Message Queues

A message queue is a communication mechanism used in software systems where messages are stored temporarily in a queue until they are processed. Imagine a queue at a coffee shop: customers (messages) wait in line until a barista (the processor) is ready to take the next order. This helps manage workloads efficiently, allowing different parts of a system to communicate without being directly connected. It enhances reliability and performance by ensuring that messages don’t get lost, even if the system experiences delays or failures, allowing for smoother, more organized interactions between different applications or services.
