A commercial real estate firm plans to migrate its legacy on-premises workloads to the AWS Cloud. The migration team has identified two key workloads for the first phase of migration:
* Workload 1: A property-valuation application running on virtual machines that must be migrated quickly to meet a data center exit deadline, without modifying the application code or configuration.
* Workload 2: A legacy document collaboration system that the firm wants to decommission entirely, replacing it with a fully managed commercial third-party Software-as-a-Service (SaaS) solution.
Which two migration strategies should the firm implement for these workloads? (Select TWO.)
- Rehosting for Workload 1, to quickly migrate the virtual machines to Amazon EC2 without changing application code or configurations.Answer
- Repurchasing for Workload 2, to replace the existing collaboration platform with a commercial SaaS solution.Answer
- CReplatforming for Workload 1, to optimize and containerize the application to run on AWS Fargate.
- DRefactoring for Workload 2, to split the system into serverless microservices on AWS Lambda.
- ERetaining for Workload 2, to keep the collaboration system on-premises while decommissioned workloads are moved.
Answer
The correct migration strategies are Rehosting for Workload 1 and Repurchasing for Workload 2.
The correct strategies are Rehosting for Workload 1 and Repurchasing for Workload 2. Rehosting (often called lift-and-shift) is the best choice for Workload 1 because it allows virtual machines to be migrated directly to Amazon EC2 without code modifications, meeting the tight deadline. Repurchasing (often called drop-and-shop) is the best choice for Workload 2 because it replaces the legacy product with a cloud-hosted commercial third-party SaaS solution.
