Abstract: 

In relation to "Cloud computing," it is bringing the computing and services to the edge of the network. Fog provides data, compute, storage, and application services to end users. The distinguishing Fog characteristics are its proximity to end users, its dense geographical distribution, and its support for mobility. Services are hosted at the network edge or even end devices such as set-top-boxes or access points. Thus, it can alleviate issues the IoT (Internet of Things) is expected to produce such as reducing service latency, and improving QoS, resulting in superior user experience. Fog Computing supports emerging Internet of Everything (IoE) applications that demand real-time/predictable latency (industrial automation, transportation, networks of sensors and actuators). Thanks to its wide geographical distribution the Fog paradigm is well positioned for real time big data and real time analytics. Fog supports densely distributed data collection points, hence adding a fourth axis to the often mentioned Big Data dimensions (volume, variety, and velocity)
