How should the team pair each administrative task with its corresponding responsibility classification?

  • Patching the guest operating system for an Azure Virtual Machine (IaaS)A responsibility that remains solely with the customer
  • Upgrading the database engine software for Azure SQL Database (PaaS)A responsibility shifted to Microsoft
  • Configuring identity and access management for Microsoft 365 (SaaS)A customer responsibility even in a fully managed SaaS solution

Cevap

Patching the guest operating system for an Azure Virtual Machine (IaaS) matches with a responsibility that remains solely with the customer. Upgrading the database engine software for Azure SQL Database (PaaS) matches with a responsibility shifted to Microsoft. Configuring identity and access management for Microsoft 365 (SaaS) matches with a customer responsibility even in a fully managed SaaS solution.
Patching the guest operating system of an Azure Virtual Machine is a customer responsibility because IaaS leaves OS control to the user. Upgrading database engine software for Azure SQL Database is Microsoft's responsibility since PaaS abstracts platform management. Configuring identity and access management for Microsoft 365 is the customer's responsibility because user access and identities are always managed by the customer regardless of the cloud model.

Adım Adım Çözüm

1

Patching a guest OS on an Azure Virtual Machine (IaaS) is identified as a customer duty, because IaaS gives the customer control over the operating system.
To determine ownership of operating system maintenance in Infrastructure as a Service.
2
Analyze the database service task
Upgrading the database engine for Azure SQL Database (PaaS) is identified as a Microsoft duty, as PaaS removes the platform maintenance burden from the customer.
To determine ownership of database platform management in Platform as a Service.
3
Analyze the SaaS application task
Configuring identity and access policies for Microsoft 365 (SaaS) is identified as a customer duty, as user access control is never transferred to the cloud provider.
To determine ownership of identity and access management in Software as a Service.

Anahtar Kavram

Under the Azure Shared Responsibility Model, physical infrastructure management shifts to Microsoft, while data, endpoints, accounts, and access management always remain the responsibility of the customer. Responsibility for applications, network controls, and operating systems shifts between Microsoft and the customer depending on the service model (IaaS, PaaS, or SaaS).
