Microservices - Migration from Monolith

Consider this migration step code snippet for routing traffic:

if (user.isBetaTester) {
  routeToNewService();
} else {
  routeToOldService();
}

What will happen if a user is not a beta tester?

AUser traffic is dropped

BUser traffic goes to the new service

CUser traffic goes to the old service

DUser traffic causes an error

Step-by-Step Solution

Solution:

Step 1: Analyze the condition
If user.isBetaTester is false, the else branch runs.
Step 2: Determine routing for else branch
The else branch calls routeToOldService(), so traffic goes to old service.
Final Answer:
User traffic goes to the old service -> Option C
Quick Check:
Non-beta users = old service routing [OK]

Quick Trick: False condition triggers else branch routing [OK]
