Microservices - Advanced Patterns

ACircuit Breaker merges services; Bulkhead retries failed calls automatically

BCircuit Breaker stops calls to failing services; Bulkhead isolates failures to prevent spread

CCircuit Breaker increases retries; Bulkhead scales all services equally

DCircuit Breaker disables monitoring; Bulkhead reduces service instances

Step-by-Step Solution

Solution:

Step 1: Recall Circuit Breaker role
Circuit Breaker stops calls to failing services to avoid cascading failures.
Step 2: Recall Bulkhead role
Bulkhead isolates failures so they don't affect other parts of the system.
Step 3: Understand combined effect
Together, they stop failures early and contain their impact, improving resilience.
Final Answer:
Circuit Breaker stops calls to failing services; Bulkhead isolates failures to prevent spread -> Option B
Quick Check:
Combined patterns = Stop calls + isolate failures [OK]

Quick Trick: Combine stop calls and isolate failures for strong resilience [OK]
