Services Computing has become an increasingly important area in the IT and business sectors. In particular, Services now account for more than half of the economy in the United States and other countries. Numerous Services Computing-related degree programs and accreditation processes are being created. However, very few systematic guidelines exist for building graduate programs for Services Computing...
In this paper, we study legacy asset reuse for SOA design. Typically, the cost of reusing legacy assets is much lower than the cost of creating new services from scratch. As an extension of our SOA service modeling, we use top-down approaches to identify business services, and use asset modeling for legacy asset identification to find potential reusable assets for those services. Using service capacity...
This paper discusses and analyzes the business process layer in the SOA solution stack (S3) model, which is also known as the SOA reference architecture (SOA-RA). Business process layer leverages the service layer to quickly compose and choreograph services and to coordinate business processes to fulfill customer requirements. Based on industry practice, we introduce a set of architectural building...
Cloud computing is evolving as a key computing platform for sharing resources that include infrastructures, software, applications, and business processes. Virtualization is a core technology for enabling cloud resource sharing. However, most existing cloud computing platforms have not formally adopted the service-oriented architecture (SOA) that would make them more flexible, extensible, and reusable...
The Service registry, the yellow pages of Service-Oriented Architecture (SOA), plays a central role in SOA-based service systems. The service registry has to be scalable to manage large number of services along with their requirements on storage and discovery. Based on our previous work on feature-based services quantification, we characterize services according to their diverse functional and non-functional...
This paper proposes a method for Web services test case generation, which is centered on a practical test data generation framework that has higher probability to penetrate the service implementation logic. This presented framework leverages both the information contained in the WSDL/XSD files and the information provided by testers as well as enables testers to customize the fields to be tested,...
Services computing has been recognized as a new foundational discipline of the modern services industry. The Technical Committee on Services Computing (TC-SVC) within IEEE Computer Society is leading an initiative to promote Services Computing Curriculum around the world. This paper defines eleven key knowledge areas in the field of Services Computing. Based on defined knowledge areas, we report 2008...
In this paper, we present a case study based services computing course delivery practice, which includes course preparation, course structure, course enablement, course evaluation and analysis, and audience-specific discussions. The case study is created based on a course offering to students from Internet business system masterpsilas program. Specifically, this paper touches the major course offering...
