Performance guarantees via pole placement for a webserver hosted on a private cloud

In this paper we apply pole placement techniques to meet the performance objectives of a web server hosted on a private cloud. The web server is modeled as a switched system with models developed for several well defined operating regions using system identification technique. We then obtain the conditions for placement of exact and regional poles in desired locations using full state feedback to guarentee performance and stability. The experiments are performed on the open source Eucalyptus based cloud setup.
