Performance Management in Dynamic Computing Environments

In this paper we argue that the traditional approach to performance analysis needs to be revisited to be applicable in modern computing environments. The major reasons are the highly dynamic and changing QoS requirements, which require fast and proactive performance tuning activities and the interdependencies between user behaviour and system performance, which must be adequately covered in the workload modelling process. We argue for a paradigm shift towards performance management and will discuss the impacts on workload modelling and on performance analysis. Some initial results towards a performance management approach will be presented.
