Utility Computing Simulation |
Utility Computing (UC) misses an explicit definition of the core relation between IT resource utilisation, its total costs and service prices. Additionally, the implications of complex usage scenarios occurring in UC have not been examined for the service operations lifecycle. Missing those, UC service offers fail in: prediction of resource utilisation and dependent operational costs prediction, calculation of subsequent price scales, and subsequent runtime gross price calculations. In this paper a strategy to handle UC’s complexity proposing a simulation model to support each step in the service operations lifecycle is presented. The implementation approach for the model is based on OMNeT++. First simulation outcomes are presented.
