Building modern CI/CD workflows for serverless applications with Red Hat OpenShift Pipelines and Argo CD, Part 1

Building modern CI/CD workflows for serverless applications with Red Hat OpenShift Pipelines and Argo CD, Part 1

A recent article, The present and future of CI/CD with GitOps on Red Hat OpenShift, proposed Tekton as a framework for cloud-native CI/CD pipelines, and Argo CD as its perfect partner for GitOps. GitOps practices support continuous delivery in hybrid, multi-cluster Kubernetes environments.

Build a data streaming pipeline using Kafka Streams and Quarkus

Build a data streaming pipeline using Kafka Streams and Quarkus

In typical data warehousing systems, data is first accumulated and then processed. But with the advent of new technologies, it is now possible to process data as and when it arrives. We call this real-time data processing. In real-time processing, data streams through pipelines; i.e., moving from one system to another. Data gets generated from static sources (like databases) or real-time systems (like transactional applications), and then gets filtered, transformed, and finally stored in a database or pushed to several other systems for further processing. The other systems can then follow the same cycle—i.e., filter, transform, store, or push to other systems.

Quarkus and Jakarta EE: Together, or not?

Quarkus and Jakarta EE: Together, or not?

In this article, I answer a question that I have seen asked on various forums: Will Quarkus be compatible with Jakarta EE? To understand our answer to that question, it is helpful to know the history of Quarkus and what we’re trying to achieve with it. So, please indulge me while I lay that groundwork.

A short history of Quarkus and Java EE

When Emmanuel Bernard, Jason Greene, Bob McWhirter, and I first discussed kicking off the ThornFly.x proof of concept, which would later become Quarkus, we had conversations about where Java EE (now Jakarta EE) would eventually fit. I think we all agreed that we already had the best open source implementation of Java EE in the form of WildFly and Red Hat JBoss Enterprise Application Platform (JBoss EAP). Creating yet another addition to this space seemed confusing at best. At worst, we feared that it would split our engineering and open source community efforts.

Migrate your Java apps to containers with Migration Toolkit for Applications 5.0

Migrate your Java apps to containers with Migration Toolkit for Applications 5.0

As a developer, you have probably experimented with Kubernetes. It’s also possible that you are already running several Java applications on a Kubernetes platform, maybe Red Hat OpenShift. These initial containerized applications were greenfield projects, where you enjoyed the benefits of a platform providing templated deployments, easy rollbacks, resource availability, security by default, and a manageable way to publish your services.

Now, you might be thinking, “How can I enjoy all of these benefits in my existing Java applications?” Most Java applications in production today are running on virtual machines (VMs), likely on an application platform that is not container friendly. So, how can you migrate them from the current platform to containers on Kubernetes?

It isn’t an easy task, but this is a problem that we have been working hard on for years. Red Hat’s Migration Toolkit for Applications (MTA) 5.0 is the latest resulting iteration: An assembly of tools that you can use to analyze existing applications and discover what is required to modernize them. Read on to learn MTA 5.0’s features and migration paths.

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.
