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

An online gaming studio is migrating its platform to the AWS Cloud. The migration team is evaluating two specific workloads:

1. A multiplayer matchmaking system that is currently a legacy monolithic application. The studio plans to completely rewrite this application to leverage a serverless, microservices-based architecture for dynamic scaling.
2. A player profiles database currently running on an on-premises PostgreSQL server. The studio wants to move this database to a managed cloud database service to reduce administrative overhead, without changing the database engine or the database schema.

Which of the following migration strategies should the studio select for these workloads? (Select TWO.)

  1. Refactoring (Re-architecting) for the multiplayer matchmaking systemAnswer
  2. Replatforming for the player profiles databaseAnswer
  3. C
    Rehosting for the multiplayer matchmaking system
  4. D
    Repurchasing for the player profiles database
  5. E
    Retaining for the multiplayer matchmaking system

Answer

Refactoring (Re-architecting) for the multiplayer matchmaking system, and Replatforming for the player profiles database.
Refactoring (Re-architecting) is correct for the matchmaking system because it involves rewriting the application code to implement a microservices-based, serverless architecture. Replatforming is correct for the player profiles database because the database is moved to a managed cloud database service (like Amazon RDS) to minimize administrative overhead while preserving the original database engine and schema.

Step-by-Step Solution

1
Analyze the requirements for the multiplayer matchmaking system.
The workload requires a complete rewrite to migrate from a monolithic structure to a serverless, microservices-based architecture.
This workload requires modifying the code and design to leverage cloud-native features, which defines the Refactoring (Re-architecting) migration strategy.
2
Analyze the requirements for the player profiles database.
The database needs to move to a managed service to offload administrative tasks, but without changing the engine or schema.
This workload involves shifting to a managed service (such as Amazon RDS for PostgreSQL) while keeping the core schema and engine the same, which defines the Replatforming (lift-tinker-and-shift) strategy.
