Live Coding Reactive Systems w/Eclipse Vert.x and OpenShift
Do you know the battery level in your smartphone is controlled by reactive software; which is software that reacts to a set of external events, such as requests, failures, availability of services, etc? This was what I recently addressed as a slideless session consisting of pure, live coding at the Red Hat Summit this past May.
The goal was to develop two microservices completely asynchronous focusing on responsiveness in 40 minutes running inside of OpenShift. I wanted to build a reactive system, a distributed application that focused on being responsive even while there are a lot of flaws through a lot of users, and also the state of responses it faced failures, such as the services relied on are gone for whatever reason. So based on personal experience, I developed a very simple shopping list application. You can always put a list on the refrigerator but it’s not always up-to-date and is usually my fault although I’m pretty sure my wife continues to add items to it but does not tell me besides my way is cooler.
