“…Anti-patterns are defined as common design errors that cause undesirable results. An approach based on anti-patterns for identifying performance problems and removing them is described in [11]. An OCL query is created to identify each anti-pattern and applied to the design model.…”

Abstract-Service Oriented Architecture (SOA) patterns can be applied to improve different qualities of SOA designs. The performance impact of a pattern (improvement or degradation) may affect its use, so we assess its impact by automatically generated performance models for the original design and for each candidate pattern and pattern variation. This paper proposes a technique to incrementally propagate the changes from the software to the performance model. The technique formally records the refactoring of the design model when applying a pattern, and uses this record to generate a coupled transformation of the performance model. The SOA design is modeled in UML extended with two profiles, SoaML and MARTE; the patterns are specified using Role Based Modeling and the performance model is expressed in Layered Queuing Networks. Application of the process, and pattern performance exploration, is demonstrated on a case study.

“…Model-based approaches [4,22,25] provide means for performance evaluation of the target system during an early development phase when no executable implementation is available. However, their capabilities on revealing performance problems of a target system can only be as good as the detail level of the available information about the final system.…”

Performance problems such as high response times in software applications have a significant effect on the customer's satisfaction. In enterprise applications, performance problems are frequently manifested in inefficient or unnecessary communication patterns between software components originating from poor architectural design or implementation. Due to high manual effort, thorough performance analysis is often neglected, in practice. In order to overcome this problem, automated engineering approaches are required for the detection of performance problems. In this paper, we introduce several heuristics for measurement-based detection of well-known performance anti-patterns in inter-component communications. The detection heuristics comprise load and instrumentation descriptions for performance tests as well as corresponding detection rules. We integrate these heuristics with Dynamic Spotter, a framework for automatic detection of performance problems. We evaluate our heuristics on four evaluation scenarios based on an e-commerce benchmark (TPC-W) where the heuristics detect the expected communication performance anti-patterns and pinpoint their root causes.

Early performance analysis of designs for Service Oriented Architecture (SOA) can be based on performance models derived from the design models using known techniques, such as Performance from Unified Model Analysis (PUMA). When a SOA design pattern is applied to solve some architectural, design or implementation problem, it impacts the design model and its derived performance model. Conventionally, the performance model needs to be reconstructed to reflect the design pattern changes on the design model. This thesis proposes a technique to trace the causality from the design changes introduced by the pattern application to the corresponding changes in the performance model. The approach takes as input a SOA design model expressed in UML extended with two standard profiles: SoaML for expressing SOA solutions and MARTE for performance annotations. The SOA design patterns are specified using Role Based Modeling (RBM) and the performance model is expressed in Layered Queueing Networks (LQN). To support the exploration of different patterns, the thesis proposes the following approaches: 1) Systematic identification of SOA design problem, selecting an appropriate pattern and binding the design with the RBM problem specification of the pattern; 2) Systematic recording of the SOA design changes (refactoring) using the RBM pattern solution specification; 3) Automatic derivation of the corresponding performance model changes from the design model changes using coupled transformation; 4) Automatic derivation of transformation directives from the performance model changes and annotation of the performance model with the transformation directives; 5) Automatic refactoring of the performance model by QVT model transformation. iii Systematic and automated pattern exploration techniques and the tools support developed in the thesis are illustrated and evaluated with a Browsing and Shopping SOA case study.A test suite was designed and used to verify all the major functionalities of the proposed approach. Furthermore, several design patterns are applied to the Browsing and Shopping SOA to validate their effectiveness in the process of performance analysis by a system designer.iv
