Designing Decentralized Service Compositions: Challenges and Solutions

Abstract

Abstract. This paper reports a new approach to the decentralized execution of service compositions. The motivation of our work is to provide a systematic solution for the advanced configuration of P2P service interactions when they are involved in a composition. In order to do so, we consider a service composition as a centralized workflow specification and derive corresponding cooperating process in a such way that the dependencies of the centralized specification are implemented as P2P interactions between underlying services that execute the derived processes. More precisely, we present the most important issues of deriving operation and propose corresponding solutions that run counter to naive intuition.
