Micronaut is a new JVM-based, full-stack framework for building modular, easily testable microservice applications with Java, Kotlin, and Groovy. In this live-coding session, you will see how fast you can start developing "natively" cloud-native microservices with Micronaut. You will learn about the reactive support, testing, http-client, service discovery, fallback, and GraalVM support.
