This talk shows how operators of Internet-scale distributed systems, such as Google, Microsoft, and Akamai can reduce electricity costs (but not necessarily energy consumption) by dynamically allocating work among
data centers in response to fluctuating energy prices. The approach applies to systems consisting of fully replicated clusters of servers installed in diverse geographical locations where energy can be purchased through spot markets.
Using historical energy prices for major energy markets in the United States, as well as usage data from Akamai’s content delivery network, we should how much can be saved now, and what might be saved in the future given server technology trends.

Joint work with Asfandyar Qureshi, Rick Weber, Hari Balakrishnan, and John Guttag.
