A Model-Based Approach to Pragmatic Service Choreography Deployment

Abstract

International audienceThe 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
