Testing Adaptive admission control and resource allocation algorithms

In order for one to test an adaptive admission control and resource allocation algorithm, it is necessary to set up an appropriate testbed of a distributed web application like RUBiS benchmark [1], an auction site prototype modelled after eBay.com. It provides a virtualized distributed application that consists of three components, a web server, an application server, a database and its workload generator, which produces the appropriate requests. Furthermore it can be deployed in a virtualized environment using Xen server technology, which allows regulating system resources such as CPU usage and memory, and provides also a monitoring tool, Ganglia, that measures network metrics, such as round trip time and other statistics, and resource usage in virtual machines.
