Question

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

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.)

  1. Repurchasing for the CRM systemAnswer
  2. Rehosting for the transaction processing applicationAnswer
  3. C
    Replatforming for the transaction processing application
  4. D
    Refactoring for the CRM system
  5. E
    Retaining 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.

Step-by-Step Solution

1
Analyze the CRM system migration requirement
The team decided to replace the legacy CRM system entirely with a Software-as-a-Service (SaaS) platform, which corresponds to the Repurchasing strategy.
Repurchasing is defined as moving to a different product, typically a SaaS model.
2
Analyze the transaction processing application migration requirement
The team needs to migrate virtual machines quickly with minimal changes to meet a tight datacenter exit deadline, which corresponds to the Rehosting strategy.
Rehosting (lift-and-shift) involves migrating applications to the cloud without modifying their code or architecture, allowing for rapid migration.
