In this contemporary era, although with the increasing usage of cloud computing, there are still some challenges which are unresolved such as real time latency, lack of mobility support, low capacity, network failure etc. Fog computing can deal with these problems by providing expandable resources and services to the end users, at the edge of network, while cloud computing are more about providing resources distributed in the core network. Generally, Fog computing resides closer to the devices that extend the Cloud-based computing, storage and networking facilities. These devices, called fog nodes, can be deployed anywhere with a network connection: on a factory floor, on top of a power pole, alongside a road or train track, in any automobile vehicle. Any device with computing, storage, and network connectivity can be a fog node. In this comparative study, we elaborate the comparison among cloud and fog on the basis of some parameters like security and privacy issues, data processing, architecture etc. and Finally, this paper also enlighten how fog computing have cutting edge over cloud computing.
