Social Cloud: Concept, Current Trends and Future Scope

In recent years, the idea of Social Cloud has been coming to the forefront of research. Social Cloud is a metaphor of collaborative resource sharing framework on online Social network. The central theme of Social Cloud is to utilize computational resources on the basis of ‘give-and-take’ policy for mutual benefit. By keeping Social Cloud is a collaborative resource sharing framework and as a center point, researchers visualize Social Cloud from various perspective. The series of reported views regarding Social Cloud, on the one hand, shows its potential to act as a unique computing, on the other hand, makes the overall picture confusing. Moreover, research and development on Social Cloud is currently at its infancy, with many issues still to be addressed. In this paper, we present a survey on Social Cloud, highlighting its key concept, current trends as well as research challenges. The aim of our work is to provide a better understanding of the theoretical challenges of Social Cloud. 1 Social Cloud Computing paradigm has seen a massive shift in last few years. This gradual shift in computing paradigm is essentially to address the different needs of the hour. Distributed computing concep
