In this chapter, we covered a lot of areas related to the integration of the RabbitMQ message broker with other types of system. The Spring AMQP and Spring integration frameworks were introduced as layers of abstraction on top of the RabbitMQ Java client libraries. Demonstrations on the use of RabbitMQ with the Mule and WSO2 ESBs were introduced following the pattern that we implemented using the Spring integration framework. We discussed how to integrate different types of database directly with the message broker and what types of adapter for other protocols the RabbitMQ broker provides. In the end, we saw how different provisioning tools provide support for RabbitMQ so that it can be deployed in a purely automated manner and how to test applications using the broker.
