Zorluk: OrtaShared Responsibility Model

A company currently hosts a legacy web application on Azure Virtual Machines. To reduce administrative overhead, the IT team plans to migrate the application to Azure App Service.

How does the responsibility for operating system patching change after this migration is complete?

  1. The responsibility for patching the operating system shifts entirely from the customer to Microsoft.Cevap
  2. B
    The customer remains responsible for patching the operating system, but Microsoft takes over the physical host maintenance.
  3. C
    Microsoft was already responsible for patching the operating system of the Virtual Machines, so there is no change in responsibility.
  4. D
    The responsibility shifts to Microsoft for both the operating system patching and all application-level configurations.

Cevap

The responsibility for patching the operating system shifts entirely from the customer to Microsoft.
In the Shared Responsibility Model, the boundary of responsibility shifts depending on the cloud service type. In Infrastructure as a Service (IaaS), such as Azure Virtual Machines, the customer has control over and is responsible for patching and configuring the operating system. In Platform as a Service (PaaS), such as Azure App Service, Microsoft manages the operating system, middleware, and runtime, shifting the responsibility of patching the operating system entirely to Microsoft.

Adım Adım Çözüm

1
Identify the service models involved in the transition.
The application is migrating from Azure Virtual Machines (Infrastructure as a Service, or IaaS) to Azure App Service (Platform as a Service, or PaaS).
Understanding the service models is necessary to apply the Shared Responsibility Model rules.
2
Analyze the responsibility for operating system patching in IaaS.
In IaaS, the customer is responsible for managing and patching the guest operating system.
Determines the baseline responsibility before migration.
3
Analyze the responsibility for operating system patching in PaaS.
In PaaS, the cloud provider (Microsoft) manages the operating system, including patching, while the customer manages applications and data.
Determines the new responsibility allocation after migration.
4
Compare the change in responsibility to identify the correct description.
Responsibility for patching shifts from the customer to Microsoft.
Selects the option that correctly describes this shift.
