This is the first practical treatment of the design and application of feedback control of
computing systems. MATLAB files for the solution of problems and case studies accompany the …

A Google cluster is a set of machines, packed into racks, and connected by a high-bandwidth
cluster network. A cell is a set of machines, typically all in a single cluster, that share a …

The advent of cloud computing promises highly available, efficient, and flexible computing
services for applications such as web search, email, voice over IP, and web search alerts. Our …

Periodic behavior is common in real-world applications. However in many cases, periodicities
are partial in that they are present only intermittently. The authors study such intermittent …

Large-scale online service providers have been increasingly relying on geographically
distributed cloud infrastructures for service hosting and delivery. In this context, a key challenge …

Data centers have recently gained significant popularity as a cost-effective platform for hosting
large-scale service applications. While large data centers enjoy economies of scale by …

Data centers consume tremendous amounts of energy in terms of power distribution and
cooling. Dynamic capacity provisioning is a promising approach for reducing energy …

Evaluating the performance of large compute clusters requires benchmarks with representative
workloads. At Google, performance benchmarks are used to obtain performance metrics …

Policy-based management provides a means for IT systems to operate according to
business needs. Unfortunately, there is often an "impedance mismatch" between the policies …

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