Go Reactive with Vert.x in Oracle Application Container Cloud

Digging into the microservices world? Considering reactive programming? Then you should learn more about Vert.x, a lightweight, fast, modular, high-performance, and unopinionated toolkit for building reactive applications on the JVM.

Come to this session to see how we can use Vert.x to solve common business use cases for enterprises and how to deploy Vert.x applications packaged as containers in Oracle Application Container Cloud.
