Zorluk: OrtaInfrastructure as a Service (IaaS)

An enterprise plans to migrate its legacy line-of-business application to Azure. The application requires direct access to the local file system of the operating system and runs on a specific, non-standard port that must be opened at the operating system firewall level. Which cloud service model should the enterprise use to host this application, and who is responsible for managing the operating system firewall settings?

  1. A
    Infrastructure as a Service (IaaS), and Microsoft is responsible
  2. B
    Platform as a Service (PaaS), and Microsoft is responsible
  3. Infrastructure as a Service (IaaS), and the customer is responsibleCevap
  4. D
    Platform as a Service (PaaS), and the customer is responsible

Cevap

Infrastructure as a Service (IaaS), and the customer is responsible
The correct option is the one stating Infrastructure as a Service (IaaS) and that the customer is responsible. Under the shared responsibility model, IaaS gives the customer full administrative access to the virtual machine's operating system, allowing them to configure custom firewall ports and access local files. Consequently, the customer is responsible for configuring, updating, and securing this guest operating system, including its local firewall.

Adım Adım Çözüm

1
Analyze the application requirements
The application requires direct access to the operating system file system and custom OS firewall rules.
This determines which cloud service model is appropriate since PaaS models abstract the operating system level.
2
Identify the correct cloud service model
Infrastructure as a Service (IaaS) is the only model that provides direct access to the guest operating system.
IaaS provides virtual machines where the customer has full administrative control over the OS.
3
Determine responsibility for operating system firewall settings under IaaS
Under the shared responsibility model for IaaS, the customer is responsible for the guest operating system, including its firewall configurations.
Microsoft's responsibility in IaaS ends at the hypervisor level.
