HIGHLIGHT Open-Source ESBs in Action shows how to implement an Enterprise Service Bus (a key SOA concept) using the popular open-source technologies Mule and ServiceMix. DESCRIPTION An Enterprise Service Bus, or ESB, is a piece of software that integrates enterprise applications without requiring the developer to write custom code. Open Source ESB = Free ESB. This is very good for an enterprise developer. And it's an increasingly popular approach--Mule alone has seen over 1 million downloads. Open-Source ESBs in Action is an example-driven guide for Java developers implementing an ESB using the open-source software Mule and ServiceMix. The authors present real-world scenarios and show how these free tools can save both development time and tens of thousands of dollars in software cost. The book explores the key features of an ESB, such as transformation, routing, security, connectivity. The book also describes how to solve common enterprise integration problems using a structured approach. KEY SELLING POINTS * Deep coverage of Mule and ServiceMix * Reusable code examples * Practical coverage of common usage scenarios MARKET INFORMATION This book bases its examples on two open-source implementations, Mule and ServiceMix, which have combined downloads of well over 1 million. 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.
