Abstract : Cloud computing is rapidly defining the computing paradigm for the modern networked age. Users can run their large computations online using cloud services at a fraction of the cost compared to setting up their own data centers. Clearly, cloud computing offers many advantages, and yet many large organisations including governments, the financial sector, and the health care sector are reluctant in transitioning to cloud computing. The contrail project addresses the major concerns behind this reluctance, namely mistrust in cloud platforms, the lack of Service Level Agreements (SLAs) and Quality of Protection (QoP) of data. Contrail aims at providing a federation layer support for bringing a multitude of cloud providers, both private and public, together. This will allow multi-tenancy and cloud-bursting capability to end user cloud applications while supporting SLAs and QoP agreements desired by several privacy aware sectors including governments, banks, health care providers to name a few. This chapter describes the overall architecture of the Contrail framework; from the cloud federation services to the Contrail Virtual Execution Platform (VEP) that will be closely interfaced with the IaaS layer of cloud providers. VEP upgrades the supported cloud providers and brings trust in cloud computing by adding SLAs and QoP features missing at the typical IaaS layer. The federation services interact with the provider VEPs to provide transparent access to federation resources. Furthermore, this chapter outlines challenges faced in being part of a large federation and how VEP addresses some of those.
