OL905:  Web Services: Concepts, Implementation and Applications

Description:

Web Services are a set of standards and technologies that enable distributed application communication. They represent the next step beyond established distributed computing protocols like DCOM, RMI and CORBA. All major vendors are offering proprietary solutions to take advantage of new opportunities for Enterprise Application Integration (EAI), Business-to-Business (B2B) applications, and intra-enterprise component reuse.

OL905 is an in-depth discussion of specific technologies, an exploration of implementation issues and an overview of Service-Oriented Application (SOA) development. The course is divided into three parts.

In the first part, we study the core technologies that are used in current implementations. Specific technologies that are discussed include:

• Simple Object Access Protocol (SOAP)
• Web Services Description Language (WSDL)
• Universal Description, Discovery, and Integration (UDDI)
• Web Services Invocation Framework (WSIF)
• Web Services Inspection Language (WSIL)
• Workflows and business processes, specifically Business Process Execution Language for Web Services (BPEL4WS)
• Web Services Security (WS-Security)

The second section concentrates on services implementation with the developer in mind. Development and management issues in services-oriented architecture including interoperability, modularity, performance, reliability, scalability, and security are discussed. This section is highly flexible in that we can demonstrate a specific vendor implementation based on your institution's preference (e.g. IBM, BEA, HP, WebMethods, Microsoft .NET, Oracle or open source), or broadly survey implementations from several vendors including demonstrations of existing tools.

In the third part, we focus on development issues, diving deeply into application specific issues with hands-on lab exercises. Topics include:

• Assembling and Deploying a Web Service
• Defining and Optimizing Business Processes
• Runtime and Deployment Considerations
