In this work, we investigate mechanisms to ensure that a shared data center can operate within a power budget, while optimizing a global objective function(e.g., maximize the overall revenue earned by the provider). We present the BrownMap methodology that is able to ensure that data centers can deal both with outages that reduce the available power or with surges in workload. BrownMap uses aut...

Data centers have become indispensable infrastructure for data storage and facilitating the development of diversified network services and applications offered by the cloud. Rapid development of these applications and services imposes various resource demands that results in increased energy consumption. This necessitates the development of efficient energy management techniques in data center...
