Advanced Message Queuing Protocol

The Advanced Message Queuing Protocol (AMQP) is a standardized method for sending messages between different software applications, ensuring reliable and secure communication. Think of it as a delivery service: applications send messages to a queue, like a mailbox, and other applications retrieve those messages when ready. AMQP handles message routing, delivery confirmation, and ensures that messages aren't lost, even if the recipient isn’t available immediately. It's widely used in systems where reliable data transfer and coordination between distributed components are critical, such as financial systems, online services, and cloud applications.
