Service-Oriented Architectures fo Enterprise Scale Systems

Overview
The course combines intensive seminar presentations with small group discussion workshops
The course covers SOA and the underlying web service technologies typically used in the deployment of SOA systems. A key part of the course is that covering the analysis and design of SOA systems. Security issues are also discussed. As befits an architect and analyst oriented course the following important areas are also explored

• Risk and cost-benefit analysis
• Staff training
• Governance
• Testing and quality control
