Message Queues & Message Brokers

Message queues enable asynchronous communication between producers and consumers by storing messages in FIFO order. They are useful for processing background tasks, distributing tasks, email services, buffering, and payment retries. Message brokers manage these queues and provide additional features like message routing, transformation, protocol translation, and support for the publish-subscribe pattern. This allows seamless integration and communication between different services in applications, such as in an e-commerce platform where order, inventory, shipping, and notification services interact efficiently.
