Message Queue technologies: How they work and why they matter?

Message queues help distributed systems communicate by asynchronously passing messages between services. They ensure reliable data processing, even when components are offline or experience high traffic.

Why Use Message Queues?

✔ Decoupling – Systems remain independent and scalable.
✔ Load Balancing – Evenly distribute work across multiple consumers.
✔ Fault Tolerance – Prevent data loss by persisting messages.
✔ Asynchronous Processing – Improve performance by handling tasks in the background.

Popular Message Queue Technologies

✔ Choosing the right message queue depends on your system’s needs—Kafka is great for event streaming, while RabbitMQ suits transactional messaging.
