Zorluk: OrtaShared Responsibility Model

A retail company is migrating its inventory tracking system from a custom application hosted on Azure Virtual Machines (IaaS) to Azure Blob Storage (PaaS) for unstructured data management. Under the Azure Shared Responsibility Model, how does the responsibility for operating system patching and physical host security change after this migration?

  1. Microsoft assumes responsibility for operating system patching, and Microsoft remains responsible for physical host security.Cevap
  2. B
    The customer remains responsible for operating system patching, and Microsoft remains responsible for physical host security.
  3. C
    Microsoft assumes responsibility for operating system patching, and the customer assumes responsibility for physical host security.
  4. D
    The customer remains responsible for operating system patching, and the customer assumes responsibility for physical host security.

Cevap

Microsoft assumes responsibility for operating system patching, and Microsoft remains responsible for physical host security.
The correct answer is that Microsoft assumes responsibility for operating system patching, and Microsoft remains responsible for physical host security. Under the Shared Responsibility Model, migrating from an IaaS model (Virtual Machines) to a PaaS model (Azure Blob Storage) shifts the responsibility of operating system patching from the customer to Microsoft. However, the responsibility for securing the physical host resides with Microsoft in all cloud service models.

Adım Adım Çözüm

1
Identify the service models involved in the migration.
The migration shifts the workload from Azure Virtual Machines (Infrastructure as a Service - IaaS) to Azure Blob Storage (Platform as a Service - PaaS).
Identifying the source and target service models is required to analyze how responsibilities partition between the customer and Microsoft.
2
Determine the allocation of operating system patching responsibility before and after migration.
In IaaS, operating system patching is a customer responsibility, whereas in PaaS, Microsoft assumes responsibility for managing and patching the operating system.
Operating system and middleware management shifts to the cloud provider when transitioning from IaaS to PaaS.
3
Determine the allocation of physical host security responsibility before and after migration.
In both IaaS and PaaS models, physical host security remains the sole responsibility of Microsoft.
Physical security of the datacenters, hardware, and infrastructure is managed entirely by the cloud provider across all service types.
