Our Snippets Of Knowledge Weekly Blog Series
In a world where everything is becoming “smart” and subsequently connected to external services, the Azure IoT Hub offers an endpoint for physical devices and services to send messages; maybe in the form of sensor readings as a JSON payload sent to the cloud for processing.
It also supports the ability to send content back to devices as part of two way communications. For example, prompting a device to update its firmware from a central location. The bi direction abilities and device level management makes the IoT Hub a better tool for device-based use cases compared to an Azure Event Hub, although both can handle message transmissions from data sources.
The IoT capabilities can also be deployed at the edge, as well as in Azure allowing for low latency and decentralised communications where required, or in environments with a constant network connection.
