SUMMARY:Towards Autonomic QoS Management in Event-based an
 d Service-Oriented Environments - Samuel Kounev ( 
 Computer Laboratory\, University of Cambridge)

DESCRIPTION:The talk will present some recent work on autonomi
 c Quality-of-Service (QoS) management using online
  performance models. In the first part of the talk
 \, distributed event-based systems will be conside
 red and the issues and challenges in managing thei
 r performance and capacity will be discussed. The 
 second part of the talk will focus on dynamic serv
 ice-oriented systems looking at enterprise Grid en
 vironments as an example. We will present a novel 
 methodology for designing autonomic QoS-aware reso
 urce managers that have the capability to predict 
 the performance of the components they manage and 
 allocate resources in such a way that service leve
 l agreements are honored. Advanced features such a
 s workload characterization on-the-fly\, dynamic d
 eployment of servers on demand\, as well as dynami
 c system reconfiguration after a server failure wi
 ll be considered.
