In Chapter 4, Integrating Applications with JBoss Fuse, we set up a synchronous integration process between a MySQL database and a JBoss DataGrid server. Components in this scenario were closely tied to each other; indeed, if we have to shut down the DataGrid server in a maintenance operation, for example, the integration process will result in an error due to the unavailability of the DataGrid component.
This chapter discusses how to weakly couple distributed systems using the JBoss AMQ messaging platform. In the first section, readers will master the JBoss AMQ 7 architecture, and then through practical business cases, users will learn how to set up a JBoss AMQ infrastructure and how to build and run applications that rely on JBoss AMQ to share data in a safe, asynchronous, and reliable way with distributed systems.
