This paper examines service migration in a new computing paradigm, the cloud computing environment (CCE), by examining security and integration issues associated with service implementation. We postulate that a cloud architecture will evolve to be both more flexible and heterogeneous in resources because of the services complexity demanded by organizations. This introduces additional, but tractable,...
Security and privacy are two prime barriers to adoption of the cloud computing. To address this problem on Infrastructure-as-a-Service model, a trusted cloud computing platform model has been proposed to provide a closed box execution environment that guarantees confidential execution of guest virtual machines. However this model has significant drawbacks that it relies on the trusted third party...
Cloud computing has become a popular computing paradigm in which virtualized and scalable resources are consolidated to provide services over Internet. However, the resource capability of a single cloud is generally limited, and some applications often require various cloud centers over Internet to deliver services together. Therefore, a Virtual Organization (VO) will be a promising approach to integrate...
