I recently decided it was time for me to take a shot at passing another few Microsoft exams. While studying for one of them, I noticed that I didn’t knew too much about Azure IoT Hub. I had never come across it in my daily job. So I gave myself the following goal: have something that acts as an IoT device that sends data into Azure IoT Hub and have something read that data and does something useful with it. When talking about the data that comes out of IoT Hub we usually split that into a hot and/or cold analytics path, in this blog I’ll show you an example of both.
