Abstract

A Service Oriented Architecture aims to facilitate interaction of loosely coupled services in large-scale dynamic systems. Despite a decade’s active research and development, Web Services still remain undependable (Bourne et al., 2012). In literature many proposals attempt to overcome interoperability issues, particularly typical of not-orchestrated Web Service (WS) compositions. Although these techniques aid to discover potential interoperability mismatches, they do not fit well with flexibility and dynamism, desirable characteristics e.g. in choreographies. Here unsafe run-time changes may compromise a correct execution. To support such dynamism and to mitigate the effects of such failures, we propose a flexible architecture able to realize dynamic WS compositions, supporting run-time monitoring and verification techniques. The technique we chose is a novel run-time algorithm capable to predict potential failures that can happen in near future states of a choreography. It admits an integration ”a-priori” and monitors the run-time services behaviour to provide information about possible errors when these can happen.
