The Internet of things (IoT) is a scenario in which objects are provided with unique identifiers and the ability to automatically transfer data over a network without requiring human interaction. The idea is that everything is connected, and is able to provide and use data. So, a water sprinkler will check the weather forecast before watering the lawn, a smart bracelet will notify the ambulance if the person wearing it has a heart attack, and the heating in our apartment will start once it gets a notification from our car that we have left work and are heading home. The presentation will give an overview of enabling technologies for the Internet of things, focusing on the cloud platforms that allow the storage, analysis and usage of device provided data. We will describe the services that such platforms provide, show you how to use them with your own devices, and overview a couple of the most widely used ones.
