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...
Information convergence system is a unified and shared information platform which aggregates different levels of resources or services to make sure students and teachers can share their knowledge freely. Architecture design is crucial to campus information convergence system. However, it is hard to eliminate information islands from different departments or management organizations. To solve this...
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...
This tutorial will take the audience through an ldquoaggregatedrdquo SOA engagement and discuss key processes, activities, and deliverables through the entire life cycle, especially in service modeling, realization, integration through an enterprise service bus and governance. Best practices and some anti-patterns will also be presented and discussed. It is mostly based on some of the speakers' pioneering...
