Towards a Multi-perspective Assessment of Scalability of Distributed IT Services

Abstract. Scalability is an important issue in distributed IT service design and should be addressed at least from technical and economic perspectives. We present a conceptual framework that addresses scalability from these two perspectives. To explore scalability of distributed services, our framework employs a value model and UML deployment model to describe scalability concerns of a distributed, commercial IT service. We illustrate our approach by a case study.
