Web service QOS specification in BPEL descriptions
Krasimir Baylov, Dessislava Petrova‐Antonova, Aleksandar Dimov · 2014
Service Oriented Architectures (SOA) represent a promising approach for organizations to provide their services to a large number of users, but also to consume other services in order to solve different business problems. A Service composition is useful when such problems do not have a straightforward solution. However, there may appear problems with the SLA of the composition in case of variations of QoS of its constituent services. In such a case there should exist an approach that allows for specification of QoS properties of Web-Services and their composition. This paper presents an extension of the standard WS-BPEL process description language. The implementation has a flexible design that allows both researchers and developers to tailor it for their specific needs.
