Red Hat Runtimes brings Vert.x and Dekorate to Spring Boot 2.2.6

Red Hat Runtimes brings Vert.x and Dekorate to Spring Boot 2.2.6

The latest update to Red Hat Runtimes features support for Spring Boot 2.2.6, along with the Dekorate project and Spring Reactive. Together, these technologies are a boost for developers building Spring-based applications on the Red Hat OpenShift Container Platform. In this article, I present the highlights of this update.

Mandrel: A community distribution of GraalVM for the Red Hat build of Quarkus

Mandrel: A community distribution of GraalVM for the Red Hat build of Quarkus

The Java community has demonstrated time and time again its ability to evolve, improve, and adapt to meet the needs of its developers and users. Even after 25 years of language and framework choices, Java has consistently ranked in the top languages in use today due to its strong track record and capabilities in enterprise use cases. Red Hat has long been a strong leader in Java and open source software development and remains committed to being at the forefront of Java as it continues to evolve.

Today, Red Hat and the GraalVM community jointly established a new downstream distribution of GraalVM, called Mandrel. This distribution will power the Red Hat build of Quarkus, a recently announced addition to Red Hat Runtimes. This article explains what Mandrel is and why it is necessary.

The road to Quarkus GA: Completing the first supported Kubernetes-native Java stack

The road to Quarkus GA: Completing the first supported Kubernetes-native Java stack

I’ve had many proud moments in my role here at Red Hat over the years. Examples include when we released the first version of WildFly, when we acquired the Camel team, when we worked with other vendors to create Eclipse MicroProfile, the great work the Strimzi team did to get into the Cloud Native Computing Foundation, our entire Red Hat Managed Integration effort, Kogito, and the list goes on. I feel like I add to this list of examples on an almost weekly basis.

Well, I can now update this list with the first product release of Quarkus, formally called the Red Hat build of Quarkus. (You can also find more support options on the Quarkus project site.) It should come as no surprise that Quarkus is on this list. I suppose what might surprise some people is that Quarkus is only just a product now. Given all of the activities since we officially launched the Quarkus project in 2019, you could be forgiven for thinking it was already a product.

Quarkus, a Kubernetes-native Java runtime, now fully supported by Red Hat

Quarkus, a Kubernetes-native Java runtime, now fully supported by Red Hat

Java was introduced 25 years ago, and to this day, remains one of the most popular programming languages among developers. However, Java has developed a reputation for not being a good fit for cloud-native applications. Developers look for (and often choose) alternative frameworks such as Go and Node.js to support their cloud-native development requirements.

Why learn another language when you can use your existing skills? Quarkus allows Java developers to leverage their expertise to develop cloud-native, event-driven, reactive, and serverless applications. Quarkus provides a cohesive Java platform that feels familiar but new at the same time. Not only does it leverage existing Java standards, but it also provides a number of features that optimize developer joy, including live coding, unified configuration, IDE plugins, and more.

Recently, Red Hat announced support for Quarkus. With Quarkus, Red Hat advances Java on Kubernetes and bridges the gap between traditional Java applications and cloud-native environments.

Red Hat build of Eclipse Vert.x 3.9 brings Fluent API Query

Red Hat build of Eclipse Vert.x 3.9 brings Fluent API Query

Red Hat Runtimes provides a set of comprehensive frameworks, runtimes, and programming languages for developers, architects, and IT leaders with cloud-native application development needs. The latest update to Red Hat Runtimes has arrived with Red Hat’s build of Eclipse Vert.x version 3.9. Red Hat Runtimes provides application developers with a variety of application runtimes and lets them run on the Red Hat OpenShift Container Platform.

A fluent API is a common pattern throughout Vert.x, it lets multiple methods calls be chained together. For example:

request.response().putHeader("Content-Type", "text/plain").write("some text").end();

Chaining calls like this also allows you to write code that’s a bit less verbose.

With 3.9, you can now create prepared statements and collector queries with the inclusion of Query in the Fluent API. If you are familiar with JDBC, PreparedStatement lets you create and execute statements. Moreover, you can run multiple interactions, such as cursor or stream operations.

Modern web applications on OpenShift, Part 4: Openshift Pipelines

Modern web applications on OpenShift, Part 4: Openshift Pipelines

When I wrote part 3 of this series, Modern web applications on OpenShift: Part 3 — OpenShift as a development environment, I said that was the final part. However, there is new tech that fits in very nicely with deploying modern Web Applications to OpenShift, so part 4 is necessary. As a refresher, in the first article, we looked at how to deploy a modern web application using the fewest commands. In the second part, we took a deeper look into how the new source-to-image (S2I) web app builder works and how to use it as part of a chained build. In the third, we took a look at how to run your app’s “development workflow” on Red Hat OpenShift. This article talks about OpenShift Pipelines and how this tool can be used as an alternative to a chained build.

Ramp up on Quarkus: A Kubernetes-native Java framework

Ramp up on Quarkus: A Kubernetes-native Java framework

Java has been in a bit of an awkward spot since containers took off a few years ago. In the world of Kubernetes, microservices, and serverless, it has been getting harder and harder to ignore that Java applications are, by today’s standards, bloated. Well, until now. In this article, I explore the basics of Quarkus, a Kubernetes-native Java framework built to specifically address Java’s bloatedness problem.

Running an event-driven health management business process through end user scenarios: Part 2

Running an event-driven health management business process through end user scenarios: Part 2

If you read the first article in this series, then you already set up the example application you’ll need for this article. If you have not set up the population health management application, you should do that before continuing. In this article, we’ll run a few business processes through our event- and business-process-driven application to test it out.
