Microservices - Service Mesh
What role does a sidecar proxy play in a service mesh?
AIt replaces the main application logic
BIt stores data for microservices
CIt acts as a database for the service mesh
DIt manages network communication between microservices transparently
Step-by-Step Solution
Solution:

  1. Step 1: Understand sidecar proxy function

    A sidecar proxy runs alongside each microservice instance to handle communication tasks like routing and security without changing the service code.

  2. Step 2: Identify correct role in service mesh

    It manages network communication transparently, enabling features like load balancing and retries.

  3. Final Answer:

    It manages network communication between microservices transparently -> Option D

  4. Quick Check:

    Sidecar proxy role = Manage communication [OK]
Quick Trick: Sidecar proxies handle communication, not data storage [OK]
Common Mistakes:
MISTAKES
  • Confusing sidecar proxy with database
  • Thinking sidecar replaces application logic
  • Assuming sidecar stores data
