Title Predicting service metrics using real-time analytics
Speaker Rolf Stadler (KTH Royal Institute of Technology, Sweden)
Abstract Predicting the performance of cloud services is intrinsically hard. In this work, we pursue an approach based upon statistical learning, whereby the behavior of a system is learned from observations. Specifically, our testbed implementation collects device statistics from a server cluster and uses regression to accurately predict, in real-time, client-side service metrics for a video streaming service and a key-value store running on the cluster. The method is service-agnostic in the sense that it takes as input operating-systems statistics instead of service-level metrics. We show that feature set reduction improves prediction accuracy, while simultaneously reducing model computation time. We discuss design and implementation of a real-time analytics engine, which processes streams of device statistics and service metrics from testbed sensors and produces model predictions through online learning. This work is an ongoing collaboration with Ericsson Research.
