Imagine that we have to create a RESTful API to control a drone, also known as an Unmanned Aerial Vehicle (UAV). The drone is an IoT device that interacts with many sensors and actuators, including digital electronic speed controllers linked to engines, propellers, and servomotors.
The IoT device has limited resources, and therefore, we have to use a lightweight Web framework. Our API doesn't need to interact with a database. We don't need a heavyweight Web framework like Django, and we want to be able to process many requests without blocking the Web server. We need the Web server to provide us with good scalability while consuming limited resources. Thus, our choice is to use Tornado, the open source version of FriendFeed's Web server.
The IoT device is capable of running Python 3.5, Tornado, and other Python packages. Tornado is a Python Web framework and an asynchronous networking library that provides excellent scalability...
