On The Use Of Performance Models To Design Self-Managing Computer Systems

this paper, we describe an approach in which analytic performance models are combined with combinatorial search techniques to design controllers that run periodically (e.g., every few minutes) to determine the best possible configuration for the system given its workload. We first illustrate and motivate the ideas using a simulated multithreaded server. Then, we provide experimental results, obtained by using the techniques described here, to an actual Web server subject to a workload generated by SURG
