Overview

The pervasiveness of social network platforms (e.g. Facebook) has profoundly changed how humankind communicates and interacts today, e.g. in virtual platforms and communities, but also to represent, document and explore inter-personal relationships digitally. In parallel, our capabilities and resources are dramatically increasing and mean that many Internet connected users have significant resource endowments that are underutilised. Volunteering computing has taught us that at the edges of the Internet resource owners are willing to make their resources available for “good uses” altruistically. Consider that the average Facebook user has 130 friends, and immediately a large connected network of resources based upon social relationships begins to present itself.

Social Clouds are defined asresource and service sharing frameworks that utilize relationships established between members of a social network to address these observations. They provide an environment in which (new) provisioning scenarios can be established based upon implicit levels of trust that transcend from inter-personal relationships digitally encoded within social network platforms. Their vision is motivated by the need of individuals or groups for specific resources or capabilities that could be made available by connected peers and peer groups. In simple words: Social Clouds use social networks as mechanisms for efficient collaboration, as users leverage their existing networks to share capabilities and resources. Such resources are not necessarily only computational resources, but can be any electronically consumable service, including human resources, skills and capabilities.

To address the many research challenges in this domain an interdisciplinary approach is essential. The Social Cloud research agenda therefore leverages methods and expertise in the broad areas of Computer Science, Economics and Sociology.

abstract = {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 their own services,
resources and data via social networks. To substantiate this, we present a Social
Compute Cloud where the provisioning of Cloud infrastructure occurs through
``friend''

relationships. In a Social Compute Cloud, resource owners offer virtualized
containers on their personal computer(s) or smart device(s) to their social
network. However, as users may have complex preference structures concerning
with whom they do or do not wish to share their resources, we investigate, via
simulation, how resources can be effectively allocated within a social community
offering resources on a best effort basis. In the assessment of social resource
allocation, we consider welfare, allocation fairness, and algorithmic runtime.
The key findings of this work illustrate how social networks can be leveraged
in the construction of cloud computing infrastructures and how resources can
be allocated in the presence of user sharing preferences.}}

abstract = {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.}}
