Fog computing is an evolving technology that brings the benefits achieved by cloud computing to the periphery of the network devices for faster data analytics. This has triggered the usage of fog computing for enabling a new breed of applications and services that require localized and faster decision making. Fog computing has attributes such as location awareness, edge deployment and a large number of geographically distributed nodes, heterogeneity through which fog computing offers better performance in terms of mobility, low latency, and real-time interaction. They can also gracefully handle enormous data flow and provide analytics in reasonable time. Due to these additional attributes, fog computing is considered as the appropriate platform for many applications and especially suited for internet of things (IoT). Fog computing also provides an intelligent platform to manage the distributed and real-time nature of emerging IoT applications and infrastructures. With the increase in the number of connected objects, the development of fog computing is tremendous and has promising technological future growth.
