Resilient Web Services for Timeless Business Processes

ABSTRACT

Many business and scientific processes make extensive use of service-oriented architectures, using distributed services. These are often provided by third parties and are thus not under direct control of process owners. In this paper we discuss the issues of ensuring continuous and faithful execution of processes in distributed environments, focusing specifically on Web Services. Recently, we introduced a specification of Resilient Web Services, that makes current Web Services more robust, and a framework for the monitoring of Web Services, that allows detecting anomalies. In this paper, we describe alternative implementations of the framework for monitoring of Web Services. We also present possible approaches easing the deployment of Resilient Web Services: a framework consisting of tools deployable at the Web Service operator site enabling easy transformation of a regular Web Service into a Resilient Web Service, and a registry with notifications that decorates existing Web Services with resilient methods.
