Why?

Sadly, our main priority with learning the AWS IoT platform is not to play with connected devices, _yet_...
The situation we are in with one of our more interesting web projects is that we need a way to "push" data from backend to front. In any other project we would simply use WebSockets (e.g: Socket.io) on our Node.js server... however having a "Traditional" Server is not an option in this particular project, and given that AWS does not currently have a "WebSockets-as-a-Service" (e.g: Pusher, PubNub or Firebase ) we are forced to be "Creative"...
The IoT platform with its support for WebSockets could help us solve the issue: https://aws.amazon.com/iot/
