Data centers are known to consume substantial amounts of energy. A large portion of the energy supply is used to power the servers that provide infor-mation processing and storage capability. However, the number and capacity of these servers is usually designed to handle workload during peak traffic, which leads to poor utilization of servers and wastes energy during off-peak demand periods. Although servers can be switched off during low demand periods to save energy, switching them back on takes time and may hurt the response time of the system. This dissertation explores dynamic control policies that enable energy savings without compromising performance.
