In this quickstart, you use a direct method to control a simulated device connected to your IoT hub. IoT Hub is an Azure service that lets you manage your IoT devices from the cloud and ingest high volumes of device telemetry to the cloud for storage or processing. You can use direct methods to remotely change the behavior of devices connected to your IoT hub.
