A Survey of Cloud Computing and Social Networks <s> Introduction <s> Social networks are playing an important role in personal as well as corporate environments. However, perceived issues and evolving challenges may hinder further expansion of social networks to meet new opportunities. In this paper, we review inherent concepts and properties of social networks and highlight major analytical evaluation criteria, which are used to identify key findings that reveal degrees of benefits and shortcomings of social networks. We also discuss some proposed solutions related to decentralized social networks in the context of business implications as well as their effects on privacy, identity and trust issues. Future perspectives of social networks are also envisioned in this paper. <s> BIB001 </s> A Survey of Cloud Computing and Social Networks <s> Introduction <s> With the increasingly ubiquitous nature of Social networks and Cloud computing, users are starting to explore new ways to interact with, and exploit these developing paradigms. Social networks are used to reflect real world relationships that allow users to share information and form connections between one another, essentially creating dynamic Virtual Organizations. We propose leveraging the pre-established trust formed through friend relationships within a Social network to form a dynamic“Social Cloud”, enabling friends to share resources within the context of a Social network. We believe that combining trust relationships with suitable incentive mechanisms (through financial payments or bartering) could provide much more sustainable resource sharing mechanisms. This paper outlines our vision of, and experiences with, creating a Social Storage Cloud, looking specifically at possible market mechanisms that could be used to create a dynamic Cloud infrastructure in a Social network environment. <s> BIB002 </s> A Survey of Cloud Computing and Social Networks <s> Introduction <s> We present a Systematic Literature Review (SLR) on Cloud Computing that selected 39 papers from first tier journals and conferences in the period 2008-2012. The selective approach captures the relevant points of view on Cloud Computing, namely the overall paradigm in terms of delivery and deployment. Afterwards, we point out the technological issues about networking and data management in Cloud Computing. This SLR extends previous reviews thanks to a longer time period and a wider research sample. <s> BIB003
A social network is a structure of entities interconnected through a variety of relations. These entities are typically referred to as "users". The relationships between these users have a number of different names across different social networks such as friends, or followers. Through these relationships users share messages and media amongst themselves. There exist a number of online social networking websites such as the popular Facebook, LinkedIn and Twitter. These social networking sites have well over 100 million active members. With such a great number of users using these services, social networks present an interesting area of study in a variety of ways BIB001 . Cloud computing refers to the access of computing resources across a network. These resources include but are not limited to networks, storage, servers and services. This model can provide a number of advantages. Chief among them is the reduction of costs. An organization can utilize cloud computing services from some third party when such resources are required and scale up and down as needed without needing to invest in costly infrastructure. Another major benefit is that applications and data can be accessible at any time through the Internet BIB003 . Cloud computing and social networking has intermingled in a variety of ways. Most obviously social networks can be hosted on cloud platforms or have scalable applications within the social networks. Recent research has also proposed cloud based applications using social networks for user management and authentication in a system called social clouds BIB002 . In this paper, we examine the trends and issues in cloud computing and social networking. The paper is organized as followed: Section 2 briefly reviews social networks and cloud computing, Section 3 describes the current applications and uses of both social networks and cloud computing, Section 4 examines the cloud architecture that is being employed, Section 5 reviews current applications, and Section 6 concludes the paper.
