A Message Broker is a software component that facilitates communication between different applications or systems by receiving, forwarding, and delivering messages. It acts as an intermediary, transporting messages from one application to another regardless of the type of application or its location.
The Message Broker receives messages from a sending application, temporarily stores them, and then forwards them to the respective receivers. The broker can provide various functions such as message queues, topics, message routing, and transformations to ensure that messages are transmitted efficiently and securely.
Such systems are often used in distributed application landscapes to facilitate interaction and data exchange between different applications, services, or systems by enabling loosely coupled, reliable communication.
