An Arduino Uno switches an LED on/off based on the AWS device shadow.
This setup could be replicated with practically any host microcontroller.

A CCM module (which is an ESP-WROOM-32 hardware module) could provides device shadow connectivity ...

Yes, Go.
Delivered as a docker image container, runnable anywhere.

Both Arduino and ESP-IDF are supported!

Functionality:
1. Over-the-Air firmware update via Web UI or RESTful API .
2. Remote device management. Register/export your own management functions on a device, for example ...

Yes indeed!

Mongoose OS implementation is based on ESP-IDF, in fact we've submitted some patches during our work that has been integrated into ESP-IDF. The point is: Mongoose OS makes flash encryption process very easy - that's a single command. Otherwise, it is not trivial to do in a real firmware.
