Zorluk: KolayShared Responsibility Model

A news agency runs its website on an Azure Virtual Machine (IaaS). To eliminate the administrative effort of managing and patching the operating system, the agency migrates the website to Azure App Service (PaaS). Under the Microsoft Azure shared responsibility model, how does this migration change the responsibility for operating system patching?

  1. Responsibility for patching the operating system shifts from the customer to Microsoft.Cevap
  2. B
    Responsibility for patching the operating system remains with the customer because they still own the hosted application.
  3. C
    Responsibility for patching the operating system shifts from Microsoft to the customer.
  4. D
    Responsibility for patching the operating system becomes a shared task where Microsoft provides the patches and the customer must manually approve and apply them.

Cevap

Responsibility for patching the operating system shifts from the customer to Microsoft.
In Infrastructure as a Service (IaaS), such as Azure Virtual Machines, the customer is responsible for maintaining and patching the operating system. When migrating to a Platform as a Service (PaaS) offering like Azure App Service, Microsoft assumes responsibility for the operating system, hardware, and physical infrastructure, while the customer remains responsible for the applications and data they deploy.

Adım Adım Çözüm

1
Identify the initial service model and its OS responsibility.
The website starts on an Azure Virtual Machine, which is an Infrastructure as a Service (IaaS) offering. In IaaS, the customer is responsible for managing, configuring, and patching the operating system.
To understand the change in responsibility, we must first establish the starting point.
2
Identify the target service model and its OS responsibility.
The website is migrated to Azure App Service, which is a Platform as a Service (PaaS) offering. In PaaS, Microsoft manages and patches the underlying operating system, runtime, and hardware.
Comparing the two models determines how the responsibility shifts.
3
Determine the direction of the responsibility shift.
Responsibility for OS patching shifts from the customer (in IaaS) to Microsoft (in PaaS).
This matches the migration described in the scenario.
