—Online relationships in social networks are often based on real world relationships and can therefore be used to infer a level of trust between users. We propose leveraging these relationships to form a dynamic " Social Cloud, " thereby enabling users to share heterogeneous resources within the context of a social network. In addition, the inherent(More)
—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(More)
—Currently, the Cloud landscape is a fragmented, static and shapeless market that hinders the paradigm's ability to fulfil its promise of ubiquitous computing on tap and as a commodity. In this paper, we present our vision of an autonomic self-aware Cloud market platform, and argue that autonomic market platforms for Clouds can step up to the challenge of(More)
—Social network platforms have rapidly changed the way that people communicate and interact. They have enabled the establishment of, and participation in, digital communities as well as the representation, documentation and exploration of social relationships. We believe that as 'apps' become more sophisticated, it will become easier for users to share(More)
—In this paper, we lay the foundations for a contextu-alisation of trust, the role it plays, and its different layers within the context of a novel paradigm: Social Cloud Computing. In a Social Cloud, trust plays a vital role as a collaboration enabler. However, trust is not trivial to define, observe, represent and analyse as precursors to understand(More)
Social Cloud Computing is an emerging online collaboration paradigm which is characteristic of many socially oriented electronic platforms. The operation of such a platform requires computational infrastructure to facilitate the platform itself as well as the services enabling its basic operation. While this infrastructure currently requires(More)
One of the major challenges facing the Cloud paradigm is the emergence of suitable economic platforms for the trading of Cloud services. Today, many researchers investigate how specific Cloud market platforms can be conceived and in some cases implemented. However , such endeavours consider only specific types of actors, business models, or Cloud(More)
