HornetQ

HornetQ is a messaging system that allows different parts of a computer application or system to communicate efficiently. Think of it as a postal service within a computer, where messages are sent and received reliably, even if some parts are busy or temporarily unavailable. It manages the delivery, storage, and routing of messages, ensuring that information gets to the right place at the right time. Used in enterprise environments, HornetQ helps systems coordinate tasks, process data asynchronously, and improve overall performance by decoupling components for better scalability and resilience.
