The Internet of Things is finally happening at mass scale as the cost of the sensors, networks and computing power has made the economics work. There are many articles on the web that focus on the sensors, the processes and the opportunity for analytics to drive new efficiencies using IoT, so I will focus on how the data moves from place to place within the architecture. I have also written a blog post called “Why IoT Needs Messaging” that you might find interesting.
In an IoT architecture there are four different kinds of connections across which data moves:
1) device to device, 2) device to gateway, 3) gateway to data system and 4) between data systems.
