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

A global logistics company, LogiRoute, is migrating its on-premises infrastructure to the AWS Cloud. The migration team has identified two specific workloads:

1. A custom inventory database that they want to migrate to Amazon RDS to automate database patching and backups, without making any changes to the database structure or code.
2. A legacy document archiving system that is no longer used by any business departments and provides no ongoing value.

Which two of the following migration strategies represent the correct approach for these workloads? (Select TWO.)

  1. Replatforming for the custom inventory databaseAnswer
  2. Retiring for the legacy document archiving systemAnswer
  3. C
    Rehosting for the custom inventory database
  4. D
    Refactoring for the custom inventory database
  5. E
    Retaining for the legacy document archiving system

Answer

The correct strategies are Replatforming for the custom inventory database and Retiring for the legacy document archiving system.
Replatforming is correct for the database workload because it optimizes operations by adopting a managed database service (Amazon RDS) without modifying the schema or code. Retiring is correct for the archiving system because it is no longer used by the business, making decommissioning the optimal choice.

Step-by-Step Solution

1
Analyze the custom inventory database workload, which is being moved to Amazon RDS (a managed service) to reduce operational tasks like patching and backups without code alterations.
Determine that this lift-tinker-and-shift approach is Replatforming.
Replatforming involves modifying the platform to adopt managed services without changing the core application code.
2
Analyze the legacy document archiving system workload, which is decommissioned because it is no longer used and has no business value.
Determine that this decommissioning approach is Retiring.
Retiring refers to identifying assets that are no longer useful and turning them off during the migration.
