Balancing a data center’s reliability, cost, and carbon emissions is challenging. For instance, data centers designed for high availability require a continuous flow of power to keep servers powered on, and must limit their use of clean, but intermittent, renewable energy sources. In this paper, we present Yank, which uses a transient server abstraction to maintain server availability, while allowing data centers to “pull the plug” if power becomes unavailable.
