IoT nodesSimplified view

Principles:

ü Send / receive messagesü Store / retrieve file(s)ü Write / read database

Programming languages:ü C#, Javascript, Python, Java, Ruby etc.

depends on provider

Differences:

ü Security implementations:– API key– Connection string– Certificate files

ü Protocols:– http/https– mqtt/mqtts– Amqp/amqpWs
