Introduction to SOA

Overview

This course provides an introduction to the concepts of Service Oriented Architecture. This course discusses some of the key issues facing many organizations, especially dealing with integration among disparate systems. Participants will learn how SOA addresses these issues and its many other benefits.

The course also discusses related technologies such as Enterprise Service Bus and it�s relationship with SOA. The participants then look at the various SOA patterns that can be used as a basis for developing SOA applications. Participants also go through case studies to better visualize the role of SOA.

Prerequisites

No specialized technical pre-requisites are required for this course; however a basic knowledge in IT systems and distributed computing is expected.
