24. Event Driven Architecture – Complete Guide for Backend & System Design

Event-Driven Architecture (EDA) is one of the most important patterns in modern backend systems, microservices, and distributed systems.
In this complete system design lecture, you will learn how events, producers, consumers, brokers, and asynchronous communication work together to build scalable and resilient applications.

This video explains Event-Driven Architecture in a simple, clear, and practical way, with real-world examples from Uber, Netflix, Amazon, Zomato, and modern microservices.

🚀 Why EDA Is Important

Almost every large-scale company today uses EDA:

Amazon, Uber, Flipkart, Swiggy, Netflix, Zomato, YouTube, Instagram, and Airbnb.

This architecture helps systems handle millions of events, making applications more scalable, resilient, and fault-tolerant.
