You want to add monitoring and security features to multiple microservices without changing their code. How does the sidecar proxy pattern help solve this problem at scale?

hard📝 Trade-off Q15 of 15

Microservices - Service Mesh

ABy centralizing monitoring and security in a single proxy for all services

BBy deploying a sidecar proxy with each service instance to handle monitoring and security independently

CBy rewriting each service to include monitoring and security code

DBy removing proxies and letting clients handle monitoring

Step-by-Step Solution

Solution:

Step 1: Understand scaling with sidecar proxies
Deploying a sidecar proxy alongside each service instance allows independent handling of monitoring and security without modifying service code.
Step 2: Compare with other options
Rewriting services is costly and error-prone; centralizing in one proxy creates a bottleneck; removing proxies loses control.
Final Answer:
By deploying a sidecar proxy with each service instance to handle monitoring and security independently -> Option B
Quick Check:
Sidecar per service instance scales features independently = C [OK]

Quick Trick: Sidecar per service instance scales features well [OK]

Common Mistakes:

MISTAKES

Thinking one proxy can handle all services centrally
Assuming code changes are needed for features
Ignoring scalability and bottleneck issues
