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

A media company, CineArchive, is migrating its legacy portfolio to AWS. The migration team has identified two specific workloads:

1. A legacy document management system that runs on an old operating system and relies on a specific local filesystem structure. The team wants to migrate this workload to AWS as quickly as possible with zero code or configuration changes.
2. A relational database running on-premises that suffers from high administrative overhead. The team wants to move the database to a managed service in AWS to reduce database administration tasks (such as patching and backups) without modifying the database schema or rewriting the SQL queries.

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

  1. Rehosting (lift-and-shift) for the document management systemAnswer
  2. Replatforming (lift-tinker-and-shift) for the database workloadAnswer
  3. C
    Refactoring (re-architecting) for the database workload
  4. D
    Repurchasing for the document management system
  5. E
    Retaining for the database workload

Answer

The correct strategies are Rehosting (lift-and-shift) for the document management system and Replatforming (lift-tinker-and-shift) for the database workload.
Rehosting (lift-and-shift) is the correct strategy for the document management system because it allows moving the workload to the cloud without any code or configuration changes. Replatforming (lift-tinker-and-shift) is the correct strategy for the database workload because moving to a managed service (such as Amazon RDS) reduces database management overhead (e.g., patching, backups) while keeping the database schema and SQL queries intact.

Step-by-Step Solution

1
Analyze the requirements for the legacy document management system.
The requirement specifies migrating the workload as quickly as possible with zero code or configuration changes. This maps directly to the Rehosting (lift-and-shift) migration strategy.
Rehosting involves copying the existing application to the cloud without modifying its architecture or code.
2
Analyze the requirements for the relational database.
The requirement specifies moving to a managed service to reduce administrative overhead (like patching and backups) without modifying the schema or rewriting queries. This maps directly to the Replatforming (lift-tinker-and-shift) strategy.
Replatforming involves modifying the runtime environment (e.g., moving to a managed database service like Amazon RDS) to optimize operations without changing the core application architecture.
