Step-by-Step Solution
Solution:
Step 1: Understand microservices independence principle
Microservices should be loosely coupled and not share state directly.Step 2: Identify the error from options
Sharing state causes tight coupling; other options are correct practices.Final Answer:
Tight coupling through shared state breaks microservices principles -> Option CQuick Check:
Shared state = Tight coupling error [OK]
Quick Trick: Avoid shared state to keep services independent [OK]
Common Mistakes:
- Confusing REST API use as error
- Thinking separate servers cause failures
- Misunderstanding async messaging
