What is the main difference between event choreography and event orchestration in Kafka-based systems?
AChoreography lets services react independently; orchestration uses a central controller.
BChoreography requires a central controller; orchestration lets services react independently.
CBoth use a central controller but differ in message format.
DChoreography is synchronous; orchestration is asynchronous.
Step-by-Step Solution
Solution:
  1. Step 1: Understand event choreography

    Event choreography means each service listens and reacts to events on its own without a central manager.
  2. Step 2: Understand event orchestration

    Event orchestration means a central controller tells services what to do and when, managing the flow.
  3. Final Answer:

    Choreography lets services react independently; orchestration uses a central controller. -> Option A
  4. Quick Check:

    Choreography = independent reaction, Orchestration = central control [OK]
Quick Trick: Choreography = no boss; orchestration = boss controls flow [OK]
Common Mistakes:
  • Confusing which uses a central controller
  • Thinking both require central control
  • Mixing synchronous and asynchronous concepts
