The concept of a smart city has been identified as not only representing a crucible for
technological innovation, a medium for realising global integration but also as an exemplar
response for addressing current and impending global issues (societal, environmental economic
and governance). There is now general consensus that emerging information communication
technologies (ICT) such as cloud computing can be deployed as a vehicle for catalysing smart
city innovation. There is also evidence to suggest that cloud computing has become a strategic
direction for many e-government initiatives as evidenced by the emergence of global government
clouds (G Cloud). In this paper, we delineate the concept of a smart city and explore the propitious
potential of cloud computing to enable the development of smart cities. We review the current state
of art pertaining to a selection of cloud schemes currently being operationalized by international
governments aimed at capitalising on the nascent innovation capabilities of the technological
paradigm, and present a future research roadmap for cloud facilitated smart city development.
