Combining Quarkus with Red Hat OpenShift provides an ideal environment for creating scalable, fast, and lightweight applications. Quarkus significantly increases developer productivity with tooling, pre-built integrations, application services, and more. This article presents 10 reasons why you should develop your Quarkus applications on OpenShift.

After many months of waiting, Apache Camel K 1.0 is finally here! This groundbreaking project introduces developers to cloud-native application development and automated cloud configurations without breaking a sweat. With the 1.0 general availability (GA) release, Apache Camel K is more stable than ever, with performance improvements that developers will appreciate.

Deploying enterprise-grade runtime components into Kubernetes can be daunting. You might wonder:
- How do I fetch a certificate for my app?
- What’s the syntax for autoscaling resources with the Horizontal Pod Autoscaler?
- How do I link my container with a database and with a Kafka cluster?
- Are my metrics going to Prometheus?
- Also, how do I scale to zero with Knative?
Operators can help with all of those needs and more. In this article, I introduce three Operators—Runtime Component Operator, Service Binding Operator, and Open Liberty Operator—that work together to help you deploy containers like a pro.

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.

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.

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.
