> ## Loosely coupled integration model

> The loosely coupled integration model is based on asynchronous messaging. There is no direct binding that connects one application to another. Some sort of intermediary process, serving as a message broker, relays information from one application to another.

> Messaging provides a great deal of flexibility from a design standpoint. The ability to communicate using standard protocols (TCP/IP, HTTP, etc.) allows for a simpler design of Integration Layer components to support the integration model.

> A loosely coupled design typically uses a set of standard messaging protocols to manage messages being sent through the message broker. All participating applications must agree on these standards.
