Why does a service mesh use sidecar proxies for observability instead of instrumenting application code directly?

hard📝 Conceptual Q10 of 15

Kubernetes - Service Mesh

AInstrumenting code is faster and more reliable

BSidecar proxies provide consistent telemetry without modifying application code

CSidecar proxies reduce network latency significantly

DApplication code cannot generate telemetry data

Step-by-Step Solution

Solution:

Step 1: Understand sidecar proxy advantage
Sidecar proxies intercept traffic transparently, providing consistent telemetry without needing to change application code.
Step 2: Analyze other options
Instrumenting code is more complex and error-prone. Sidecars do not primarily reduce latency. Application code can generate telemetry but requires changes.
Final Answer:
Sidecar proxies provide consistent telemetry without modifying application code -> Option B
Quick Check:
Sidecar proxies enable telemetry without code changes [OK]

Quick Trick: Sidecars avoid app code changes for telemetry [OK]
