Difficulty: EasyUnderstand the benefits of and strategies for migration to the AWS Cloud

A regional hotel chain is migrating its IT workloads to the AWS Cloud. The IT team wants to move its legacy property management system to AWS exactly as-is, without making any modifications to the application code or database configuration, to ensure a fast transition. At the same time, the team has decided to decommission and shut down an outdated guest feedback system that is no longer used.

Answer

Rehosting and Retiring
The correct strategies are Rehosting and Retiring. Rehosting is the process of migrating a workload to AWS exactly as-is to save time and effort. Retiring is the strategy of decommissioning applications that no longer serve a business purpose.

Step-by-Step Solution

1
Analyze the migration plan for the legacy property management system.
The system is being migrated exactly as-is without any code or configuration changes.
This corresponds to the Rehosting (lift-and-shift) migration strategy.
2
Analyze the plan for the outdated guest feedback system.
The application is no longer useful and is being decommissioned and shut down.
This corresponds to the Retiring migration strategy.
