Cloud computing is penetrating into various domains and environments, from theoretical computer science to economy, from marketing hype to educational curriculum and from R&D lab to enterprise IT infrastructure. Yet, the currently developing state of cloud computing leaves several issues to address that affects cloud computing adoption across organizations. In this paper, we illustrate the state of the art of infrastructural cloud, which is essential in the decision making on cloud adoption, and highlight the challenges that can limit the scale and speed of the adoption. We then describe the cloud adoption process in an organization by showing the possible approaches and a mechanism for transforming legacy infrastructure into a virtual infrastructure-based cloud. A strategic framework for designing a high performance cloud system is also suggested to be applied when transformation into a cloud-based deployment model collides with some constraints. To show the advantage of using the framework in guiding the design of such cloud system, we provide an implementation of the framework in the design of a budget-constrained high availability cloud system.
