  • This paper presents a control-theoretic approach to performance management of Internet Web servers to meet Service Level Agreements (SLA). In particular, a CPU frequency management problem is studied to provide response time guarantees with minimal energy cost. A linear uncertain model and a linear-parameter-varying (LPV) system are derived based on first-principles analysis of transient and steady-state queueing dynamics from the allocated CPU resource to request response time. The LPV… CONTINUE READING
