It has recently been proposed that Internet energy costs, both monetary and environmental,
can be reduced by exploiting temporal variations and shifting processing to data centers …

This paper studies the online optimal control problem with time-varying convex stage costs
for a time-invariant linear dynamical system, where a finite lookahead window of accurate …

Data centers and their applications are exponentially growing. Consequently, their energy
consumption and environmental impacts have also become increasingly more important …

One of the most important goals of data-center management is to reduce cost through
efficient use of resources. Virtualization techniques provide the opportunity of carving …

Feedback control is central to managing computing systems and data networks.
Unfortunately, computing practitioners typically approach the design of feedback control in …

Data centers, as resource providers, are expected to deliver on performance guarantees
while optimizing resource utilization to reduce cost. Virtualization techniques provide the …

Both power and performance are important concerns for enterprise data centers. While
various management strategies have been developed to effectively reduce server power …

In the past, enterprise resource planning systems were designed as monolithic software
systems running on centralized mainframes. Today, these systems are (re-) designed as a …

Elasticity is the key feature of cloud computing technology, which can automatically reduce
and add resources to meet users' need. In order to achieve elasticity, we should find how …

A wide variety of software systems employ closed loops (feedback) to achieve service level
objectives and to optimize resource usage. Control theory provides a systematic approach to …
