Introduction With the paradigm shift experienced in information and communication technology (ICT orIT), cloud computing has emerged as a global phenomenon, spreading its wing over a widehorizon. The term ‘cloud computing’ has become a part-and-parcel of modern multinationalbusiness corporations (MNCs) such as Apple, IBM, Google, and Amazon and so on. With themonumental development of internet and computational technologies, coupled with mobiletechnologies, cloud computing has emerged as an omnipotent and omnipresent phenomena.Keeping aside the commercial intent, cloud computing has also ushered significant benefitsfor general utility, for example in healthcare sector. Therefore, the following sections willcritically discuss in detail the different modes of use and the beneficial as well as negativeoutcomes yielded by cloud computing.Conceptual frameworkFigure 1: Conceptual Framework(Source: Kavis, 20144, p.242)Defining cloud computing Kavis (2014, p.129) has defined cloud computing as delivering the computing servicesthrough the internet. In other words, cloud computing is involved in delivering on-demand3

computing resources through internet on a pay-for-use contract. Generally, the servicesprovided through cloud computing spans over a wide horizon such as servers, databases,storages, analytics, storages, software application and many more. Pearson (2013, p.18) hasmentioned core elements of cloud computing as-Pay-per-useUsing as per the nature and time of requirementThird-party provided serviceZero change in ownership of the original property (intellectual or physical)Figure 2: Core elements of cloud computing(Source: Pearson 2013, p.12)From this perspective, cloud computing can be termed as an unique service that can allowmultiple users to gain access in a specific project simultaneously without jeopardising thefunctionality or security protocols of a network infrastructure, that too irrespective ofgeographical borders or time. Exploring the evolution of cloud computing The origin of term ‘cloud computing’ is itself shrouded in cloud as there is no specificmention of this term in history. The initial schematics of cloud computing referred to the useof internet in connecting several computers and the term ‘cloud’ was used there as ametaphor for inter-connectivity irrespective of space and time (Rittinghouse and Ransome,2016, p.177). The cloud symbol was fort formally used in ARPANET in the early 1977s and4
