A few years ago, Cisco coined the term fog computing to describe a layer of computing at the edge side. This layer allows us to preprocess data to be transported to the IoT Hub quickly and securely. Fog computing pushes the elaboration and computation of resources to the local network and processes data in a fog node or IoT gateway. In the industrial sector, the edge has the ability to work in collaboration with a local headquarters, where it can find more computational resources before sending the data to the centralized IoT Data Hub, whether this is in the cloud or not.
