Multi-Phase Efficient Service Composition

There are always a number of services published or destroyed ceaselessly on the Internet, so how to make sure that the composite services are incessantly flexible, available and executed effectively has been one of the main focuses all the while. And the problem here is that the currently wide-adopted static composition pattern and the dynamic composition pattern sometimes can not give a satisfying performance in their flexibility or efficiency. So in this paper, a multi-phase lifecycle model of service composition will be presented to solve the problem mentioned above. Architecture is given to archive the multi-phase service composition model and modules are illuminated separately.
