Creating event sources in the OpenShift 4.5 web console

Creating event sources in the OpenShift 4.5 web console

Red Hat OpenShift 4.5 makes it easier than ever to deploy and run event-driven applications that react to real-time information via event notifications. Empowered by OpenShift Serverless, applications come to life through events, scaling up resources as needed (or up to a pre-configured limit), and then scaling back to zero after the resource burst is over.

Kourier: A lightweight Knative Serving ingress

Kourier: A lightweight Knative Serving ingress

Until recently, Knative Serving used Istio as its default networking component for handling external cluster traffic and service-to-service communication. Istio is a great service mesh solution, but it can add unwanted complexity and resource use to your cluster if you don’t need it.

That’s why we created Kourier: To simplify the ingress side of Knative Serving. Knative recently adopted Kourier, so it is now a part of the Knative family! This article introduces Kourier and gets you started with using it as a simpler, more lightweight way to expose Knative applications to an external network.

Let’s begin with a brief overview of Knative and Knative Serving.

Six reasons to love Camel K

Six reasons to love Camel K

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.

Serverless applications made faster and simpler with OpenShift Serverless GA

Serverless applications made faster and simpler with OpenShift Serverless GA

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.

What’s new in the OpenShift 4.4 web console developer experience

What’s new in the OpenShift 4.4 web console developer experience

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.

Build and deploy a serverless app with Camel K and Red Hat OpenShift Serverless 1.5.0 Tech Preview

Build and deploy a serverless app with Camel K and Red Hat OpenShift Serverless 1.5.0 Tech Preview

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.

Knative Cookbook: Building Effective Serverless Applications with Kubernetes and OpenShift

Knative Cookbook: Building Effective Serverless Applications with Kubernetes and OpenShift

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.
