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

PixelForge Studios is planning to migrate its operations to the AWS Cloud. The IT team has categorized two of their workloads for migration:

First, they will replace their self-managed on-premises human resources (HR) application with a third-party Software-as-a-Service (SaaS) solution available on the AWS Marketplace.

Second, they will move their web application's underlying MySQL database to Amazon Relational Database Service (Amazon RDS) to eliminate database administration tasks, while leaving the application code unchanged.

Which two of the following AWS Cloud migration strategies describe these plans? (Select TWO.)

  1. RepurchasingAnswer
  2. ReplatformingAnswer
  3. C
    Rehosting
  4. D
    Refactoring
  5. E
    Retaining

Answer

The correct strategies are Repurchasing and Replatforming.
The correct strategies are Repurchasing and Replatforming. Replacing the legacy HR application with a third-party Software-as-a-Service (SaaS) solution corresponds to a Repurchasing strategy (sometimes referred to as drop-and-shop). Moving the database to a managed service like Amazon Relational Database Service (Amazon RDS) to eliminate database administration tasks while keeping the core application code intact represents a Replatforming strategy (also known as lift-tinker-and-shift).

Step-by-Step Solution

1
Analyze the first migration workload: replacing the on-premises HR application with a third-party SaaS solution on AWS Marketplace.
Identify this as the Repurchasing strategy, which involves transitioning to a different product or platform (often SaaS) and purchasing licenses.
The defining characteristic of Repurchasing is moving from a self-managed product to a SaaS model.
2
Analyze the second migration workload: moving the MySQL database to Amazon RDS to reduce management overhead without altering application code.
Identify this as the Replatforming strategy, where minor optimizations are made to leverage cloud-managed services without redesigning the core application architecture.
Migrating a database to a managed service like Amazon RDS without modifying code is a classic replatforming scenario.
