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

A healthcare provider plans to migrate its legacy IT infrastructure to the AWS Cloud. The migration team has identified two key workloads for the first phase:
1. An on-premises payroll application that is highly customized and expensive to maintain. The provider decides to decommission it and purchase a modern software-as-a-service (SaaS) payroll solution from a third-party vendor on AWS Marketplace.
2. A patient records database running on a self-managed server. The provider wants to migrate this database to Amazon Relational Database Service (Amazon RDS) to reduce administrative overhead, without making any modifications to the database schema or application code.

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

  1. Repurchasing for the payroll applicationCevap
  2. Replatforming for the patient records databaseCevap
  3. C
    Rehosting for the patient records database
  4. D
    Refactoring for the payroll application
  5. E
    Retaining for the patient records database

Cevap

The correct migration strategies are repurchasing for the payroll application and replatforming for the patient records database.
Repurchasing is the correct strategy for the payroll application because it involves replacing the legacy system with a commercial SaaS product or package. Replatforming is the correct strategy for the patient records database because the workload is moved to a managed cloud service (Amazon RDS) to achieve operational optimizations without changing the database schema or application architecture.

Adım Adım Çözüm

1
Analyze the migration plan for the payroll application.
The application is decommissioned and replaced with a third-party SaaS solution on AWS Marketplace.
This 'drop-and-shop' approach represents the Repurchasing strategy.
2
Analyze the migration plan for the patient records database.
The database is moved to a fully managed database service (Amazon RDS) to reduce operational overhead without changing schema or code.
This optimization ('tinkering') while keeping the core architecture intact represents the Replatforming strategy.
