Virtualization and encapsulation dynamic e-business services in a service-oriented architecture

Abstract

Service Provisioning over the internet using web service specifications becomes more and more difficult as real business requirements start to shape the community. One of the most important aspects relates to dynamic service provisioning: whilst the straight forward web service usage would aim at exposing individual resources according to a fixed description, real organizations would want to expose a flexible description of their complexly aggregated products. This paper presents an approach towards reducing the technological overhead in virtual service exposition over the internet, thus allowing for more flexibility. It therefore introduces a dynamic gateway structure that acts as virtual endpoint to message transactions and can encapsulate complex business process on behalf of the provider
