Modeling and non-functional analysis of service-oriented architectures using AADL

Nowadays, service-oriented architectures (SoA) are increasingly used to develop dynamic enterprise systems. Due to the increasing need for high quality services, it is desirable to consider different qualitative aspects in this architecture (for example security, availability, reliability, fault tolerance, etc.). As architecture analysis and design language (AADL) can be used in the analysis of partially defined architectural patterns with limited architectural details, it is suitable for specifying large-scale complex systems. In this paper, we present a formal approach to model functional and non-functional aspects in service oriented applications through AADL language. We will explain how different parts of SoA can be specified through AADL and how different non-functional aspects can be analyzed using the proper existing tools for AADL.   Key words: service-oriented architectures, architecture analysis and design language, analysis, non-functional aspects.
