Rod Fontecilla and Vicky Chang: Cloud Computing: A Transition Methodology.

Cloud Computing Conference - Cloud Slam 2009.
Abstract. Cloud computing has emerged as a new computing paradigm that gathers massive numbers of computers in centralized data centers to deliver web-based applications, application platforms, and services via a utility model. The primary difference between the service models of cloud computing and previous software (e.g., outsourcing or data center consolidation) is scale. The premise is that as the scale of the cloud infrastructure increases, the incremental time and cost of application delivery trends toward zero. Cloud computing technologies consistently include Grid Computing, Utility Computing, and Virtualization Technologies. Furthermore, cloud computing service offerings can be divided into the following areas: Cloud Strategy and Planning, Cloud Application Development, Cloud Infrastructure Services, and Cloud Security.
