Building a Performance Model of Streaming Media Applications in Utility Data Center Environment
Overview Utility Data Center (UDC) provides a flexible, cost- effective infrastructure to support the hosting of applications for Internet services. In order to enable the design of a "utility-aware" streaming media service which automatically requests the necessary resources from UDC infrastructure, this papers introduces a set of benchmarks for measuring the basic capacities of streaming media systems. The benchmarks allow one to derive the scaling rules of server capacity for delivering media files which are encoded at different bit rates and streamed from memory vs disk. Using an experimental testbed shows that these scaling rules are non-trivial. This paper develops a workload-aware, media server performance model which is based on a cost function derived from the set of basic benchmark measurements. It validates this performance model by comparing the predicted and measured media server capacities for a set of synthetic workloads.
