Dichotomy of Fog Computing in the Realm of Cloud Computing: Exploring the Emerging Dimensions

Abstract

There is much hype about the emergence of Cloud and Fog Computing in achieving a truly pervasive access to information and computing resources. Given the increased need for the instantaneous access and analysis of data with huge dimensions (big data, with respect to volume, velocity and varied formats) and the emergence of predictive analytics, individuals and businesses will experience over-reliance on Fog Computing. Despite the promise, scholars and researchers are finding it difficult to distinguish between Cloud and Fog Computing and find little time in investigating the key issues that affect these emerging computing models. In this context, the aim of this chapter is to explore the formulaic definitions and key issues surrounding Cloud and Fog Computing. Using a meta-analysis of recent literature on Cloud Computing literature and authors’ experience, this chapter presents a development projectile and emerging dimensions of computing. The chapter articulates how Fog Computing can be used at the centre of instantaneous ubiquitous data and information management which is a key requirement for competitive business entities in any given setup. At the end of the chapter, we discuss Fog Computing landscape in Africa.
