Microservices - CI/CD for Microservices
If a microservice is deployed independently, which of the following is a likely result during a system update?
AThe entire system must be taken offline
BOnly the updated microservice experiences downtime
CAll microservices restart simultaneously
DThe database schema must be updated for all services
Step-by-Step Solution
Solution:

  1. Step 1: Understand deployment scope

    Independent deployment limits downtime to the microservice being updated.

  2. Step 2: Contrast with monolithic deployment

    Monolithic systems require full system downtime, unlike microservices.

  3. Final Answer:

    Only the updated microservice experiences downtime -> Option B

  4. Quick Check:

    Independent deployment = Limited downtime [OK]
Quick Trick: Only updated service downtime, not whole system [OK]
Common Mistakes:
  • Assuming full system downtime
  • Believing all services restart together
  • Confusing database updates with deployment scope
