Woitsch, RobertBetz, StefanieReimer, Ulrich2017-06-212017-06-212016978-3-88579-649-7Business Process as a Service (BPaaS) is a new paradigm in Cloud Computing using domain-specific business processes as a mediator for business and IT-Cloud alignment. Therefore, business process models are extended with cloud-specific concepts. This paper introduces the modelling concepts and mechanisms to bridge the semantic distance between domain-specific business processes and IT-Cloud deployable workflows. A prototype has been developed in the H2020 project CloudSocket, where the current status of the modelling tool is available for the research community on ADOxx.org.enText/Conference Paper1617-5468
