Abstract

In this paper, we present a framework that allows us to orchestrate web services such that the web services involved in this orchestration interact properly. To achieve this, we predefine service interfaces and certain routing constructs. Furthermore, we define a number of rules to incrementally compute the price of such a properly interacting orchestration (i.e. a web service) from the price of its web services. The fact that a web service gets only payed after its service is delivered (no-cure-no-pay) is reflected by considering a probability of success. To determine a safe price that includes the risk a web service takes, we consider the variance of costs.
