Cloud and Fog Computing: Challenging Issues for Internet of Things and Big Data

The paper is devoted to the need for state-of-the-art trend in distributed computing - Fog computing as well as its distinctions in terms of an architecture and technical aspects with cloud computing followed by prerequisites to Fog platform so as to be able to deal with real-time Big Data obtained from evolving Internet of Things/Everything devices and wireless sensor networks. Fog computing is arguably either a virtualized platform or real equipment typically located between end user devices and the cloud data centres hosted within the Internet. As compared to Cloud computing, it has a number of distinctions such as low latency, low jitter, the location of fog nodes at the edge of the local network, one-hop distance between the client and the server, a tremendous number of server nodes distributed geographically, the support of mobility along with real-time interactions, etc.
