Applying control-theoretic approaches to capacity provisioning and performance management of Web servers is gaining increasing popularity in the past several years. This paper presents a novel control-theoretic approach that is a combination of linear-parameter-varying (LPV) techniques and workload characterization using alpha-stable-model based stochastic envelopes. In particular, we parameterize...
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...
