From Cloud to Fog Computing and IoT
summary
Argues that IoT forces compute out of the cloud into the fog at the edge because bandwidth cannot move the flood of data, so analytics must run on edge devices and gateways; claims device count passed humans about seven years ago and is now roughly 2 devices per person, rising to 50–250 billion in five years. Gives concrete numbers: engines produce ~20 TB per flight, daily world data ~“two billion billion bytes,” CERN and LHC run Linux and OpenFlow at ~1 Tb/s, and GE’s 1% fuel saving maps to ~$30B — Linux and open source dominate the stack.
