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

An aerospace manufacturing firm is evaluating its cloud migration strategy for two specific workloads:

* Workload 1: A customized commercial off-the-shelf (COTS) HR system that is nearing its license expiration. The company has decided to retire the system and purchase a subscription to a cloud-hosted Software-as-a-Service (SaaS) platform, migrating their active user records to the new SaaS platform.
* Workload 2: A proprietary Java application running on an on-premises web server. The engineering team plans to migrate the application to AWS by containerizing it and hosting it on AWS App Runner to reduce runtime management tasks. The application code will remain unchanged, but the team will adjust the application's configuration to use environment variables for database connections.

Which of the following migration strategies describe the planned paths for Workload 1 and Workload 2? (Select TWO.)

  1. Repurchasing for Workload 1Answer
  2. Replatforming for Workload 2Answer
  3. C
    Rehosting for Workload 2
  4. D
    Refactoring for Workload 1
  5. E
    Retaining for Workload 2

Answer

Repurchasing for Workload 1 and Replatforming for Workload 2
The correct choices are Repurchasing for Workload 1 and Replatforming for Workload 2. Repurchasing is the process of moving from a legacy or commercial off-the-shelf (COTS) license model to a cloud-based Software-as-a-Service (SaaS) subscription model. Replatforming involves modifying the deployment platform (e.g., containerizing it for a managed service like AWS App Runner) to gain benefits like reduced administrative overhead, without modifying the application's core code architecture.

Step-by-Step Solution

1
Analyze the migration plan and target destination for Workload 1.
Workload 1 is a commercial off-the-shelf (COTS) HR system that is being retired in favor of a subscription to a cloud-hosted SaaS platform.
Moving from an existing licensed application to a different cloud-hosted product (typically SaaS) is the definition of the Repurchasing strategy.
2
Analyze the migration plan and target destination for Workload 2.
Workload 2 is a Java application being containerized and moved to AWS App Runner without changing its core application code.
Deploying the workload to a managed container service to eliminate OS-level maintenance without altering its core architecture represents the Replatforming strategy (lift-tinker-and-shift).
3
Synthesize the findings to match the options.
The correct strategies are Repurchasing for Workload 1 and Replatforming for Workload 2.
This accurately reflects the chosen pathways for both workloads.
