FOG Computing is an advanced or extended version of cloud computing where the computing takes place at the edge of the network. Even though the increasing usage of cloud computing, there are many more issues unsolved due to the intrinsic problem of cloud computing such as changeable potential, lack of mobility support and location- awareness. It is similar to cloud computing, but is far denser in geographical distribution and location and its proximity to end users is more, which means they provide a faster end-user experience than cloud computing and have better performance. Fog computing, also termed edge computing, can address those problems by providing elastic resources and services to end users at the edge of network, while cloud computing is more about providing resources distributed in the core network. In fact, the cloudlet concept is a subset of edge computing applied to mobile networks and the fog concept is a subset of edge computing applied to Internet of Things (IoT). FOG leverages all the advantages of cloud, but is far denser than it with more geographical reach and cover This paper discusses the definition of fog computing and similar concepts, introduces representative application scenarios, and identifies various aspects of issues of fog computing systems. Paper also discuss openings and challenges.
