Tutorial number: 48
Service-Oriented Architecture (SOA) and Web Services (WS) technologies have matured into highly attractive architecture and implementation alternatives for building distributed systems. SOA concepts and Web services standards-based implementation stacks are a powerful combination that is well-suited for crafting heterogeneous B2B and EAI solutions.
In this tutorial, we introduce the fundamental concepts that define SOA as a state-of-the-art approach for enterprise application development and integration, and investigate key SOA patterns such as Enterprise Service Bus (ESB) and Business Process Choreography. Next, we explain the core stack of Web services specifications - for example, the SOAP message exchange format, the WSDL interface description language, and the UDDI service broker model. In a third module, we design and develop a complete sample application applying these concepts and technologies, making use of several code generators and runtime environments such as Apache Axis. We conclude with a discussion of the most important architectural decisions to be taken on SOA and Web services development projects - for example WSDL creation process and service interface granularity; SOAP communication style and best practices for interoperability; security, compression and other quality-of-service factors; server-side deployment and client-side invocation guidelines.
Beginner: The tutorial is targeted at practitioners with general background in software engineering and object-oriented programming; familiarity with XML and Java/C# is a plus.
