Cevap

Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) provides the customer with complete control over the operating system, middleware, and application layers of the virtual machines, making it the correct choice for migrating existing servers directly to the cloud without modifying their configurations.

Adım Adım Çözüm

1
Identify the key requirement of the scenario.
The organization needs to migrate existing on-premises application servers directly to Azure virtual machines without changing the application code or operating systems (often called 'lift-and-shift').
This establishes the level of control and configuration access required by the customer.
2
Evaluate the cloud service models based on the required level of control.
Infrastructure as a Service (IaaS) provides virtual machines, giving the customer control over the operating system, middleware, and applications, whereas PaaS and SaaS shift operating system management to the cloud provider.
Matching the requirements to the correct service model ensures a successful migration strategy.
