Service provision in a utility computing environment |
This project is motivated by the gap between technology-centred service provisioning frameworks and the business model Utility Computing. In the beginning this paper introduces the term ‘Utility Computing’ [UC] as an on-demand service provision business model for Service-oriented Architectures. It distinguishes Utility Computing from technology-originated terms such as Grid or J2EE.

The paper describes these technologies as possible frameworks to implement IT architectures for UC business models. And it determines that actual frameworks are not smart enough to fit the service provisioning demands of small to medium-sized businesses. Therefore a technology-independent and UC-conform service provisioning model is claimed, that enables framework evaluations and simulations of provisioning demands.
Subsequently, the basic structure for a technology-independent, UC-conform service provisioning model is described. As a first step towards such a model this paper introduces the general conditions for such a network, underlying use cases, derived network elements and appropriate workflows. With this as base the overall project aims to provide a technology-abstracted model for service provision and fundamentals for load characteristic simulations for UC environments.
