edge, IoT
Margaret Martonosi, professor at Princeton University, suggests that processing data closer to or within sensors and devices -- and not sending it out to the cloud -- may accomplish more, in a more secure way, and more economically.
Edge computing or fog computing—a paradigm championed by some of the biggest IoT technology players, including Cisco, IBM, and Dell—represents a shift in architecture in which intelligence is pushed from the cloud to the edge, localizing certain kinds of analysis and decision-making.

As stated in the Microsoft blog post, “Cloud is a natural place to manage IoT devices, to collect data from them, gain insights using analytics and then operationalize those insights. Edge is a natural place to collect, optimize and react to data with low latency based on the insights generated in the cloud. In this way, cloud and edge work together to help IoT reach its full potential.”
