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

A logistics company wants to migrate its legacy shipment-tracking application to the AWS Cloud. The primary goal is to complete the migration as quickly as possible to meet an upcoming data center evacuation deadline, without making any modifications to the application code or architecture. Which migration strategy should the company use to meet this requirement?

    Replatforming
  2. RehostingAnswer
  3. C
    Refactoring
  4. D
    Repurchasing

Answer

Rehosting
The correct strategy is Rehosting. Rehosting, often referred to as 'lift-and-shift', involves migrating applications from an on-premises environment to AWS virtual machines (Amazon EC2) with no changes to the application code, architecture, or configuration. This makes it the fastest migration method and ideal for urgent data center evacuations.

Step-by-Step Solution

1
Analyze the company's constraints and goals from the scenario.
The company needs to migrate quickly due to a deadline and wants to make zero code or architecture changes.
This establishes the requirements for the migration strategy.
2
Map the zero-change, fast migration requirement to the AWS migration strategies (6 Rs).
Rehosting is identified as the strategy that copies the application to the cloud as-is without code changes.
Rehosting matches the requirement of minimal modification and rapid deployment.
