A Performance Model Management Repository Based on the Palladio Component Model

Applying performance models to evaluate component-based enterprise applications in practice is becoming more and more difficult with an increasing organizational complexity. Components can be governed by different organizational units, are subject to a continuous shift between life cycle phases, and exhibit diverging release levels. Creating and maintaining performance models based on the composition of these components can, therefore, represent an elaborate task. A Performance Model Management Repository (PMMR) supports managing performance models in complex enterprise environments. This paper presents the implementation of a PMMR based on the Palladio Component Model (PCM). The PCM meta-model is extended to enable managing and maintaining multiple versions of components and their interfaces. Furthermore, resource demand specifications derived from different hardware environments are integrated into the meta-model. The Palladio-Bench is extended for persisting PMMR elements to EMFStore.
