摘要:This paper claims that the contextual qualities of Cloud-enabled software architecture should be identified and understood in a different way by Cloud customers. The existing architectures are not designed to manipulate the contextual qualities of Cloud computing. The appearance of Cloud computing virtually forces Cloud customers to re-evaluate their application architectures in light of the Cloud computing viewpoint which requires relinquishing control over most architectural components to Cloud suppliers. In a cloud-enabled architecture, the move to possession and control over architectural components from customers to Cloud suppliers has the powerful impact on the ways Cloud customers design their Cloud architecture. In this perspective, we go beyond the traditional definition of Cloud architecture and present the concepts of architectural scope, control and design components of the architecture
