The developer experience in the Red Hat OpenShift Container Platform web console keeps getting better. You’ve probably already heard about our streamlined user flows to build and deploy applications, plus the ability to understand the structure of your application via the Topology view. Each new release of Red Hat OpenShift includes usability improvements and new features to help developers reach their goals.
In OpenShift 4.4, we focused on making application deployment easier through the Developer Catalog, improving the experience of Operator-backed services, and supporting Helm Charts. As for feature updates, we:
- Made a number of topology enhancements to help streamline discoverability and scalability.
- Introduced an application monitoring section.
- Introduced a new Pipeline Builder.

Red Hat OpenShift Serverless 1.5.0 (currently in tech preview) runs on Red Hat OpenShift Container Platform 4.3. It enables stateful, stateless, and serverless workloads to all operate on a single multi-cloud container platform. Apache Camel K is a lightweight integration platform that runs natively on Kubernetes. Camel K has serverless superpowers.
In this article, I will show you how to use OpenShift Serverless and Camel K to create a serverless Java application that you can scale up or down on demand.

Serverless architecture has recently taken center stage in cloud-native application deployment: Enterprises started to see the benefits that serverless applications bring to them, such as agility, rapid deployment, and resource cost optimization. As with any other new technology, there were multiple ways to approach and employ serverless technologies, such as Function-as-a-Service (FaaS) and Backend-as-a-Service (BaaS)—that is, running your applications as ephemeral containers—with the ability to scale up and down automatically.

DevNation tech talks are hosted by the Red Hat technologists who create our products. These sessions include real solutions and code and sample projects to help you get started. In this presentation, you’ll learn about the serverless developer experience on Kubernetes with Knative and Apache Kafka from Matthias Wessendorf.

In the past few years, developers have addressed the challenge of evolving from monolith systems to microservices architecture. These days, we hear about the adoption of serverless systems.
Like many trends in software, there’s no one clear view of how to define serverless or how this approach offers added value for our software architecture. The perfect place to start with serverless systems and discover serverless capabilities is through a use case.

Our first DevNation Live regional event was held in Bengaluru, India in July. This free technology event focused on open source innovations, with sessions presented by elite Red Hat technologists.
In this session, Burr Sutter discusses serverless architectures, which have become a common approach in organizations that want to be more effective in DevOps and optimize their IT resources. This approach adds further flexibility to the next generation of microservices, and Knative helps running your microservices serverless workloads on Kubernetes/OpenShift be more agile and effective.

Millions of developers worldwide want to learn more about serverless computing. If you’re one of the lucky thousands attending Red Hat Summit in Boston May 7-9, you can gain hands-on experience with the help of Burr Sutter and the Red Hat Developer team.
Guru Night is a BYOL (bring your own laptop) event taking place Wednesday, May 8 from 5:00 p.m. to 8:00 p.m. at the Boston Convention and Event Center in ML2 East-258AB. (Doubtless there will be a map to show you where or what ML2 East etc. is; we have no idea.) Head to the signup page and fill out your details now.
TL;DR: Beer and pizza will be served.
We felt compelled to point that out. But read on.

You’ve probably already read about Quarkus, but you may not know that the superfast startup speed of Quarkus makes it the best candidate for working with Knative and serverless for your Function-as-a-Service (FaaS) projects.
Quarkus, also known as Supersonic, Subatomic Java, is a Kubernetes native Java stack tailored for GraalVM and OpenJDK HotSpot, crafted from the best-of-breed Java libraries and standards. Knative is a Kubernetes-based platform to build, deploy, and manage modern serverless workloads. You can learn more in this article series.
This article does not provide a full deep dive on Knative or Quarkus. Instead, I aim to give you a quick and easy way to start playing with both technologies so you can further explore on your own.

With Kubernetes evolving at supersonic speed and seeing a lot of adoption in the enterprise world, the developer community is now looking for solutions to common Kubernetes problems, such as patterns. In this article, I will explore a new Kubernetes pattern using Init Containers.
Let’s start with the use case that gave birth to this problem: Quarkus—Supersonic and Subatomic Java—has excited the Java developer community with its amazing speed and all new native build artifact for Java applications. As one of those excited developers, I want to quickly build and deploy a Quarkus application on to Kubernetes.

Are serverless and Function as a Service (FaaS) the same thing?
No, they’re not.
Wait. Yes, they are.
Frustrating, right? With terms being thrown about at conferences, in articles (I’m looking at myself right now), conversations, etc., things can be confusing (or, sadly, sometimes misleading). Let’s take a look at some aspects of serverless and FaaS to see where things stand.
