easy📝 Conceptual Q11 of 15
Step-by-Step Solution
Solution:
Step 1: Understand event-driven communication
Event-driven systems use messages or events to notify other services asynchronously, without waiting for a reply.Step 2: Compare with request-driven communication
Request-driven systems make direct calls and wait for responses, which is synchronous communication.Final Answer:
Services communicate by sending messages without waiting for immediate responses. -> Option AQuick Check:
Event-driven = asynchronous messaging [OK]
Quick Trick: Event-driven means no waiting for replies, just messages [OK]
Common Mistakes:
MISTAKES- Confusing event-driven with synchronous calls
- Thinking event-driven requires shared databases
- Assuming event-driven always uses batch processing
