A logistics company, SwiftRoute Logistics, plans to migrate its on-premises package tracking application to the AWS Cloud. The migration team will move the application's web servers directly to Amazon EC2 instances without modification, but will transition its self-managed relational database to Amazon Relational Database Service (Amazon RDS) to eliminate database administration tasks. Which migration strategy is SwiftRoute Logistics using?
- ARehosting
- ReplatformingAnswer
- CRefactoring
- DRepurchasing
Answer
Replatforming is the correct migration strategy because the company is migrating its application to the cloud while making minor optimizations—specifically moving the database to a managed service (Amazon RDS) to reduce management overhead—without altering the core application architecture or code.
The strategy described is replatforming (also known as lift-tinker-and-shift). In this scenario, the core application code is migrated to Amazon EC2 without changes, but the database is moved to a managed database service (Amazon RDS) to reduce administrative overhead. This optimization of a component without changing the core application structure is the defining characteristic of replatforming.
