Messaging Queues

Messaging queues are software components that enable asynchronous communication between distributed systems by storing and forwarding messages. They decouple producers (senders) from consumers (receivers), allowing applications to process data at different rates and improving reliability and scalability. Common implementations include message brokers like RabbitMQ, Apache Kafka, and Amazon SQS.

Also known as: Message Queues, Message Brokers, MQ, Event Queues, Pub/Sub Systems

Why learn Messaging Queues?

Developers should learn messaging queues when building microservices, event-driven architectures, or systems requiring reliable, scalable data processing, such as in e-commerce order handling or real-time analytics. They are essential for handling high-throughput scenarios, ensuring fault tolerance, and managing workload spikes without data loss.
