document: Cataclysm : policing extreme overloads in internet applications In this paper we present the Cataclysm server platform for handling extreme overloads in hosted Internet applications . The primary contribution of our work is to develop a low overhead , highly scalable admission control technique for Internet applications . Cataclysm provides several desirable features , such as guarantees on response time by conducting accurate size-based admission control , revenue maximization at multiple time-scales via preferential admission of important requests and dynamic capacity provisioning , and the ability to be operational even under extreme overloads . Cataclysm can transparently trade-off the accuracy of its decision making with the intensity of the workload allowing it to handle incoming rates of several tens of thousands of requests\/second . We implement a prototype Cataclysm hosting platform on a Linux cluster and demonstrate the benefits of our integrated approach using a variety of workloads .
