This chapter introduces different types of channels used in a messaging system, their behaviors, and how each of them can be simulated using WSO2 ESB.
How the caller can be sure that exactly one receiver will receive the document or perform the call.
How the sender broadcasts an event to all interested receivers.
How the application sends a data item such that the receiver will know how to process it.
How a messaging receiver gracefully handles a message that makes no sense.
What the messaging system does with a message it cannot deliver.
How the sender ensures delivery of a message, even if the messaging system fails.
How to connect an application to the messaging system to send/receive messages.
How multiple messaging systems can be connected so that messages available on one are also available on the others.
An architecture enabling separate applications to work together in a decoupled fashion such that applications can be easily added or removed without affecting the others.
