Training

In SOA, ESB patterns are used to integrate applications and businesses. The goal of this course is to explain the most common ESB patterns as well as show how to implement them in the IBM WebSphere ESB 6.2 platform. Below is a list of most key topics discussed:

• Gathering and analyzing requirements in SOA
• Service identification techniques
• How to model a message flow
• Service invocation and composition
• Content based message routing
• Audit logging
• Message filtering
• Data translation details
• Communication protocol mapping
• Messaging and asynchronous communication
• Service security patterns
• Error handling
• Transaction management

Architects and senior developers who would like to learn about the concepts behind a SOA based application integration architecture. After taking this course, students will learn how to gather requirements and analyze them. They will learn how to identify services and model message flows.

Good knowledge of Web Services (SOAP and WSDL) is required. Basic understanding of general software architecture concepts like security, messaging and transaction management is definitely recommended.

Knowledge of Java programming is optional and not required.
