Before we start building IoT solutions using various out-of-the-box IoT platforms, I would like to talk about the various building blocks of an IoT solution. That includes smart devices, storage, API management, as well as intelligence.
This diagram represents an end-to-end IoT stack:
The stack consists of various layers that will be part of any typical IoT solution.
The bottommost layers in the stack are the smart devices or The Things. These communicate with the real world and gather the information around them to actuate things. And through the gateway, the smart devices talk to the device management software to keep ...
