You design a microservice system where services must remain available even if dependent services fail intermittently. Which advanced pattern combination best handles this edge case?

hard📝 Trade-off Q15 of 15

Microservices - Advanced Patterns

ASynchronous calls with no retries to avoid delays.

BSingle monolithic service to avoid network failures.

CCircuit breaker with fallback responses and event-driven retries.

DNo error handling to keep code simple.

Step-by-Step Solution

Solution:

Step 1: Understand availability needs
Services must stay responsive despite failures in dependencies.
Step 2: Combine patterns for resilience
Circuit breakers stop calls to failing services, fallback responses provide defaults, and event-driven retries handle eventual success.
Final Answer:
Circuit breaker with fallback responses and event-driven retries. -> Option C
Quick Check:
Combine circuit breaker + fallback + retries for availability [OK]

Quick Trick: Combine circuit breaker, fallback, and retries for resilience [OK]

Common Mistakes:

Using synchronous calls blocks availability
Monolith avoids network but loses scalability
No error handling causes system crashes
