This was interesting to me since I deal with IoT analytics. In my opinion, the two true differentiators are
- Edge analytics (when some high-velocity data is processed right near the sensors because cloud-based analytics is too slow and too expensive for this task). This is referred to as “Distributed analytics (edge)” in the picture above.
- Bidirectional communication and control of endpoints. In my opinion, “true” IoT has to be bidirectional.
