Apache Camel K is a lightweight cloud-integration platform that runs natively on Kubernetes and, in particular, lets you automate your cloud configurations. Based on the famous Apache Camel, Camel K is designed and optimized for serverless and microservices architectures. In this article, I discuss six ways that Camel K transforms how developers work with Kubernetes, Red Hat OpenShift, and Knative on cloud platforms.

Red Hat OpenShift Serverless delivers Kubernetes-native, event-driven primitives for microservices, containers, and compatible Function-as-a-Service (FaaS) implementations. OpenShft Serverless provides out-of-the-box traffic routing and security capabilities. This offering combines Red Hat Operators, Knative, and Red Hat OpenShift. Combined, these tools allow stateless and serverless workloads to run across OpenShift deployments on private, public, hybrid, or multi-cloud environments with automated operations.
OpenShift Serverless is now generally available. It enables developers to focus purely on building next-generation applications with a wide choice of languages, frameworks, development environments, and other tools for writing and deploying business-differentiating applications.

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.

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.

With the growing number of APIs and microservices, the time given to creating and integrating them has become shorter and shorter. That’s why we need an integration framework with tooling to quickly build an API and include capabilities for a full API life cycle. Camel K lets you build and deploy your API on Kubernetes or Red Hat OpenShift in less than a second. Unbelievable, isn’t it?
For those who are not familiar with it, Camel K is a subproject of Apache Camel with the target of building a lightweight runtime for running integration code directly on cloud platforms like Kubernetes and Red Hat OpenShift. It was inspired by serverless principles, and it will also target Knative shortly. The article by Nicola Ferraro will give you a good introduction.
In this article, I’ll show how to build an API with Camel K. For that, we will start first by designing our API using Apicurio Studio, which is based on the OpenAPI standard, and then we will provide the OpenAPI standard document to Camel K in order to implement the API and deploy it to Red Hat OpenShift.

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.
