Microservices - Real-World Architecture Case Studies
Which of the following is the correct way Netflix microservices discover each other?
AThrough DNS entries only
BDirect IP address hardcoding
CUsing Eureka Service Registry
DUsing a shared database
Step-by-Step Solution
Solution:

  1. Step 1: Understand service discovery in Netflix

    Netflix uses Eureka as a service registry where microservices register and discover each other dynamically.

  2. Step 2: Evaluate other options

    Hardcoding IPs or using DNS alone is not scalable; shared database is not used for discovery.

  3. Final Answer:

    Using Eureka Service Registry -> Option C

  4. Quick Check:

    Service discovery = Eureka Service Registry [OK]
Quick Trick: Eureka is Netflix's service registry [OK]
Common Mistakes:
  • Hardcoding IPs instead of dynamic discovery
  • Assuming DNS alone handles discovery
  • Using database for service discovery
