Correct answer & explanation
✓
Independent deployability and scaling of services
Microservices allow independent deployment and scaling of services, which is a key advantage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Easier end-to-end testing
Why it's wrong here
End-to-end testing is actually harder in microservices due to distributed service dependencies, network latency, and data consistency challenges across multiple databases, whereas a monolith’s single codebase and shared database simplify such testing. This option is tempting because end-to-end testing verifies user workflows, and in a small monolith it is indeed straightforward, but the stem asks for a primary advantage of microservices, which is independent deployability and fault isolation, not testing ease.
- ✗
Lower operational overhead
Why it's wrong here
Microservices often increase operational complexity.
- ✗
Simpler inter-service communication
Why it's wrong here
Microservices often require complex communication patterns like REST or messaging.
- ✓
Independent deployability and scaling of services
Why this is correct
Each service can be deployed and scaled independently, improving agility.
