Abstract

Changeable requirements for modern services, provided in global environment, and their constant reengineering demand dynamic composition of services which is able to estimate changes of various parameters, both functional and non-functional ones. Web Services Agreement is a convenient way to contain QoS parameters, but state-of-the-art SLA-aware methods are not able to support all classes of nonfunctional parameters and provide runtime support and dynamic reconfiguration at the same time. This paper provides a novel SLA-aware dynamic Web Services Composition Approach that allows performing such composition.
