Abstract	:	Many organizations have chosen to host Internet applications at Internet DataCenters (IDCs) located near network access points of the Internet to take advantageof their high availability, large network bandwidths and low network latencies. Cur-rent IDCs provide for a dedicated and static allocation of resources to each hostedapplication. Unfortunately, workloads for these sites are highly variable, leading topoor resource-ut ilization, poor application-performance, or both. The goal of thisthesis is to develop a framework for QoS-driven dynamic resource-allocation in IDCs.Termed QUID (Quality-of-Service Infrastructure on Demand), the framework's con-tributions are threefold. First, we develop a simple adaptive algorithm to reduce theaverage number of servers used by an application while satisfying its QoS-objectives.Second, we develop an optimal off-line algorithm that bounds the advantage of anydynamic policy and provides a performance benchmark. Finally, we perform an ex-tensive simulation study using traces from large-scale Ecommerce and search-enginesites..-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
