JMS (Java Message Service)

Java Message Service (JMS) is a technology that allows different software applications to communicate asynchronously by sending and receiving messages. Think of it as a postal system for software: applications place messages in queues or topics, and other applications pick them up when ready. This decoupling enables reliable, scalable, and flexible communication, especially in distributed systems. JMS ensures messages are delivered even if the receiving application is temporarily unavailable, making it essential for building robust enterprise applications that need to exchange data or instructions efficiently.
