AWS Certified Cloud Practitioner (CLF-C02) — Question 505

A company runs a legacy workload in an on-premises data center. The company wants to migrate the workload to AWS. The company does not want to make any changes to the workload.

Which migration strategy should the company use?

Answer options

• A. Repurchase
• B. Replatform
• C. Rehost
• D. Refactor

Correct answer: C

Explanation

Rehosting, often referred to as 'lift-and-shift', is the strategy of migrating workloads to the cloud without making any modifications to the application or architecture. Replatforming involves making minor optimizations during migration, while refactoring requires a complete rewrite to make the application cloud-native. Repurchasing involves replacing the existing application with a different product, such as a SaaS platform.
