Modernize your application deployment with Lift and Shift

Modernize your application deployment with Lift and Shift

For many software modernization projects, it’s all about learning to love, lift, and shift. No, wait. It’s all about learning to love lift and shift. The basic idea behind lift and shift is to modernize how an existing application is packaged and deployed. Because it’s not about rewriting the application itself, lift and shift is typically quick to implement.

Modern development environments rely on containers for packaging and deployment. A modern environment also uses a continuous integration / continuous deployment (CI/CD) system that automatically builds, tests, and deploys an application whenever its source code changes.

EclipseCon Europe: Che sessions by Red Hatters

EclipseCon Europe: Che sessions by Red Hatters

EclipseCon Europe is almost here, and many Red Hatters are working furiously to make the show as valuable as possible for attendees. (We’re partly doing it for ourselves as well, of course, because it’s a great opportunity to get the entire Che/Theia community together.)  If you aren’t familiar with Eclipse Che, it’s is a next-generation cloud IDE and developer workspace server for teams and organizations. Theia is an extensible open-source framework to develop multi-language IDEs for the cloud and desktop using state-of-the-art web technologies.

The conference will be held next week on October 22–25 in Ludwigsburg, Germany. Here’s a rundown of what will be offered.

Announcing Red Hat Developer Studio 12.9.0.GA and JBoss Tools 4.9.0.Final for Eclipse 2018-09

Announcing Red Hat Developer Studio 12.9.0.GA and JBoss Tools 4.9.0.Final for Eclipse 2018-09

Attention desktop IDE users: Red Hat Developer Studio 12.9 and the community edition, JBoss Tools 4.9.0 for Eclipse 2018-09, are now available. You can download the Developer Studio bundled installer, which installs Eclipse 4.9 with all of the JBoss Tools already configured. Or, if you have an existing Eclipse 4.9 (2018-09) installation, you can download the JBoss Tools package.

This article highlights some of the new features in both JBoss Tools and Eclipse Photon, covering WildFly, Spring Boot, Camel, Maven, and many Java-related improvements—including full Java 11 support.

Developer Studio/JBoss Tools provides a desktop IDE with a broad set of tooling covering multiple programming models and frameworks. If you are doing container/cloud development, there is integrated functionality for working with Red Hat OpenShift, Kubernetes, Red Hat Container Development Kit, and Red Hat OpenShift Application Runtimes. For integration projects, there is tooling covering Camel and Red Hat Fuse that can be used in both local and cloud deployments.

Source versus binary S2I workflows with Red Hat OpenShift Application Runtimes

Source versus binary S2I workflows with Red Hat OpenShift Application Runtimes

Red Hat OpenShift supports two workflows for building container images for applications: the source and the binary workflows. The binary workflow is the primary focus of the Red Hat OpenShift Application Runtimes and Red Hat Fuse product documentation and training, while the source workflow is the focus of most of the Red Hat OpenShift Container Platform product documentation and training. All of the standard OpenShift Quick Application Templates are based on the source workflow.

A developer might ask, “Can I use both workflows on the same project?” or, “Is there a reason to prefer one workflow over the other?” As a member of the team that developed Red Hat certification training for OpenShift and Red Hat Fuse, I had these questions myself and I hope that this article helps you find your own answers to these questions.

Running Microsoft SQL Server on Red Hat OpenShift

Running Microsoft SQL Server on Red Hat OpenShift

In this blog post, we’ll set up Microsoft SQL Server on Red Hat OpenShift. We’ll use SQL Server to store data for a simple ASP.NET Core application running in a container deployed on OpenShift that manages a list of contacts. When we have that set up, we’ll use SQL Operation Studio to connect to the server running on OpenShift from our developer machine.

Announcing Red Hat Application Migration Toolkit 4.1.0: Now with technical reports

Announcing Red Hat Application Migration Toolkit 4.1.0: Now with technical reports

[In case you aren’t following the Red Hat JBoss Middleware blog, we are reposting this article on developers.redhat.com.]

Red Hat Application Migration Toolkit (RHAMT) 4.1.0 has been released, and with it a new feature that I’d like to highlight in this article—Technology Reports.

If you’re not familiar with RHAMT, check out my previous article that introduces RHAMT and describes how you can use it to help with migration existing applications to a modern application platform by analyzing your code base.

Technology reports

This new feature in RHAMT provides an aggregate listing of the technologies used, grouped by function, for the analyzed applications. It shows how the technologies are distributed. After analysis has been performed, using this report hundreds of applications can be quickly compared. In addition, the size, number of libraries, and story point totals of each application are displayed, allowing you to quickly determine each application’s type from a single report, for example:

Improving .NET Core Kestrel performance using a Linux-specific transport

Improving .NET Core Kestrel performance using a Linux-specific transport

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.

How to migrate your SOAP web service to REST with Camel

How to migrate your SOAP web service to REST with Camel

SOAP-based services are plentiful in many enterprise solutions and are slowly being replaced by RESTful services to simplify their use. There is a new wizard to help you make the transition with Apache Camel’s Rest DSL added in the latest version of Red Hat Fuse Tooling. This article shows how to use the new wizard to transition from older SOAP-based services to more modern REST-based services.

If you aren’t familiar, Red Hat Fuse is an integration platform based on Camel and a number of other projects. The updating Fuse Tooling is available in Red Hat Developer Studio 12.0.0, the desktop IDE that is based on Eclipse 4.8 Photon. You can also get the new wizard by adding JBoss Tools 4.6 to your existing Eclipse 4.8 Photon installation by downloading it directly, or installing via the Eclipse Marketplace.
