Launching the Micro Future: Grails and Micronaut

Presented by Jeff Scott Brown

Micronaut is a new JVM-based, full-stack framework for building modular, easily testable microservice applications.

Unlike reflection-based IoC frameworks, which load and cache reflection data for every single field, method, and constructor in your code, with Micronaut, your application startup time and memory consumption are not bound to the size of your codebase.

The Micronaut framework shares many core values with Grails, including the enablement of code simplicity and developer productivity.

However, Micronaut offers many additional features for a new class of applications (e.g., microservices, serverless deployments, etc.) that may not be well- suited for Grails.


Compelling aspects of the Micronaut framework include:

  • Sub-second startup time
  • Tiny processes that may run in as little as 8mb of heap
  • No runtime reflection
  • Dependency injection
  • Load balancing
  • And more!

In this talk, Jeff will demonstrate how the future of Grails, GORM, and Micronaut are linked, as well as how the Object Computing Groovy and Grails team is taking microservice development to the next level!

Jeff Scott Brown

Grails & Micronaut Co-Founder

Object Computing Partner and Grails & Micronaut Practice Lead, Jeff Scott Brown, has been doing JVM application development for as long as the JVM has existed. He has spent most of the last decade focused specifically on work related to the Grails framework and, more recently, the new Micronaut framework.

Jeff co-authored The Definitive Guide to Grails Second Edition and The Definitive Guide to Grails 2, in partnership with Grails co-founder and OCI Grails Team Lead, Graeme Rocher.

Jeff is a regular public speaker on Grails, Groovy, Micronaut, and other JVM-related technologies.
