We are all aware of the rise of  asynchronous and reactive programing paradigms. Java has already started catching up with other newer languages like Java Script, Go, Python,… that supports this natively. Starting with Java 9 there is  possibility support for Reactive Streams. Unfortunately the shift with Java is always slower than expected.



AWS Lambda & Vertx Framework URL Shortener Backend

Intro:

Recently I stumbleupon Vertx. Event-driven, asynchronized, lightweight, reactive, highly performant, polyglot application framework. Ideal for writing micro-services. I played around with it for a while and really enjoyed the concept of serverless applications.

I developed a few apps and cases and started to wonder how to run and deploy them so that I get a 100% reliable service. I suddenly remembered the tech seminar that I attended recently, specifically session about serverless apps with AWS (Amazon Web Services) Lambda. Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources for you. Fairly similar concepts Vertx and AWS Lambda, so maybe they complement each other? As it turns out they do, Vertx can get most of your Lambdas…
