Building Scalable Systems: The Power of Pub-Sub Architecture

There are various ways you can communicate with servers to get a response. The method we almost always end up using is REST API polling. But when you need real-time, event-driven scalability, polling falls apart.

  • Asynchronous: Events are processed in the background without blocking the main thread.
  • Scalability: Easily add more consumers to handle high load (like Redis Streams or Apache Kafka).
