Description
Summary:This paper presents dynamic modeling of a webserver hosted on a private cloud using grey box identification technique. In contrast to the results in literature, we model the web-server as a linear parameter varying (LPV) state space system valid around several well defined operating regions. We programmatically generate synthetic HTTP load based on open source workload tool called httperf to obtain response time as performance metric. Finally, we validate the models on test data by conducting experiments in the actual Eucalyptus cloud environment.
