Micronaut is a modern, JVM-based, full stack microservices framework designed for building modular, easily testable Micro Service applications in Java, Kotlin or Groovy. Micronaut is developed by the creators of Grails and takes inspiration from lessons learnt over the years building real-world applications from monoliths to microservices using Spring, Spring Boot and Grails.
Jeff Brown, Grails and Micronaut co-founder, has been doing JVM application development for as long as the JVM has existed and has spent most of the last decade focused specifically on work related to the Grails framework.
Jeff co-authored The Definitive Guide To Grails Second Edition, and The Definitive Guide To Grails 2, with Grails founder and OCI Grails Development Lead, Graeme Rocher. Jeff is a regular public speaker on Grails, Micronaut, Groovy, and other JVM-related technologies.
