Evaluating Performance of Software Architecture Models with the Palladio Component Model
نویسندگان
چکیده
Techniques from model-driven software development are useful to analyse the performance of a software architecture during early development stages. Design models of software models can be transformed into analytical or simulation models, which enable analyzing the response times, throughput, and resource utilization of a system before starting the implementation. This chapter provides an overview of the Palladio Component Model (PCM), a special modeling language targeted at model-driven performance predictions. The PCM is accompanied by several model transformations, which derive stochastic process algebra, queuing network models, or Java source code from a software design model. Software architects can use the results of the analytical models to evaluate the feasibility of performance requirements, identify performance bottlenecks, and support architectural design decisions quantitatively. The chapter provides

An Empirical Investigation of the Component-Based Performance Prediction Method Palladio
Model-based performance prediction methods aim at evaluating the expected response time, throughput, and resource utilization of a software system at design time, before implementation, to achieve predictability of the system’s performance characteristics. Existing performance prediction methods use monolithic, throw-away prediction models or component-based, reusable prediction models. While i...

This paper presents how the performance modeling capabilities of the Palladio-Bench are integrated into the development process of new enterprise applications based on a service-oriented architecture (SOA). The Palladio-Bench is used to predict the performance of applications early in the software development process. To better integrate the Palladio-Bench into this process, an automated transf...
متن کاملAn Empirical Investigation of the Effort of Creating Reusable, Component-Based Models for Performance Prediction
Model-based performance prediction methods aim at evaluating the expected response time, throughput, and resource utilisation of a software system at design time, before implementation. Existing performance prediction methods use monolithic, throw-away prediction models or component-based, reusable prediction models. While it is intuitively clear that the development of reusable models requires...
متن کاملA Model Transformation from the Palladio Component Model to Layered Queueing Networks
For component-based performance engineering, software component developers individually create performance specifications of their components. Software architects compose these specifications to architectural models. This enables assessing the possible fulfilment of performance requirements without the need to purchase and deploy the component implementations. Many existing performance models d...
متن کاملTowards a Modular Palladio Component Model
The Palladio Bench started out as a tool for designing and analyzing the performance of component-based enterprise software systems. Over the following years, numerous extensions have been introduced to increase Palladio’s analysis capabilities. These include in particular support for additional quality attributes. With an eye on current research projects, we expect this trend to continue. This...
