A financial services firm, WealthFlow, is planning to migrate its infrastructure to the AWS Cloud. The migration team has identified two specific workloads for the first phase:
* A legacy customer relationship management (CRM) system that requires significant maintenance. The team decides to replace it entirely with a cloud-native Software-as-a-Service (SaaS) platform.
* A core transaction processing application running on-premises virtual machines. The team wants to move this application to AWS quickly with minimal modifications to the code or architecture to meet a tight datacenter exit deadline.
Which migration strategies under the AWS Migration 6 Rs framework should the firm use for these workloads? (Select TWO.)
- Repurchasing for the CRM systemAnswer
- Rehosting for the transaction processing applicationAnswer
- CReplatforming for the transaction processing application
- DRefactoring for the CRM system
- ERetaining for the transaction processing application
Answer
The firm should use Repurchasing for the CRM system and Rehosting for the transaction processing application.
The correct strategy for the legacy CRM system is Repurchasing because the firm is discarding the existing system to adopt a SaaS solution. The correct strategy for the transaction processing application is Rehosting because they are moving virtual machines to AWS with minimal modifications to speed up the datacenter exit.
