Preface Successfully implementing an SOA requires applications and infrastructure that can support the SOA principles. Applications can be enabled by creating service interfaces to existing or new functions hosted by the applications. The service interfaces should be accessed using an infrastructure that can route and transport service requests to the correct service provider. As organizations expose more and more functions as services, it is vitally important that this infrastructure should support the management of SOA on an enterprise scale. This IBM® Redbook looks at how the IBM messaging products support an SOA environment. In particular, it will look at WebSphere® Application Server, WebSphere Enterprise Service Bus, WebSphere MQ, and WebSphere Message Broker in an SOA environment. It discusses how they support SOA, compare the potential ESB product implementations, and show examples of building the infrastructure and creating mediations. The team that wrote this redbook
