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

TerraGrow Agriculture is planning to migrate its legacy on-premises applications to the AWS Cloud. The company has identified two specific workloads for the first phase:

1. A proprietary crop-yield analysis application that must be moved immediately to AWS with absolutely no modifications to its code or configuration.
2. An on-premises legacy customer relationship management (CRM) database that will be decommissioned and replaced with a modern cloud-based Software-as-a-Service (SaaS) platform.

Which two AWS migration strategies should the company use to meet these requirements? (Select TWO.)

  5. E

Cevap

Rehosting and Repurchasing
Rehosting and Repurchasing are the correct strategies. Rehosting, often called 'lift-and-shift', moves workloads to AWS without modifying code or configuration, aligning with the crop-yield application requirement. Repurchasing, or 'drop-and-shop', replaces legacy systems with new cloud-native Software-as-a-Service (SaaS) products, matching the CRM replacement requirement.

Adım Adım Çözüm

1
Analyze the migration requirements for the first workload (crop-yield analysis application).
The application must be moved quickly with zero changes to code or configuration, which maps to Rehosting (lift-and-shift).
Rehosting involves copying existing servers to AWS without modifications.
2
Analyze the migration requirements for the second workload (legacy CRM database).
The CRM database is being retired in favor of a new SaaS solution, which maps to Repurchasing (drop-and-shop).
Repurchasing involves adopting a different product, typically cloud-hosted SaaS, to replace a legacy system.
