document: Efficient resource allocation and power saving in multi-tiered systems In this paper , we present Fastrack , a parameter-free algorithm for dynamic resource provisioning that uses simple statistics to promptly distill information about changes in workload burstiness . This information , coupled with the application 's end-to-end response times and system bottleneck characteristics , guide resource allocation that shows to be very effective under a broad variety of burstiness profiles and bottleneck scenarios .
