Evaluation of Service Oriented Architectures

SOA is gradually replacing monolithic architecture as the premier design principle for new business applications. Service Oriented Architecture (SOA) is an approach for building distributed systems that deliver application functionality as a set of self-contained business-aligned services. It promises lower integration costs, increased reusability and improved enterprise agility and adaptability. The architecture evaluation will improve the problem understanding and it will clearly distinguish the strength and weakness of the architecture. It also performs the cost-benefits analysis for different alternatives and injects the reviewer's expertise into the project. In order to assess system's quality against the requirements of its customers, the architects and the developers need methods and tools to support them during the evaluation process. In this research work, an attempt has been made to investigate the possibility of evaluating the Service-Oriented Architecture employing a new quantitative evaluation method exclusively.
