An organization runs a database system on an Azure Virtual Machine (IaaS). To reduce administrative overhead, they plan to migrate the database to Azure SQL Database (PaaS). Which statement correctly describes how the responsibility for operating system patching shifts after this migration?
- Microsoft becomes fully responsible for operating system patching, which was previously the organization's responsibility.Cevap
- BThe organization remains responsible for operating system patching, but Microsoft manages the database engine updates.
- CThe responsibility for operating system patching is shared, where the organization patches the guest operating system and Microsoft patches the host operating system.
- DMicrosoft becomes responsible for database configuration, while the organization retains responsibility for the underlying operating system.
Cevap
Microsoft becomes fully responsible for operating system patching, which was previously the organization's responsibility.
In the Shared Responsibility Model, migrating from Infrastructure as a Service (IaaS) to Platform as a Service (PaaS) shifts the responsibility of managing the operating system from the customer to Microsoft. When using Azure Virtual Machines (IaaS), the customer is responsible for maintaining and patching the guest operating system. When migrating to Azure SQL Database (PaaS), Microsoft handles all underlying infrastructure maintenance, including operating system patching and updates.
