Zorluk: OrtaUnderstand the benefits of and strategies for migration to the AWS Cloud

Vanguard Logistics plans to migrate its legacy on-premises route optimization application to the AWS Cloud. The application currently runs on an outdated, unsupported Linux distribution. To minimize migration time while improving operational support, the company decides to migrate the application to Amazon EC2 instances running a modern, supported Amazon Linux operating system without modifying the core application code. Which cloud migration strategy is Vanguard Logistics using?

  1. ReplatformingCevap
  2. B
    Rehosting
  3. C
    Refactoring
  4. D
    Repurchasing

Cevap

Replatforming
Replatforming (also known as lift-tinker-and-shift) is correct because the company is making a minor optimization—upgrading the underlying operating system to a supported version—without changing the core architecture or code of the application.

Adım Adım Çözüm

1
Analyze the migration scenario details
The application code remains unchanged, but the underlying operating system is upgraded to a supported version during the migration.
This establishes that the migration involves some modification at the platform level (operating system upgrade) but no modification to the core application code.
2
Map the observed changes to the 6 Rs migration strategies
Upgrading the operating system without changing the core application code is classified as Replatforming (lift-tinker-and-shift).
Rehosting preserves the operating system environment as-is, whereas Replatforming allows small changes (like OS or runtime upgrades) to meet platform compatibility and support requirements without full re-architecting.
