Today, software engineering is challenged to handle more and more large-scale distributed systems with a guaranteed level of service quality. Component-based architectures have been established to build more structured and manageable software systems. However, due to time and cost constraints, it is not feasible to use a trial and error approach to ensure that an architecture meets the quality of service (QoS) requirements. In this tool demo, we present the Palladio Workbench that permits the modeling of component-based software architectures and the prediction of its quality characteristics (e.g., response time and utilization). Additional to a general tool overview, we will give some insights about a new feature to analyze the impact of event-driven communication that was added in the latest release of the Palladio Component Model (PCM).
