With the growing availability of software applications as web services, web service composition is an emerging paradigm for enabling application integration within and across organizational boundaries. This paper presents a novel approach to partition a composite web service written as a BPEL program into a equivalent set of decentralized processes and deploy them into a predicable intranet based web servers cluster. It gives a revised genetic algorithm to partition a BPEL program represented as a program dependence graph and generate an optimized execution setup under a managed web servers cluster, with the goal of minimizing execution time of the process. Some empirical experiments and evaluations show and prove the efficiency of our approach.
