CV0-004 Practice Question: Move its on-premises web application to the cloud…
A company wants to move its on-premises web application to the cloud with minimal code changes to reduce risk. Which deployment strategy is most appropriate?
⚠ Common exam trap
A common mix-up: candidates confuse 'Replatform' with 'Rehost' because both involve moving to the cloud, but Replatform requires code changes to leverage managed services (e.g., replacing a self-managed database with Amazon RDS), which increases risk and violates the 'minimal code changes' constraint.

Correct answer & explanation
✓
Rehost
The Rehost (lift-and-shift) strategy is most appropriate because it moves the on-premises web application to the cloud with minimal code changes, directly reducing risk. By migrating the existing virtual machines or physical servers to cloud instances (e.g., AWS EC2 or Azure VMs) without modifying the application architecture, the company preserves the current codebase and operational behavior. This approach avoids the complexity and potential errors associated with rewriting or refactoring code, making it the safest choice for a risk-averse migration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Refactor
Why it's wrong here
Refactor requires rewriting the application for cloud-native features.
- ✓
Rehost
Why this is correct
Rehost moves the application as-is, minimizing code changes.
- ✗
Replatform
Why it's wrong here
Replatform involves some code changes to leverage cloud services.
- ✗
Rebuild
Why it's wrong here
Rebuild means completely redesigning the application.
