For IT service providers, infrastructure construction plays a significant role in the maximization of business profits. Infrastructure design is becoming more and more crucial as IT service environments evolve from deployment on site to software as a service (SaaS), and, most recently, to cloud computing. In this paper, a cloud computing architecture is proposed from the viewpoint of business-driven IT management (BDIM); then an optimal cloud infrastructure design methodology is devised, whereby numbers of servers, routers and communication bandwidth can be calculated through considering both infrastructure costs and business losses incurred by service level agreement (SLA) violations. Finally, a complete numerical example is discussed to testify the proposed method.
