 So often developers really don't know where to get started to build their first mobile or IoT application. You're dealing with a lot of moving parts. And so from my perspective, I love the idea of making that space really easy for developers. We created the My Driving app so that developers could see a sample application that would allow them to build those kinds of apps. The My Driving app is a rich mobile experience. It's a real example of how you might take IoT sensor information from your car, combine it with sensor information from a mobile device, and basically build a stream of your driving habits that we then send to the cloud and aggregate it with not just your driving habits, but other users' driving habits so that you can get stats on, are you a good driver or not, or your trip history. You can have map information as you drive, which updates in real time. And you can also replay those trips going forward and back. We built the iOS and Android apps using Xamarin. And all of the sensor information was being sent up to the Azure IoT Hub. That hub is all about getting it to the other backend technologies such as Power BI, Azure Stream Analytics, Azure Machine Learning, just to name a few. You can really easily build an app that can go to multiple platforms, be it iOS, Android, or Windows. We spent a lot of time thinking about the architecture. We really wanted to make sure that we got a high degree of code sharing across the different mobile apps. We also wanted to make sure that we had a really great native look and feel, and then make sure that the app would scale when it's deployed into the wild. To me, the most exciting thing about this app is that it's a great learning tool. If you just download the source and you start poking around in it, you'll see how easy it is to build a mobile app or an IoT-based solution.
