Azure Iot hub client communication with multiple devices

Question

I have a node.js server application that communicates with Iot devices using Azure IoT Hub service.

When I examine the sample code sample code from Azure repository about cloud to device message. I see that one client was created. If there are multiple devices and multiple messages to be sent to multiple devices, is it okay to create multiple Iot hub clients, or should I stick to one client solution. What could be the cons and pros of two approach?

Answer 1

Have a look at the Azure IoT Hub feature for your scenario such as a Schedule and broadcast jobs. This feature enables a cloud back-end to schedule and update millions of devices based on your needs.
