SERVICE ORIENTED ARCHITECTURE (SOA) FOR MANAGERS – GTAM12

Course Description

Service oriented Architecture (SOA) shows demonstrable signs of simplifying software integration. It can reduce the cost of integration significantly. The approach is not new but may be a paradigm shift for many organizations. This is analogous to e-Business, which is essentially client-server computing, but ushered many new possibilities.

This no-nonsense course is designed for the IT managers. The goal is to explain in clearly understandable terms what SOA is and how it can aid application integration. The course proceeds to cover typical development lifecycle and various roles people play in the process. The course will help the managers build a vision for future development activities.
