Resource management in a cloud environment is a hard problem, due to: the scale of
modern data centers; the heterogeneity of resource types and their interdependencies; the …

Software systems dealing with distributed applications in changing environments normally
require human supervision to continue operation in all conditions. These (re-) configuring …

The emerging cloud-computing paradigm is rapidly gaining momentum as an alternative to
traditional IT (information technology). However, contemporary cloud-computing offerings …

Internet hosting centers serve multiple service sites from a common hardware base. This
paper presents the design and implementation of an architecture for resource management …

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 …

Virtualization can provide significant benefits in data centers by enabling virtual machine
migration to eliminate hotspots. We present Sandpiper, a system that automates the task of …

The growing cost of tuning and managing computer systems is leading to out-sourcing of
commercial services to hosting centers. These centers provision thousands of dense servers …

Since many Internet applications employ a multi-tier architecture, in this paper, we focus on
the problem of analytically modeling the behavior of such applications. We present a model …

In this paper we address power conservation for clusters of workstations or PCs, such as
those that support a large number of research/teaching organizations and most Internet …

Virtualization can provide significant benefits in data centers by enabling dynamic virtual
machine resizing and migration to eliminate hotspots. We present Sandpiper, a system that …
