The Device Provisioning Service is a managed service running in the Azure cloud which supports automatic provisioning of IoT devices for IoT Hub.
The following sections will give a short introduction to the most important features of the Device Provisioning Service.
Azure Functions offer a way to execute custom functions in the Azure cloud.
Functions are invoked by a trigger or binding, for a example a cron style timer, an HTTP request or an event like incoming data on other Azure services, for example ServiceBus Queues and Topics, Event Hubs or Event Grids.
The functions can be hosted on Windows or Linux. Both platforms support a wide range of programming languages like JavaScript, TypeScript, C#, F#, Java, Python and Powershell.
Depending on the selected service plan, resources can be scaled out dynamically to handle an increased load and will be scaled in automatically if the load drops.
Protobuf is a great choice to transfer data from a IoT device into the cloud. This blog will show you what Protobuf is, how it can be used with C++ and Javascript and how to handle updates without breaking backwards compatibility.
We will give you an example on how to connect a Qt App with Microsoft Azure IoT Hub, make use of the Device Twin and how authorisation can be accomplished.
IoT and IIoT applications are special compared to other kinds of cloud applications as they have to deal with devices existing “outside” of data centers.
The following series of articles provide an end-to-end overview of what Microsoft Azure offers to handle some of the challenges involved in connecting an IoT Device with the Cloud.
By working through this series you will learn about the major concepts involved in getting your IoT/IIoT device connected to Microsoft Azure. In our examples we will feature Qt, Node.Js, Protobuf from Google and much more to get you started.
