Real-time alerts with Azure functions

Azure functions are small running pieces of code, or functions, in the cloud. You can write small pieces of code that you need for a specific problem without worrying about the complete application or the infrastructure where we can run it.

There are various existing connectivity options available along with language support.

We will be exposing communication with IoT Hub and exploring how Azure functions can work with our small piece of code.

How to do it...

We will create a Azure function and see how to access IoT Hub real time:

1. We will continue to use the IoT Hub IoTHubCookBook we created earlier.
2. Select the Azure function app from new – compute:

3. Create a new function app...
