Service-Enabled Automatic Framework for Testing and Tuning Multi-tier System

For a complex multi-tier system, to make the system well tuned and tested is of great challenge, since there are many configurations that can be changed in different tiers of the system. In this paper we proposed a service enabled workflow driven automatic framework for stress testing and tuning multi-tier system. In our hierarchical design, at the bottom are web service end-points following WSDM standard, in different tiers of the multi-tier system and in performance tester. On top of those endpoints are composite workflow endpoints, which together constitute the testing and tuning work-flow. The workflow is automatically iterative. The paper proposes XML schema for both performance tuning algorithms and performance best practices to allow seamless integration with the workflow. The efficiency of the proposed framework is shown in simulated experiments at the end of this paper.
