  3. It shifts from the municipal government to Microsoft.Cevap
  4. D

Cevap

The responsibility for operating system patching shifts from the municipal government to Microsoft.
Migrating from Azure Virtual Machines (an Infrastructure as a Service, or IaaS, offering) to Azure App Service (a Platform as a Service, or PaaS, offering) shifts several management responsibilities. Under IaaS, the customer is fully responsible for configuring, updating, and patching the operating system of the virtual machines. Under PaaS, Microsoft manages the physical infrastructure, virtualization layer, and the operating system, which includes applying all OS patches. Therefore, the responsibility for operating system patching shifts from the municipal government to Microsoft.

Adım Adım Çözüm

1
Identify the service models before and after the migration.
The initial state (Azure Virtual Machines) is Infrastructure as a Service (IaaS). The target state (Azure App Service) is Platform as a Service (PaaS).
Understanding the service models is necessary to apply the rules of the Shared Responsibility Model.
2
Analyze how responsibility for operating system management differs between IaaS and PaaS.
In IaaS, the customer (municipal government) is responsible for managing the operating system, including updates and patching. In PaaS, the cloud provider (Microsoft) manages the operating system, middleware, and runtime.
Comparing the responsibility boundaries determines the direction of the shift.
3
Formulate the change in responsibility.
Since the responsibility transitions from the customer (IaaS) to the cloud provider (PaaS), the responsibility for operating system patching shifts from the municipal government to Microsoft.
This matches the correct option description.
