MQTT-based file delivery
One option you can use to manage files and transfer them to AWS IoT devices in your fleet is MQTT-based file delivery. With this feature in the AWS Cloud you can create a stream that contains multiple files, you can update stream data (the file list and descriptions), get the stream data, and more. AWS IoT MQTT-based file delivery can transfer data in small blocks to your IoT devices, using the MQTT protocol with support for request and response messages in JSON or CBOR.
