Approaches to analyze requirements of billing management for cloud computing services

Business management using information-communication (info-communication) infrastructures such as broadband networks and data centres will become more and more important these days. Moreover, cloud computing service induces a lot of corporate alliances and it makes customer-service management complicated. Especially, billing management is very critical for both providers and customers. It is expected to establish the billing management method adjusting environment change quickly. Therefore, this paper proposes the methodology of acquiring required functions for billing management in complicated future cloud computing services. The approaches are based on the Soft Systems Methodology (SSM) with Unified Modeling Language (UML). Then the requirement functions of billing management are expressed by Use Case Diagram for future cloud computing services.
