Question

Difficulty: HardInfrastructure as a Service (IaaS)

Is the following statement true or false? Under the Microsoft Azure Shared Responsibility Model, when deploying a database server inside an Azure Virtual Machine (an Infrastructure as a Service (IaaS) deployment), Microsoft is responsible for maintaining the underlying physical hardware and hypervisor, while the customer is responsible for database configuration, database engine patching, and guest operating system updates.

Answer: Answer

Answer

True
In an Infrastructure as a Service (IaaS) setup, the customer maintains control over the operating system, middleware, and application layers. When running a database on a VM, the customer must manage all aspects of the database installation and the guest OS itself, while Microsoft only manages the physical hosts, network, storage hardware, and virtualization hypervisor.

Step-by-Step Solution

1
Analyze the service model context.
The scenario describes deploying a database inside an Azure Virtual Machine, which represents an Infrastructure as a Service (IaaS) model.
Identifying the correct service model is essential for determining boundaries within the Shared Responsibility Model.
2
Evaluate the infrastructure provider's responsibilities under IaaS.
Under IaaS, Microsoft manages the physical servers, networking, storage hardware, and the hypervisor layer.
The cloud provider always retains responsibility for the physical infrastructure and virtualization layer in IaaS.
3
Evaluate the customer's responsibilities under IaaS.
The customer is responsible for the guest operating system, applications, middleware, and data. This includes patching the guest OS, installing the database engine, and managing database updates.
In an IaaS VM deployment, the customer maintains administrative access and responsibility for all software running inside the virtual machine.
4
Confirm the alignment of the statement with these rules.
The statement correctly states that Microsoft manages physical hardware/hypervisors and the customer manages database configuration, database patching, and guest OS updates.
Comparing the statement's breakdown of responsibilities to the IaaS model confirms the statement is true.
