A Meta-model for context-aware adaptive Business Process as a Service in collaborative cloud environment

With the emergence of cloud computing, building and developing a new Software by SaaS composition becomes a major concern in today's cloud business. First, the business analyst establishes the Business Process (BP) of the new SaaS. Then, the SaaS composer, based on functional and non-functional requirements, discovers and selects the potential SaaS components that can fill into each of the defined tasks in the BP. Currently, enterprises need more and more flexible SaaS business process as an adaptive composite SaaS from process vendors, which interest on context changes and needs evolutions. A meta-model is proposed in this paper dealing with different concepts involved in business cloud layer. This meta-model, in which both business process and service composition are considered, is accompanied by a case study. Then, an ontology has been developed and an extract of instances has been presented to demonstrate the adaptation process. (C) 2019 The Authors. Published by Elsevier B.V.
