Consider this scenario: A microservice A is updated and deployed independently while microservice B continues running. What is the expected outcome?
ABoth microservices run without interruption during A's deployment
BMicroservice A cannot be deployed without stopping B
CThe entire system restarts after A's deployment
DMicroservice B will stop working until A finishes deployment
Step-by-Step Solution
Solution:
  1. Step 1: Understand independent deployment effect on running services

    Independent deployment means updating one service does not stop or affect others.
  2. Step 2: Analyze each option against this principle

    Only Both microservices run without interruption during A's deployment correctly states both services run without interruption.
  3. Final Answer:

    Both microservices run without interruption during A's deployment -> Option A
  4. Quick Check:

    Independent deployment = no interruption [OK]
Quick Trick: Remember: independent means no downtime for others [OK]
Common Mistakes:
  • Assuming deployment pauses all services
  • Thinking system restarts after one service update
  • Confusing deployment dependency between services
