  • WA1650 SOA For Architects AquaLogic Edition Training and Courseware Service Oriented Architecture (SOA) shows demonstrable signs of simplifying software integration. It can reduce the cost of integration significantly and reduce time-to-market through leveraging reusable enterprise assets. Organizations are beginning to design agile business solutions following a service oriented approach. This course delves deep into various architectural aspects of SOA. It starts with Service Oriented Analysis and Design. This will help the architects understand how requirements are captured, business processes are modeled and services are identified. The curriculum then moves on to explore more advanced topics, including information architecture, transaction management and enterprise messaging architecture. Topics The course covers the following key areas of architecture: • Service and business process design. • Messaging architecture in SOA • Transaction management • Architecture governance • Best practices What you will learn Students will get to actually apply various principles in hands on exercises. This will make the concepts come alive. After taking the course, an architect will gain enough knowledge to begin devising a comprehensive architecture for a new SOA based solution. Audience IT architects, senior developers. Prerequisites Previous experience with software architecture is recommended. Some knowledge of Object Oriented Analysis and Design is required. Duration Five days.
