ApexMart, a retail company, is planning to migrate its legacy on-premises web server to AWS EC2 instances with no changes to the application code or configuration. The company also wants to transition its IT budget from upfront hardware investments to a pay-as-you-go model. Which two of the following statements correctly describe the migration strategy used for the web server and the financial benefit of this migration?

  1. The migration strategy used is Rehosting (lift-and-shift).Answer
  2. The financial benefit is shifting from capital expenses (CapEx) to operating expenses (OpEx).Answer
  3. C
    The migration strategy used is Replatforming (lift-tinker-and-shift).
  4. D
    The financial benefit is shifting from operating expenses (OpEx) to capital expenses (CapEx).
  5. E
    The migration strategy used is Refactoring (re-architecting).

Answer

The migration strategy used is Rehosting (lift-and-shift), and the financial benefit is shifting from capital expenses (CapEx) to operating expenses (OpEx).
The correct options state that the strategy is Rehosting and the financial benefit is shifting from CapEx to OpEx. Rehosting represents migrating workloads with zero modifications (lift-and-shift). Shifting from upfront hardware purchasing to pay-as-you-go models replaces capital expenditures (CapEx) with operating expenditures (OpEx).

Step-by-Step Solution

1
Analyze the migration scenario for the web server.
The web server is being moved to AWS EC2 instances with zero changes to the application code or configuration. This represents a 'lift-and-shift' approach, which corresponds to the Rehosting migration strategy.
