Service Oriented Architecture Implementation

SOA is an emerging architectural style that…

·       Is business driven

·       Enhances IT’s flexibility and responsiveness to changing business needs

·       Improves a business' ability to respond to rapidly evolving  customer requirements

·       Reduces integration work for business solutions

·       Decreases the IT application maintenance workload

·       Shrinks the development workload for new applications

Early experience deploying large-scale Services-Oriented Architectures clearly demonstrates that successful enterprise-SOA implementation require far more than simply building SOAP wrappers and using WSDL to document Web Services.

SOA Implementation provides a comprehensive and realistic road map for putting the Services-Oriented Architecture promise into practice. This two-day seminar examines in detail the technical, organizational and management issues surrounding the planning and implementation of a SOA. It presents practical information and guidance that will help organizations plan the deployment of SOAs that employ internal and external Web Services to execute intra-business processes and inter-business processes.

SOA Implementation uses case studies, examples, and business language to introduce the topics and explain the choices that organizations face as they plan and build their Services-Oriented Architectures. Seminar topics include:

  • Decisions, issues and challenges concerning the implementation of business processes as applications using a Services-Oriented Architecture
  • SOA design, deployment and implementation options and alternatives
  • Best practices for implementing business processes via SOA, including major implementation phases and their component steps.

What You Will Learn 

SOA Implementation Decisions, Issues and Challenges

  • How to retrofit legacy applications as Web Services
  • How the SOA approach fits with conventional middleware
  • How to determine what business processes & services are good SOA candidates

SOA Implementation Options and Alternatives

  • How to choose your 1st SOA project
  • How to define internal intra-business processes & external inter-business processes
  • How to build an SOA implementation project plan
  • How to establish security rules via WS-Security and WS-Policy
  • How to make SOA deployment decisions
  • How to govern an SOA

How to implement business processes via SOA

  • How to design a good reusable web service
  • How to evolve an existing architecture into a Service Oriented Architecture
  • How to build a Web Service
  • How to incorporate SOAP intermediaries
  • How to build and coordinate large-scale, long-lived asynchronous processes
  • How to secure services
  • How to set policies for services
  • How to utilize evolving best practices in SOA definition, construction and deployment

Who Should Attend?

The IT and Business Area Leaders, Managers and Architects who plan and execute the SOA implementations

The technical, business analyst and business area staff who design, create and deploy SOA applications composed of Web Services

Participants in this seminar should understand the concepts and principles of Service Oriented Architecture and  Web services.
