A model-based approach for the pragmatic deployment of service choreographies

Abstract

The development of applications using service choreographies is becoming one of the de facto standards for the Future Internet. However QoS-aware management of service compositions is usually performed without considering service sharing. This simplifying assumption makes choreography deployment less feasible in real scenarios, in which a single service is typically shared in many scenarios. In this paper we discuss the problem of managing multiple choreographies in multi-cloud environments and we advocate that sharing-aware deployment is a more effective and resource-efficient approach. We propose a model for the combined deployment of multiple choreographies on top of a shared set of services, and we further investigate the problem through experiments.
