Sure it is easy to use a web interface to build, manage, and monitor your Cloud PaaS instances. But it can be much easier to reuse several Java libraries, do REST calls, and leverage your PaaS SDKs with the Nashorn Javascript engine. In this session you will learn how to code useful Nashorn Javascripts to automate all the boring tasks you used to do in your browser. You will see examples for creating instances, diagnosting their health, scaling up and down your infrastructure, and a bonus for building a JavaFX interface without compiling a single line of code, just using Nashorn. Say no more to bash scripts. It's time to code Javascript in your Unix box!
