A shift in technological paradigm : cloud computing to fog computing

Over the years, we continue to experience changes in the field of information and technology; these changes are initiated and geared towards addressing the dynamic nature of our environment. The ubiquitous nature of mobile devices has continued to create the need to manage and control the flow and transmission of data within our environment. The technological paradigm of cloud computing was conceptualized to deal with the ever-increasing need for data storage resulting from the Internet of Things (IoT) and different mobile computing devices. Due to some shortcomings of cloud computing, Fog computing was conceptualized. The term Fog Computing in this paper is discussed to give clear assertion on the technical term, opportunities, and drawbacks
