Zorluk: Çok zorShared Responsibility Model

An enterprise is migrating its legacy retail system from Azure Virtual Machines (IaaS) to Azure App Service (PaaS) for the front-end web application and Azure SQL Database (PaaS) for the relational database. Under the Microsoft Azure Shared Responsibility Model, which responsibility transitions from being the sole responsibility of the customer to being managed entirely by Microsoft?

  1. A
    Maintaining the physical security of the server racks, power supplies, and physical hardware hosting the database.
  2. Patching and maintaining the operating systems hosting the application runtime and the database engine.Cevap
  3. C
    Configuring network security rules, database firewalls, and service endpoints to restrict network access.
  4. D
    Managing user database accounts, application-level permissions, and resource identity directories.

Cevap

Patching and maintaining the operating systems hosting the application runtime and the database engine transitions from the customer to Microsoft.
The correct option stating that patching and maintaining the operating systems transitions to Microsoft is correct. In IaaS (Virtual Machines), the customer has full control and administrative responsibility over the guest operating system, including applying patches. When migrating to PaaS (Azure App Service and Azure SQL Database), Microsoft abstracts the operating system layer, meaning they take over all maintenance, patching, and OS-level security updates.

Adım Adım Çözüm

1
Identify the baseline of responsibilities for Azure Virtual Machines (IaaS).
The customer is responsible for the operating system, middleware, and applications, while Microsoft is responsible for physical infrastructure.
This establishes what the customer was responsible for before the migration.
2
Identify the target responsibilities for Azure App Service and Azure SQL Database (PaaS).
Microsoft manages the physical infrastructure, operating system, and runtime/database engine, while the customer manages applications, network firewalls, and identity/data.
This determines the new distribution of responsibilities post-migration.
3
Compare the change in responsibilities to find which one shifted from the customer to Microsoft.
Operating system patching, which was a customer responsibility under IaaS, becomes Microsoft's responsibility under PaaS.
This identifies the correct boundary transition.

Anahtar Kavram
