Building Interoperable Microservice with Eclipse MicroProfile

Eclipse MicroProfile is a collection of community-driven open source specifications that define an enterprise Java microservices platform. The open source approach of MicroProfile removes reliance on any single vendor’s release cycles and makes the development of microservices a natural extension of Java EE developers existing skill sets.

This session gives an introduction to Eclipse MicroProfile and the tools available to get started building portable microservices with a minimum of effort. The features of MicroProfile will be in explained in a down-to-earth and easily understandable way.
