Framework for Dynamic Web Services Composition Guided by Live Testing

Web services allow businesses to offer their services and consumers to retrieve and use them. Businesses own some services and can reuse services that belong to other businesses to perform new transactional activities. By doing this, they achieve outsourcing, cost, and resources optimization. The advances in design principles, architectures, protocols and languages have helped to solve some of the problems related to the composition of business applications. Web service composition technology emerged as a new approach for efficient automation and integration of business processes based on Service-Oriented Architecture (SOA). SOA provides a set of principles to create distributed computing systems that support the creation of loosely coupled applications in heterogeneous and distributed environment. Service computing or engineering covers the entire lifecycle of services that include: modeling, creation, realization, deployment, publication, discovery, composition, delivery, collaboration, monitoring, adaptation, optimization, and management. In this paper we propose an architecture for dynamic composition of web services that is guided by live testing technique. The main focus is on the framework and composition requirements.
