Seminar: Building SOA with Web Services

Seminar on Building Service-Oriented Architectures
with Web Services by Olaf Zimmermann

Service-Oriented Architecture (SOA) concepts and Web services technologies have matured into highly attractive architecture and implementation alternatives for building distributed systems. SOA concepts and Internet protocol-based implementation stacks are a powerful combination that is well-suited for crafting heterogeneous business-to-business and enterprise application integration solutions.

In this seminar, we introduce SOA as an architectural style defined by patterns such as Enterprise Service Bus (ESB) and service composition. We present two industry case studies that demonstrate where and how these patterns can be applied in practice. Next, we present selected elements of the Web services technology standards stack from an application programmer`s perspective, for example SOAP and WSDL.

In a third module, we design and develop a complete sample application applying the introduced concepts and technologies, making use of the Web services editors and code generators in the Eclipse Web Tools Project (WTP).  We conclude with a discussion of the key architectural decisions on SOA and Web services development projects – for example REST vs. SOAP message exchange; service interface creation process and granularity concerns; security, reliability and other quality-of-service factors; server-side deployment and client-side invocation guidelines. This discussion centers around the lessons learned on large-scale industry case studies.
