When independent applications have to exchange information with one another, this is called enterprise integration. For example, the CRM application has to know about the order history of a customer that is stored in the sales application. A technology that is often used to integrate these applications is called an enterprise service bus (ESB). There are many different ESB implementations, both commercial as well as open-source.

Open-Source ESBs in Action describes two open-source ESB implementations: Mule and ServiceMix. The authors present a practical approach on how to use ServiceMix and Mule and present examples of how to use ESBs in real-world scenarios. You will learn how the various features of an ESB such as transformation, routing, security, connectivity, and more can be implemented using these two ESBs. You will also learn how to solve common enterprise integration problems using a structured approach.

Working in integration projects is exciting, with new technologies and paradigms arriving every day. In this area, open source is playing a more and more dominant role with projects such as Mule and ServiceMix. Open-Source ESBs in Action will help you to learn open-source integration technologies quickly and will provide you with knowledge that you can use to effectively work with Mule and ServiceMix.
