Zorluk: ZorInfrastructure as a Service (IaaS)

A research institute needs to deploy a custom data-processing system that requires a customized Linux kernel configuration and the installation of specialized kernel-level modules. The institute wants to avoid the overhead of procuring, installing, and maintaining physical servers, but must retain full administrative control over the environment.

Which cloud service model must the institute adopt, and which party is responsible for patching the guest operating system?

  1. Infrastructure as a Service (IaaS), and the customer is responsible for patching the guest operating system.Cevap
  2. B
    Infrastructure as a Service (IaaS), and Microsoft is responsible for patching the guest operating system.
  3. C
    Platform as a Service (PaaS), and Microsoft is responsible for patching the guest operating system.
  4. D
    Platform as a Service (PaaS), and the customer is responsible for patching the guest operating system.

Cevap

Infrastructure as a Service (IaaS), and the customer is responsible for patching the guest operating system.
The correct option is the one stating that Infrastructure as a Service (IaaS) is required and the customer is responsible for patching the guest operating system. Kernel customization and specialized module installations require full administrative access to the operating system, which is only provided by IaaS. In the IaaS shared responsibility model, the customer owns and maintains the guest operating system, which includes applying security patches.

Adım Adım Çözüm

1
Analyze the system requirements
The system requires Linux kernel configuration changes and kernel-level modules.
To select the correct cloud service model, we must identify the level of administrative control required over the operating system.
2
Map requirements to cloud service categories
IaaS provides full administrative access to the guest operating system, whereas PaaS and SaaS abstract the operating system layer, preventing kernel modifications.
Only IaaS offers the control needed to configure the kernel and install custom modules.
3
Determine patching responsibility in the selected model
Under the IaaS shared responsibility model, Microsoft manages the physical servers and hypervisor, while the customer is responsible for the guest operating system, including patching.
Applying the shared responsibility matrix identifies who maintains the guest operating system.
