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

A healthcare provider, Sanitas Health, is planning the migration of its IT systems to the AWS Cloud. The organization has decided to migrate its patient portal database from a self-managed database to Amazon RDS for PostgreSQL to reduce administrative tasks, without making any modifications to the application code. Additionally, they will decommission their on-premises archival application and replace it with a new Software-as-a-Service (SaaS) document management solution available on the AWS Marketplace. Which two AWS Cloud Migration strategies are being implemented in this scenario? (Select TWO).

  1. Replatforming, for the patient portal database migrationCevap
  2. Repurchasing, for the archival application migrationCevap
  3. C
    Rehosting, for the patient portal database migration
  4. D
    Refactoring, for the archival application migration
  5. E
    Retaining, to keep the patient portal on-premises to convert operating expenditures (OpEx) into capital expenditures (CapEx)

Cevap

Replatforming for the patient portal database and Repurchasing for the archival application.
The correct options are Replatforming (for the patient portal database) and Repurchasing (for the archival application). Replatforming involves modifying the platform on which the application runs—such as using Amazon RDS instead of a self-managed database—to optimize operation without rewriting application code. Repurchasing involves moving to a different product or service model, such as purchasing a SaaS solution from the AWS Marketplace to replace an on-premises system.

Adım Adım Çözüm

1
Analyze the database migration strategy
The patient portal database is moved from a self-managed infrastructure to a managed database service (Amazon RDS) without modifying the application code.
This lift-tinker-and-shift pattern matches Replatforming, where database management tasks are offloaded to AWS while keeping the core application the same.
2
Analyze the archival application migration strategy
The on-premises archival application is decommissioned and replaced with a Software-as-a-Service (SaaS) solution from the AWS Marketplace.
This drop-and-shop pattern matches Repurchasing, which involves changing the software licensing model or vendor for a cloud-managed SaaS offering.
