Change data capture (CDC) is a well-established software design pattern for a system that monitors and captures data changes so that other software can respond to those events. Using KafkaConnect, along with Debezium Connectors and the Apache Camel Kafka Connector, we can build a configuration-driven data pipeline to bridge traditional data stores and new event-driven architectures.
This article walks through a simple example.

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.

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.

Businesses are seeking to benefit from every customer interaction with real-time personalized experience. Targeting each customer with relevant offers can greatly improve customer loyalty, but we must first understand the customer. We have to be able to draw on data and other resources from diverse systems, such as marketing, customer service, fraud, and business operations. With the advent of modern technologies and agile methodologies, we also want to be able to empower citizen integrators (typically business users who understand business and client needs) to create custom software. What we need is one single functional domain where the information is harmonized in a homogeneous way.

More and more organizations are using Red Hat Single Sign-On (Red Hat SSO) as the foundation for securing user identities for enterprise and consumer applications. The focus on providing both robust security and a seamless user experience needs to be equally considered. Neither of these requirements should be compromised, especially as applications are being built for a multi-cloud world on Red Hat OpenShift.

Apache Kafka is one of the most used pieces of software in modern application development because of its distributed nature, high throughput, and horizontal scalability. Every day more and more organizations are adopting Kafka as the central event bus for their event-driven architecture. As a result, more and more data flows through the cluster, making the connectivity requirements rise in priority for any backlog. For this reason, the Apache Camel community released the first iteration of Kafka Connect connectors for the purpose of easing the burden on development teams.

Want to smoothly modernize your legacy and monolithic applications to microservices or cloud-native without writing any code? Through this demonstration, we show you how to achieve the following change data capture scenario between two microservices on Red Hat OpenShift using the combination of Syndesis, Strimzi, and Debezium.

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.
