my friends in Scotland to speak at the JBoss User Group (JBug) Scotland next month. It’s a fun group of people who really seem to enjoy working with open source and JBoss software stacks.
First off, on June 6th there will be a wonderful tech talk on application modernization and migration. This is followed by the JBug Scotland hosting a hands-on workshop. Come and get hands-on experience in a workshop showcasing application development in the cloud using containers, JBoss middleware, services, business logic, and APIs.
The events are on June 6th, 2018 from 14:00 onwards and are scheduled as follows.

Without proper testing, we should not ship any container. We should guarantee that a given service in a container works properly. Meta Test Family (MTF) was designed for this very purpose.
Containers can be tested as “standalone” containers and as “orchestrated” containers. Let’s look at how to test containers with the Red Hat OpenShift environment. This article describes how to do that and what actions are needed.
MTF is a minimalistic library built on the existing Avocado and behave testing frameworks, assisting developers in quickly enabling test automation and requirements. MTF adds basic support and abstraction for testing various module artifact types: RPM-based, Docker images, and more. For detailed information about the framework and how to use it check out the MTF documentation.

You’re in an IT department. How does the rest of the organization see you? As a valuable asset whose code and APIs make a difference in the marketplace, or as a necessary evil that should be trimmed as much as possible? Containers, microservices, and serverless computing can make you more responsive, flexible, and competitive, which in turn makes your organization more effective. And that puts you solidly in the asset column.
After sprinting through the streets of San Francisco from the stage of the opening keynote at Red Hat Summit 2018 (replay available here), Burr Sutter hosted a packed house in Moscone South to talk about these technologies. Containers are widely accepted (see the announcement from Red Hat and Microsoft for an example), microservices are increasingly popular as an approach to modernizing monolithic applications, and serverless computing is emerging as an important new programming model.

Using Istio with Red Hat OpenShift and Kubernetes makes life with microservices easier. Tucked away inside of Kubernetes pods, using the Istio service mesh, your code can run (mostly) in isolation. Performance, ease-of-changes, tracing, and so on are made available by simply using the Istio sidecar container model. But what if you want your microservice to talk to another service that is outside of your OpenShift/Kubernetes/pods environment?
Enter Istio Egress.
[This is part nine of my ten-part Introduction to Istio series. My previous article was Part 8: Istio Smart Canary Launch: Easing into Production.]

A new release stream of Red Hat JBoss Enterprise Application Platform is now available: JBoss EAP continuous delivery (JBoss EAP CD).
JBoss EAP CD provides rapid incremental releases of new JBoss EAP capabilities approximately every quarter and is delivered only in Red Hat OpenShift image format.
What does this new JBoss EAP CD release stream mean for developers?

Cloud-native application development is the new paradigm for building applications and although is it often mistaken for microservices, it is much more than that and encompasses not only the application architecture but also the process through which applications are built, deployed, and managed.
New apps are often seen as the focus of cloud-native applications; however, we believe existing and new applications are alike and can incorporate cloud-native practices if they have the four defining characteristics of cloud-native applications:
- Service-based: Build modular loosely coupled services (for example, microservices).
- API-driven: Expose services via lightweight technology-agnostic APIs.
- Containers: Package and deploy in containers as a portable unit of compute.
- DevOps: Adopt agile and DevOps principles.
The Getting Started with Cloud-Native Apps lab at Red Hat Summit 2018, which takes place in San Francisco on May 8–10, has a packed agenda that focuses on walking participants through the principles of building and operating cloud-native applications.

The community editions of JBoss Tools 4.5.3 and JBoss Developer Studio 11.3 for Eclipse Oxygen.3a are here waiting for you. Check it out!
JBoss Developer Studio comes with everything pre-bundled in its installer. Simply download it from our JBoss Products page and run it like this:
java -jar jboss-devstudio-<installername>.jar
JBoss Tools or Bring-Your-Own-Eclipse (BYOE) JBoss Developer Studio require a bit more:
This release requires at least Eclipse 4.7 (Oxygen) but we recommend using the latest Eclipse 4.7.3a Oxygen JEE Bundle since then you get most of the dependencies preinstalled.
Once you have installed Eclipse, you can either find us on the Eclipse Marketplace under “JBoss Tools” or “Red Hat JBoss Developer Studio”.
For JBoss Tools, you can also use our update site directly.
What is new?
