Zorluk: OrtaUnderstand the benefits of and strategies for migration to the AWS Cloud

OceanGlide Maritime, a shipping logistics provider, is planning to migrate its on-premises infrastructure to the AWS Cloud. The migration team has identified two initial workloads to migrate:

1. A proprietary port scheduling application that runs on a legacy operating system. The team needs to move this workload to AWS quickly with zero code modifications to allow the immediate decommissioning of their physical server.
2. An on-premises commercial database engine. The team wants to migrate this database to a managed service in AWS (specifically Amazon RDS) to reduce licensing fees and offload operating system patching and backups, without changing the core database schema or application logic.

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

  1. Rehosting for the port scheduling applicationCevap
  2. Replatforming for the commercial database systemCevap
  3. C
    Refactoring for the port scheduling application
  4. D
    Repurchasing for the commercial database system
  5. E
    Rehosting for the commercial database system

Cevap

Rehosting is correct for the port scheduling application, and Replatforming is correct for the commercial database system.
The correct options are Rehosting for the port scheduling application and Replatforming for the commercial database system. Rehosting (lift-and-shift) is appropriate because the legacy port scheduling application needs to be moved quickly with zero changes. Replatforming (lift-tinker-and-shift) is appropriate because the database is moving to a managed service (Amazon RDS) to reduce maintenance tasks (patching and backups) and database licensing costs, without core architectural changes.

Adım Adım Çözüm

1
Analyze the requirements for the legacy port scheduling application.
The application must be moved quickly with zero modifications to allow decommissioning of physical hardware. This matches Rehosting (lift-and-shift).
Rehosting allows rapid migration of workloads to the cloud without modifying the application code or configuration.
2
Analyze the requirements for the commercial database system.
The database must migrate to a managed service (Amazon RDS) to reduce licensing fees and administrative tasks (patching/backups) without changing the database schema or application logic. This matches Replatforming (lift-tinker-and-shift).
Replatforming involves modifying the hosting environment (e.g., moving from self-managed servers to managed Amazon RDS) to gain cloud efficiency without altering the core codebase.

Anahtar Kavram

Identifying AWS Cloud migration strategies (the 6 Rs), focusing on the distinction between Rehosting (lift-and-shift) and Replatforming (lift-tinker-and-shift).
