There is a lot of buzz going around about Internet of Things, IoT. Laptops, tablets, phones, devices, glasses, watches, bands and even clothing are now connected to the cloud. But how do you start? What devices are there that I can use if I want to build something and what services are there ready for me to be consumed in the cloud? In this demo packed session we’ll show a lot of demos and code that show and inspire you to build your own gadgets that connect to the cloud. We will touch on a lot of services in Microsoft Azure that will help you realize that affordable and scalable backend you’ll need once your device becomes the next viral thing on the Internet. Even if this session has a theme of using devices connected to the cloud, all of the services we use in Azure are as useful without any device in other scenarios.
