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

NovaPeak Manufacturing is planning to migrate two of its IT workloads to the AWS Cloud. First, they want to migrate a legacy inventory database to Amazon EC2 without making any architectural or code changes. Second, they plan to replace their on-premises customer relationship management (CRM) software with a cloud-based Software-as-a-Service (SaaS) subscription. Which two cloud migration strategies should NovaPeak Manufacturing select for these workloads? (Select TWO.)

  1. Rehosting (Lift-and-Shift)Answer
  2. Repurchasing (Drop-and-Shop)Answer
  3. C
    Replatforming (Lift-Tinker-and-Shift)
  4. D
    Refactoring (Re-architecting)
  5. E
    Retaining (Keep)

Answer

The correct strategies are Rehosting (Lift-and-Shift) and Repurchasing (Drop-and-Shop).
The correct strategies are Rehosting (Lift-and-Shift) and Repurchasing (Drop-and-Shop). Rehosting is correct because moving the legacy database to Amazon EC2 without any changes is a classic lift-and-shift approach. Repurchasing is correct because moving from self-hosted software to a SaaS subscription represents purchasing a new product.

Step-by-Step Solution

1
Analyze the first workload requirement: migrating the legacy database to Amazon EC2 without making any architectural or code changes.
Identify that moving a workload 'as-is' corresponds to the Rehosting (Lift-and-Shift) migration strategy.
This strategy allows organizations to quickly migrate workloads without redesigning the application.
2
Analyze the second workload requirement: replacing the on-premises CRM software with a cloud-based SaaS subscription.
Identify that discarding an existing application to purchase a new product or utility service (like SaaS) corresponds to the Repurchasing (Drop-and-Shop) strategy.
This strategy shifts the business to a different product or platform, often managed by a third-party vendor.
