Optimization for reasonable service price in broker based cloud service environment

Cloud computing has rapidly developed with emergence of various user mobile devices. Furthermore, Cloud Service Broker (CSB) is emerged, as service mediation is willing to provide profit of a cloud customer as well as a cloud service provider in cloud environment. As a result, cloud computing nowadays has the architecture, which can provide extended services by collaboration among service providers. Even though they have the architecture for the service extension, there are no service integration technologies so far. In this paper, therefore, we introduce broker based cloud service architecture and propose an optimal pricing model to solve the service integration problem. We adopt 0-1 knapsack problem for pricing optimization in service integration, and its result shows effectiveness of our proposed pricing model.
