Zenith Commerce is planning to migrate its on-premises application portfolio to the AWS Cloud. The IT team has defined two specific goals for this migration phase:
1. Migrate their self-managed relational database to Amazon RDS for PostgreSQL to minimize database administration overhead, without changing the application's core logic.
2. Replace their legacy, self-managed customer relationship management (CRM) software with a cloud-native Software-as-a-Service (SaaS) solution.
Which of the following migration strategies should the company use to achieve these goals? (Select TWO.)
- Replatforming to migrate the relational database to Amazon RDSAnswer
- Repurchasing to transition the CRM software to a cloud-native SaaS solutionAnswer
- CRehosting to transition the CRM software to a cloud-native SaaS solution
- DRefactoring to migrate the relational database to Amazon RDS
- ERetaining to keep the CRM software running in its current on-premises environment
Answer
Replatforming should be used to migrate the database to Amazon RDS, and Repurchasing should be used to transition the CRM software to a SaaS solution.
The correct options are Replatforming and Repurchasing. Replatforming is correct for the database migration because it shifts the workload to a managed database service (Amazon RDS) to optimize operations without redesigning the application logic. Repurchasing is correct for the CRM system because the company is retiring its legacy, self-managed CRM software in favor of adopting a new cloud-native SaaS model.
