Overview and Objectives
What is SOA? And what does SOA mean, really? Is it just the latest vendor hype? Or, will it provide real business benefit to your organization?
This one-day seminar introduces the Services-Oriented Architecture and explains both the theory and reality of this important standards-based application framework and strategy for business application agility, integration and sharing of common business processes. Seminar participants receive a comprehensive and independent overview of SOA, covering foundation concepts and facilities, as well as implementation strategies and issues.
“Understanding and Applying SOA” explains how SOA works and illustrates how the SOA approach adds business value via the deployment of shared and reusable application services in an open, platform-independent environment. 
  • What’s a Service? 
  • What’s a SOA?  How does it work and why is it different? 
  • How do organizations typically evolve through the stages of SOA implementation? 
  • When and how should organizations use the SOA approach?
The seminar defines the three typical SOA implementation phases and shows how organizations can begin with local, limited scope SOA usage and evolve to B2B Enterprise SOA, and beyond.
  • Phase 1: Mashups, data integration and wrapping Legacy code with SOA interfaces
  • Phase 2: Internal SOA using collections of shared Web Services 
  • Phase 3: External SOA for B2B process interoperability
The seminar uses non-technical language, models and graphic illustrations to explain the components of Services-Oriented Architecture:
  • What’s a Web Service? 
  • What role does XML play in SOA? 
  • What do “abstraction”, “externalization” mean, and how do they promote agility?
  • What do “loosely-coupled” and “cohesion” mean and how do they promote agility? 
  • What are WSDL and SOAP, and how do they work together? 
  • What’s Coordination? Choreography? Orchestration? How do they work? 
  • What’s an Enterprise Service Bus? What does it do? When do you need one?
Who Should Attend?
This seminar will meet the needs of two groups of two groups of learners:
  • For leaders and technical staff in IT and the business areas who need "SOA Literacy", this seminar provides a concise primer in SOA concepts, facilities, issues and terminology. 
  • For the leaders, technical staff, business analysts and business area staff who will design and create SOA applications composed of Web Services, this seminar will serve as "SOA 101", building a solid conceptual foundation for more advanced skills-building classes in J2EE Web Services, C# Web Services, Service-Oriented Analysis & Design (SOAD) Business Process Modeling, Business Process Execution Language (BPEL), etc.
Recommended participants include:
  • IT and business area leaders who plan and influence application architectures and strategies 
  • IT and business area staff who will design SOA applications and Web Services 
  • Developers and Project Leaders who will build and implement SOA applications and Web Services
What You Will Learn
What is SOA?

  • What makes a shareable and reusable Web Service different? 
  • How do transactions aggregate into Web Services and choreographed business processes?
When and why would you use SOA?
  • What are the typical SOA implementation stages? 
  • How does SOA support application flexibility, agility, scalability and quality? 
  • What business scenarios are best for the SOA approach? 
  • How does SOA help you address platform and application integration?
How do you build a Services-Oriented Architecture?
  • How do Web Services work? 
  • What makes “loosely-coupled” so good and “tightly-coupled” so bad? 
  • What open standards does SOA rely on? Is there more than SOAP and WSDL? 
  • What’s a Service Contract Language and why are they needed?
What’s an Enterprise Service Bus (ESB)?
