On the support of dynamic service composition at runtime

Abstract

Network-based software application services are receiving a lot of attention in recent years, as observed in developments as Internet of Services, Software as a Service and Cloud Computing. A service-oriented computing ecosystem is being created where the end-user is having an increasingly more active role in the service creation process. However, supporting end-users in the creation of a service, at runtime, is a difficult undertaking. Users are heterogeneous, have different requirements, preferences and knowledge. Furthermore, and since we cannot assume that all users are technical experts, we conclude that highly abstract mechanisms should be available to support the service creation process. To tackle these issues and provide end-users with personalised service delivery, we claim that runtime automated service composition mechanisms are required. In this paper we present the DynamiCoS framework, which aims at supporting the different phases required to provide users with automatic service discovery, selection and composition process. In this paper we also present the developed prototype and its evaluation. © 2010 Springer-Verlag.
