Microservices - Advanced Patterns

AThe Sidecar will automatically replace the main service

BThe Sidecar will consume too much CPU on the main server

CThe Sidecar cannot share the same environment and lifecycle with the main service

DThe Sidecar will cause the main service to crash

Step-by-Step Solution

Solution:

Step 1: Identify Sidecar deployment requirements
Sidecar must run alongside the main service in the same environment to share lifecycle and resources.
Step 2: Analyze the problem of separate server deployment
Deploying on a separate server breaks the Sidecar pattern because it loses environment and lifecycle sharing.
Final Answer:
The Sidecar cannot share the same environment and lifecycle with the main service -> Option C
Quick Check:
Sidecar must share environment; separate server breaks this = A [OK]

Quick Trick: Sidecar must share environment; separate server breaks pattern [OK]
