Message Broker

A message broker is like a central communication hub that helps different computer systems or applications exchange information efficiently. It receives messages from one part of the system, processes or organizes them if needed, and then directs them to the appropriate destination. This setup allows diverse applications to communicate asynchronously and reliably without being directly connected. Think of it as a postal office: it collects, sorts, and delivers messages to the right recipients, ensuring smooth data flow across complex systems. Message brokers improve scalability, flexibility, and fault tolerance in software architectures.
