Fog computing extends the cloud to be closer to the things that produce IoT data and act on it. Such devices, called fog nodes, can be deployed anywhere with a network connection, like:

  • On a factory floor
  • On top of a power pole
  • Alongside a railway track
  • In a vehicle
  • On an oil rig

A fog node is any device with computing, storage, and network connectivity.

Examples: Industrial controllers, switches, routers, embedded servers, and video surveillance cameras.
