Kafka - Event-Driven Architecture
What is the main reason event-driven architecture helps applications scale better?
AIt forces all parts of the app to run in a single sequence.
BIt stores all data in one central database for faster access.
CIt allows different parts of the app to work independently by sending messages.
DIt requires fewer servers to run the app.
Step-by-Step Solution
Solution:
  1. Step 1: Understand event-driven independence

    Event-driven design lets parts of an app send messages and work independently without waiting for each other.
  2. Step 2: Connect independence to scaling

    This independence means tasks can run at the same time, helping the app handle more work smoothly as it grows.
  3. Final Answer:

    It allows different parts of the app to work independently by sending messages. -> Option C
  4. Quick Check:

    Event-driven = Independent parts = Scales well [OK]
Quick Trick: Event-driven means parts work alone and talk by messages [OK]
Common Mistakes:
MISTAKES
  • Thinking event-driven forces sequential processing
  • Believing event-driven centralizes all data
  • Assuming event-driven reduces server count automatically
