Web Service provides a means to integrate
functional components and for business IT solutions in
an enterprise or cross-enterprise environment.
Enterprise resources are consumed by Web Services to
provide desired capabilities expected by the users.
However, beyond service provisioning, an enterprise
needs to manage their Web services and related
resources in an optimal manner in order to maximize
the resource usage. This paper presents a framework
of Web service management aimed for solving the
resource allocation issues based on System Dynamics
models. Our approach combines the business
operational consideration and IT infrastructure
configuration. Dependency that is derived from impact
analysis of different perspectives is an essential part of
the model and can be built into control system. The
resultant system embodies the capability of autonomic
Web service management to certain degree if not fully.
The reference architecture of this framework is
accounted in this paper. We also demonstrate
dynamical behavior of the system through simulation.
