Saturday May 30th was the first NextBuild developer's conference in Eindhoven at the High Tech Campus. The conference is free for attendees and offers a variety of subjects presented by colleague developer's. This meant all talks were very practical and covered subjects encountered in real projects.

After the keynote the conference tracks were separated into five rooms, so sometimes it was difficult to choose a track. I went to the talk by my JDriven colleague Rob Brinkman about a Westy tracking platform he built with Vert.x, Groovy, AngularJS, Redis, Docker and Gradle.

This is all combined with other trip details and information in a web application. Every works with push events and the information is updated in real time in the web application. The talks was very interesting and really shows also the power and elegance of Vert.x. Also the architecture provided is a like a blueprint for Internet of Things (IoT) applications.
