Create your first serverless function with Red Hat OpenShift Serverless Functions

Create your first serverless function with Red Hat OpenShift Serverless Functions

Serverless is a powerful and popular paradigm where you don’t have to worry about managing and maintaining your application infrastructure. In the serverless context, a function is a single-purpose piece of code created by the developer but run and monitored by the managed infrastructure. A serverless function’s value is its simplicity and swiftness, which can entice even those who don’t consider themselves developers.

Supersonic, Subatomic gRPC services with Java and Quarkus

Supersonic, Subatomic gRPC services with Java and Quarkus

gRPC is an open source remote procedure call (RPC) framework. It was released by Google in 2015 and is now an incubating project within the Cloud Native Computing Foundation. This post introduces gRPC while explaining its underlying architecture and how it compares to REST over HTTP. You’ll also get started using Quarkus to implement and consume gRPC services.

Create a Kubernetes Operator in Golang to automatically manage a simple, stateful application

Create a Kubernetes Operator in Golang to automatically manage a simple, stateful application

A Kubernetes Operator acts as an automated site reliability engineer for its application, encoding the skills of an expert administrator in software. For example, an Operator can manage a cluster of database servers and configure and manage its application. It can also install a database cluster of a declared software version and a designated number of members.

Debezium serialization with Apache Avro and Apicurio Registry

Debezium serialization with Apache Avro and Apicurio Registry

In this article, you will learn how to use Debezium with Apache Avro and Apicurio Registry to efficiently monitor change events in a MySQL database. We will set up and run a demonstration using Apache Avro rather than the default JSON converter for Debezium serialization. We will use Apache Avro with the Apicurio service registry to externalize Debezium’s event data schema and reduce the payload of captured events.
