Microservices - Resilience Patterns

Which of the following is a correct way to implement graceful degradation in a microservice call?

ARestart the entire microservice cluster immediately

BReturn an error and stop the entire request flow

CIgnore the failure and return no response

DUse a fallback response when the called service is unavailable

Step-by-Step Solution

Solution:

Step 1: Identify how graceful degradation handles failures
It uses fallback responses or simpler data to keep the system responsive.
Step 2: Match the option that uses fallback
Use a fallback response when the called service is unavailable describes using fallback response when a service is down, which is correct.
Final Answer:
Use a fallback response when the called service is unavailable -> Option D
Quick Check:
Fallback response = graceful degradation [OK]

Quick Trick: Fallback response is key to graceful degradation [OK]
