Скачать или смотреть Why Message Queues Are Used in Scalable Systems

A message queue is one of the most important building blocks in modern distributed systems.

In this video, we explain:
What a message queue actually is
Why systems use queues instead of direct processing
How asynchronous execution improves performance
Fault tolerance and retry handling
Load balancing and task prioritization
Real-world use cases like order processing, emails, payments, and notifications

Using a simple pizza shop analogy, you’ll understand how message queues allow systems to respond instantly while processing work reliably in the background.

If you’re learning system design, backend engineering, or preparing for interviews — this concept is essential.
