    This paper reports on the status of a project whose aim is to implement and demonstrate in a real-life environment an integrated eAuthentication and eAuthorisation framework to enable trusted collaborations and delivery of services across different organisational/governmental jurisdictions. This aim will be achieved by designing a framework with assurance of claims, trust indicators, policy enforcement mechanisms and processing under encryption to address the security and confidentiality requirements of large distributed infrastructures. The framework supports collaborative secure distributed storage, secure data processing and management in both the cloud and offline scenarios and is intended to be deployed and tested in two pilot studies in two different domains, viz, Bio-security incident management and Ambient Assisted Living (eHealth). Interim results in terms of security requirements, privacy preserving authentication, and authorisation are reported

    This keynote paper: (1) presents the 21st century vision of computing and identifies various IT paradigms promising to deliver computing as a utility; (2) defines the architecture for creating market-oriented Clouds and computing atmosphere by leveraging technologies such as virtual machines; (3) provides thoughts on market-based resource management strategies that encompass both customer-driven service management and computational risk management to sustain SLA-oriented resource allocation; (4) presents the work carried out as part of our new Cloud Computing initiative, called Cloudbus: (i) Aneka, a Platform as a Service software system containing SDK (Software Development Kit) for construction of Cloud applications and deployment on private or public Clouds, in addition to supporting market-oriented resource management; (ii) internetworking of Clouds for dynamic creation of federated computing environments for scaling of elastic applications; (iii) creation of 3rd party Cloud brokering services for building content delivery networks and e-Science applications and their deployment on capabilities of IaaS providers such as Amazon along with Grid mashups; (iv) CloudSim supporting modelling and simulation of Clouds for performance studies; (v) Energy Efficient Resource Allocation Mechanisms and Techniques for creation and management of Green Clouds; and (vi) pathways for future research.Comment: 21 pages, 6 figures, 2 tables, Conference pape

    Cross-disciplinary lessons for the future internet

    There are many societal concerns that emerge as a consequence of Future Internet (FI) research and development. A survey identified six key social and economic issues deemed most relevant to European FI projects. During a SESERV-organized workshop, experts in Future Internet technology engaged with social scientists (including economists), policy experts and other stakeholders in analyzing the socio-economic barriers and challenges that affect the Future Internet, and conversely, how the Future Internet will affect society, government, and business. The workshop aimed to bridge the gap between those who study and those who build the Internet. This chapter describes the socio-economic barriers seen by the community itself related to the Future Internet and suggests their resolution, as well as investigating how relevant the EU Digital Agenda is to Future Internet technologists

    Cloud Computing: New Business Opportunities for Telecommunications Companies?

    Get PDF
    Cloud computing has recently shifted into the center of attention of Telecommuications Companies. Deutsche Telekom, for example, just announced the importance of cloud computing as one of their leading growth sectors (Deutsche Telekom Press Release, 2010). Also other important telecommunication players such as AT&T, Vodafone and TelefĂłnica are expanding their cloud computing business. Clearly, these developments indicate that telcos believe that cloud computing provides significant business opportunities, particularly by further driving the convergence of telecommunications and information technology. Some researchers, however (cf. Greelan, 2009) state that cloud computing is nothing more than a marketing buzzword. On the other hand, Weiss (2007) mentions that although cloud computing "is a buzzword almost designed to be vague, [it] is more than just a lot of fog". In an effort to shed more light on this debate, we investigate the business opportunities of cloud computing for telecommunication companies in more detail. Thereby, we focus especially on the factors that might especially qualify telcos in becoming a significant player in this emerging domain. More specifically, our contribution is twofold: First, we indentify technical and economic factors that are relevant for the telcos' competitive position in the cloud computing market. Second, we identify future scenarios on how telcos position themselves in this market. --Cloud Computing,Telecommunications,Conjoint Analysis
