A Model for Dynamic Services Discovery over Largely Distributed Providers Based on QoS and Business Processes Contexts
Alexandre Perin de Souza, Ricardo J. Rabelo · 2011
This paper addresses the problem of BPM and SOA integration presenting a model of dynamic discovery of services as an approach to improve the agility of SOA-based applications. Many researches have tackled the discovery problem. However, in general they fail in discovering the most suitable service regarding business processes needs. The main contribution of this work is to offer a comprehensive, integrated, open and standard-based environment which considers functional and non-functional requirements besides business processes' contexts. The discovery acts over largely distributed service providers over the Internet (published in several UDDIs) making use of proper QoS and UBL ontologies and accessed under the SaaS model. An electronic catalog is also developed to assist the SOA designer to better capture business processes requirements and contexts.
