I am rather surprised I haven't seen an AWS IoT alternative that sits on top of something like NATS. I feel like this could be low hanging fruit to write a service that does most of the things AWS IoT does by pub/sub-ing to all the $aws/* reserved topics and implementing them with NATS as the MQTT broker.

https://docs.aws.amazon.com/iot/latest/developerguide/reserved-topics.html

This would be especially nice for implementing:

• Thing Shadows
• Events
• Jobs
