ABSTRACT
In this paper, we extend our previous work on committing service instances to the applications in a service-oriented environment, and we propose a distributed heuristic algo- rithm which is able to estimate the number of future service instances needed by each application instance in a future time. Also, this algorithm does not assume any specific type of distribution function for services execution time and ap- plications interarrival time. In this paper, after presenting the mathematical basis for the proposed distributed algo- rithm, we explain how this algorithm can be implemented in a distributed environment, and through the simulations and performance comparisons, we show that the proposed algorithm improves the performance of the system signifi- cantly, compared to a No Commitment Policy System and a Full Commitment Policy system.
