AWS IoT provides several connectivity models to enable IoT devices to establish their connection. Currently, AWS IoT offers the following protocols:
- Message Queuing Telemetry Transport (MQTT)
- Hypertext Transfer Protocol (HTTP)
- MQTT over Websocket
We can build a connectivity model between IoT devices and the AWS IoT backend. We can categorize the IoT device platform into the following three models based on their supported connectivity:
- For an IoT device with network capabilities, if this device has all the support required by AWS IoT, then this device can access AWS IoT directly.
- The second connectivity model is to build a connection to AWS IoT through a gateway. This approach is applied for an IoT device that has network capabilities which are not supported for AWS IoT protocols.
- The last approach is to be applied to IoT devices...
