SOA Architecture and Design Principles

Overview

This course will provide each student with an overview of key concepts and issues associated with the adoption of a service-oriented architecture, including SOA principles, service design and infrastructure. It will explore the definitions and principles of each type of fundamental shared service to include presentation, business, and data services. Additionally, the course explores SOA runtime governance, service bus, service registry, security and service monitoring issues. This course trains students to apply key Service-Oriented Architecture (SOA) principles to their current SOA adoption plans, understand the scope and characteristics of SOA service infrastructure and understand the design principles associated with SOA common infrastructure and shared services.

All aspects of this class will illustrate the architecture and design of an efficient and effective SOA environment.

Prerequisites

Each student should have a basic understanding of application development either as a developer, project manager or end client.
