In our previous work, we have presented the performability manager, a distributed environment component that, using a model-based approach, realises and maintains user-requested qos. Generic modelling and monitoring techniques are inevitable for such a model-based approach. The planning of user-requested qos is done by the evaluation of automatically(More)
When reconnguring distributed systems, either because failures and/or repairs have occurred, or because the workload requirements have changed over time, an alternative connguration has to be selected, thereby taking performability and costs, i.e., quality of service, requirements into consideration. In this paper we will present the use of Markov-decision(More)
