The talk will present some recent work on autonomic Quality-of-Service (QoS) management using online performance models. In the first part of the talk, distributed event-based systems will be considered and the issues and challenges in managing their performance and capacity will be discussed. The second part of the talk will focus on dynamic service-oriented systems looking at enterprise Grid environments as an example. We will present a novel methodology for designing autonomic QoS-aware resource managers that have the capability to predict the performance of the components they manage and allocate resources in such a way that service level agreements are honored. Advanced features such as workload characterization on-the-fly, dynamic deployment of servers on demand, as well as dynamic system reconfiguration after a server failure will be considered.
