This Redpaper shows how to build an Enterprise Service Bus (ESB) using current IBM technology. The paper is based on a simple application scenario in which Web services invocations are used to implement a simplified supply chain process for a consumer electronics retailer. We add an ESB into the scenario between the service consumers and service providers, which provides greater flexibility and loose coupling. We explore design considerations for an ESB in a service-oriented architecture (SOA) and implement the Broker design pattern for this decoupling. We use WebSphere Business Integration Message Broker V5 to implement the ESB with services hosted on WebSphere Application Server.
This Redpaper is divided into three sections:
- Design guidelines
- Development guidelines
- Runtime guidelines
This paper is an extension of the IBM Redbooks publication Patterns: Implementing an SOA Using an Enterprise Service Bus, SG24-6346.
