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

VeloMotors, an automotive manufacturing company, is migrating its legacy supply-chain tracking system to the AWS Cloud. The application currently runs on physical servers in their on-premises data center. To meet a strict data center evacuation deadline, the migration team decides to move the virtual machine images directly to Amazon EC2 instances without modifying the application code, database schema, or operating system configuration. Which of the following migration strategies is VeloMotors utilizing for this system?

  1. A
    Replatforming
  2. B
    Refactoring
  3. RehostingAnswer
  4. D
    Repurchasing

Answer

Rehosting
Rehosting (lift-and-shift) is a migration strategy where applications are moved to the cloud as-is, without code modifications or configuration changes. Since VeloMotors is copying virtual machine images directly to Amazon EC2 to meet their deadline without modifying the code, OS, or database, this is Rehosting.

Step-by-Step Solution

1
Analyze the migration scenario constraints and details.
The virtual machine images are being moved directly to Amazon EC2 instances with zero changes to the application code, database, or OS.
This establishes that the application is being migrated as-is without any modifications.
2
Match the scenario characteristics to the correct migration strategy from the 6 Rs.
Moving applications to the cloud as-is without code modifications matches the definition of Rehosting (lift-and-shift).
This differentiates Rehosting from strategies like Replatforming (minor tweaks) or Refactoring (major code changes).
