Zorluk: OrtaInfrastructure as a Service (IaaS)

A software development company is setting up a testing environment in Azure. They need to deploy virtual machines running various versions of Windows Server and Linux to test their software's compatibility across different operating systems. They require full administrative access to install custom libraries and configure the system registry. Under the Azure shared responsibility model, which of the following tasks is the responsibility of Microsoft for this environment?

  1. Ensuring the availability and maintenance of the underlying physical servers and hypervisors.Cevap
  2. B
    Managing and patching the database engines and runtime libraries deployed within the virtual machines.
  3. C
    Automatically updating and patching the guest operating systems to keep the test environment secure.
  4. D
    Managing the application software lifecycle and access configurations for the end users.

Cevap

Ensuring the availability and maintenance of the underlying physical servers and hypervisors.
Ensuring the availability and maintenance of the underlying physical servers and hypervisors is correct. Under the shared responsibility model for Infrastructure as a Service, the cloud provider (Microsoft) is responsible for the physical security of datacenters, the physical network, the host hardware, and the hypervisor layer that runs the virtual machines.

Adım Adım Çözüm

1
Determine the cloud service category for the scenario.
Infrastructure as a Service (IaaS) is identified because the environment relies on virtual machines where the customer has full access to the operating system, registry, and installed libraries.
Before assigning responsibilities, the correct service model must be identified since responsibility boundaries shift between IaaS, PaaS, and SaaS.
2
Differentiate responsibilities between the customer and the cloud provider in IaaS.
The customer is responsible for everything from the operating system upward (including patches, configuration, runtimes, and application data). Microsoft is responsible for everything below the operating system layer.
This division defines who manages the virtualized operating system versus the physical hosting environment.
3
Map the specific responsibilities of Microsoft to the options.
Microsoft manages the physical servers, networking hardware, and the virtualization layer (hypervisor). The option regarding physical server and hypervisor maintenance matches this definition.
Selecting the correct task requires finding the one that belongs to the physical/virtualization infrastructure managed by the cloud provider.
