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

Veloce Automotive is migrating its infrastructure to the AWS Cloud. The migration team has identified two workloads:

1. A third-party inventory system that will be replaced by purchasing a software-as-a-service (SaaS) application from the AWS Marketplace.
2. A critical legacy web server that must be moved to Amazon EC2 immediately with zero modifications to the application code or configuration.

  5. E
    Retiring

Cevap

Repurchasing and Rehosting are the correct strategies.
Repurchasing is the correct strategy for the third-party inventory system because it is replaced by buying a Software-as-a-Service (SaaS) application. Rehosting is correct for the legacy web server because the server is moved to Amazon EC2 as-is with no modifications, which represents a lift-and-shift approach.

Adım Adım Çözüm

1
Analyze the requirement for the first workload: replacing a COTS system with a SaaS application from the AWS Marketplace.
This is identified as the Repurchasing strategy.
Repurchasing involves dropping the existing software license and purchasing a SaaS-based version of the tool.
2
Analyze the requirement for the second workload: moving a legacy web server to EC2 with zero modifications.
This is identified as the Rehosting strategy.
Rehosting, or lift-and-shift, involves migrating workloads directly to the cloud without modifying code or configuration.
