Microservices - Advanced Patterns

ASidecar sends request without main service involvement

BMain service sends request to Sidecar, Sidecar resolves address and forwards request

CMain service directly queries the service registry and sends request

DMain service ignores Sidecar and sends request to a fixed IP

Step-by-Step Solution

Solution:

Step 1: Understand Sidecar role in service discovery
The Sidecar intercepts requests from the main service to resolve service addresses dynamically.
Step 2: Analyze request flow
The main service sends the request to the Sidecar, which looks up the destination and forwards the request accordingly.
Final Answer:
Main service sends request to Sidecar, Sidecar resolves address and forwards request -> Option B
Quick Check:
Service discovery flow = Main to Sidecar to destination [OK]

Quick Trick: Sidecar handles discovery, main service sends requests through it [OK]

Common Mistakes:

Assuming main service queries registry directly
Thinking Sidecar sends requests alone
Ignoring Sidecar in request flow
