Service availability and QoS, in terms of customer affecting performance metrics, is crucial for service systems. However, the increasing complexity in distributed service systems introduce hidden space for software faults, which undermine system availability, leading to fault or even down time. In this paper, we introduce a composition technique, Coordinated Selective Rejuvenation, to automate the...
Locating and diagnosing performance faults in distributed systems is crucial but challenging. Distributed systems are increasingly complex, full of various correlation and dependency, and exhibit dramatic dynamics. All these made traditional approaches prone to high false alarms. In this paper, we propose a novel system modeling technique, which encodes component's dynamic dependencies and behavior...
