You want to add secure communication (TLS encryption) to an existing microservice without changing its code. How does the Sidecar pattern help achieve this?

hard📝 Conceptual Q15 of 15

Microservices - Advanced Patterns

ABy rewriting the service code to include TLS libraries

BBy deploying a Sidecar proxy that handles TLS encryption and decryption alongside the service

CBy moving the service to a secure server only

DBy disabling all external communication to the service

Step-by-Step Solution

Solution:

Step 1: Understand Sidecar role in adding features
The Sidecar can run a proxy that manages TLS encryption without changing the main service code.
Step 2: Compare other options with Sidecar benefits
Rewriting code, moving servers, or disabling communication do not use Sidecar advantages.
Final Answer:
By deploying a Sidecar proxy that handles TLS encryption and decryption alongside the service -> Option B
Quick Check:
Sidecar proxy adds TLS without code change = B [OK]

Quick Trick: Sidecar proxy adds TLS, no code rewrite needed [OK]

Common Mistakes:

Thinking code rewrite is needed for TLS
Assuming moving servers secures communication alone
Believing disabling communication is a solution
