ASP.NET Core is the web framework for .NET Core. Performance is a key feature. The stack is heavily optimized and continuously benchmarked. Kestrel is the name of the HTTP server. In this blog post, we’ll replace Kestrel’s networking layer with a Linux-specific implementation and benchmark it against the default out-of-the-box implementations. The TechEmpower web framework benchmarks are used to compare the network layer performance.

I’m extremely pleased to announce the release of Red Hat Container Development Kit (CDK) 3.5 and Red Hat Developer Studio 12. Whether you are developing traditional or cloud-based applications and microservices, you can run these tools on your Windows, macOS, or Red Hat Enterprise Linux laptop to streamline development:
- Red Hat Container Development Kit provides a pre-built container development environment to help you develop container-based applications quickly using Red Hat OpenShift and Kubernetes.
- Red Hat Developer Studio (previously named JBoss Developer Studio) provides a desktop IDE with superior support for your entire development lifecycle. It includes a broad set of tooling capabilities and support for multiple programming models and frameworks. Developer Studio provides broad support for working with Red Hat products and technologies including middleware, business automation, and integration, notably Camel and Red Hat Fuse. Developer Studio is based on Eclipse 4.8 (Photon).
A number of Red Hat Enterprise Linux (RHEL) development tools have been updated. These include Rust 1.26.1, Go 1.10.2, Cargo 1.26, and Eclipse 4.8 (Photon).
Our goals are to improve usability of our tools for developers, while adding new features that matter most for users of Red Hat platforms and technologies.
Overview of new features:

Containers are the new way of deploying applications. They provide an efficient mechanism to deploy self-contained applications in a portable way across clouds and OS distributions. In this blog post we’ll look at what OpenShift brings for .NET Core specifically.
Kubernetes and OpenShift
Kubernetes is the de facto orchestrator for managing containerized applications. Google open-sourced Kubernetes in 2014 and Red Hat was one of the first companies to work with Google on Kubernetes. Red Hat is the 2nd leading contributor to the Kubernetes upstream project.
OpenShift is an open-source DevOps platform that is built on top of Kubernetes. It integrates directly with your application’s source code. This enables continuous integration/continuous deployment (CI/CD) workflows. Tools are available to scale and monitor your applications. The OpenShift Catalog makes it easy to setup middleware and databases. OpenShift comes with comprehensive documentation to install and manage your installation. It can run on-prem and on public clouds such as AWS, GCP and Azure.

Red Hat Container Development Kit (CDK) provides a single-node Red Hat OpenShift cluster designed to assist with containerized application development. This environment is like a production OpenShift environment, but it is designed to work on a single user’s computer. For this purpose, CDK runs Red Hat Enterprise Linux and Red Hat OpenShift Container Platform in a virtual machine.
Follow these steps to install CDK 3.4 on Fedora 28:
- Set up the virtualization environment.
- Install and configure CDK.
- Start CDK.
Below are details for performing these steps.

We’re extremely pleased to announce additions and updates to our suite of Red Hat Developers desktop tooling products, including Container Development Kit 3.4, JBoss Developer Studio 11.3, and our DevSuite 2.3 installer. These updates are a continuation of our efforts to increase developer usability, while adding new features that matter most for users of Red Hat platforms and technologies.
New features in this release
This release has the following updated tools:

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?

If you are like me, you probably prefer to install new and exploratory software in a fresh virtual machine (VM) or container to insulate your laptop/desktop from software pollution (TM). Red Hat Container Development Kit (CDK) relies on virtualization to create a Red Hat Enterprise Linux (RHEL) virtual machine to run OpenShift (based on Kubernetes). Red Hat specifically supports installation of the CDK on Windows, macOS, and RHEL Server, but if you are running Fedora, RHEL Workstation, or even CentOS, you will run into trouble. If you are not running a supported desktop, you can always use a RHEL Server virtual machine, and this tutorial is for you.

I’m extremely pleased to announce additions and updates to our Red Hat Development Suite of products, including Container Development Kit 3.3, JBoss Developer Studio 11.2, and our DevSuite 2.2 installer. These updates are a continuation of our efforts to increase developer usability, while adding new features that matter most for targeting Red Hat platforms.
Red Hat Development Suite is a curated, integrated set of desktop tools especially suited for developing Linux container-based microservices that can be deployed on Red Hat Enterprise Linux, OpenShift Container Platform, and other Red Hat platforms. In addition to the components listed above, it also enables easy installation of JBoss Enterprise Application Platform, JBoss Fuse and Kompose (tech preview), as well as numerous complementary pieces required to get an integrated development platform configured and running on your desktop. It combines these components in an easy-to-use installer to make setup simple for Windows, macOS and RHEL.

Recently, there has been a lot of buzz about two seemingly different products: Red Hat OpenShift and Microsoft Visual Studio Code (VSCode). Thanks to the help of Red Hat, the Java language is now supported inside of VSCode development environment. As Java is a first class citizen in Red Hat OpenShift, we will see how it is possible to debug your Java code running inside containers on OpenShift (thanks to Red Hat Container Development Kit) from within the VSCode IDE running on your desktop.

If you’re a Red Hat Container Development Kit (CDK) or upstream Minishift user, you would have been affected by the unavailability of nip.io. When you create a route for an application running in OpenShift (provided by Minishift) it uses nip.io for routing to the Minishift VM IP address. As a result, it is impossible to access the route created with nip.io suffix.
