Service-Oriented Architecture (SOA) Essentials for Managers, Developers and IT Technical Staff

Course:  SOAM
Duration:  2 Days
Level:  I
Course Summary

Even though its concepts have been around for a while, Service Oriented Architecture (SOA) has recently gained strong momentum in the industry. SOA is a disciplined approach to manage the lifecycle of IT services to ensure their delivery in alignment with business strategies. It fundamentally changes the way organizations respond to changing business needs through innovation in modular architecture and service engineering practices.

The SOA Introduction for Managers, Developers and IT Technical Staff course begins with an introduction to what business process and information technology IT architecture are and what functions business process and IT architects perform.

This workshop 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.

The class 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.

The course then describes the concepts of service orientation to a business process or information technology. Components of Service Oriented Architecture are described including an Enterprise Service Bus (ESB), and service connection methods such as Extensible Markup Language (XML).

Additionally, concepts such as Component Business Modeling (CBM), Business Process Execution Language (BPEL), and Web Services Description Language (WSDL the XML-based language which provides the model for describing Web Services) are also introduced.

The reusability of services, the primary goal of SOA, emerges as a common theme through supporting sessions in SOA tools, the SOA Lifecycle, SOA Standards, and SOA Reference Architectures.

The SOA Introduction course is multi-disciplinary, which bridges between business, business management, and technology.

What You Can Expect

SOA is not just technology. Delivering the full objectives of SOA may require careful planning addressing organizational and cultural change plus new funding and ROI mechanisms, together with adoption of new architectural principles and software engineering techniques and processes.

At the end of this course, participants will be able to:

  • Describe the underlying concepts and objectives of SOA.
  • What does SOA really mean? Is it just the latest vendor hype? Will it provide real business benefit to your organization?
  • Understand what a Web Service is, and its role in a SOA.
  • Understand the practical differences between SOA and other architectures.
  • Describe the SOA development methodology (SOAD).
  • Understand how to integrate legacy applications using SOA.
  • Describe how organizations typically evolve through the stages of SOA implementation
  • Discuss when and how organizations should use the SOA approach.
Who Should Take This Course
  • 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.
