Zorluk: OrtaInfrastructure as a Service (IaaS)

An online education startup is planning to host its main learning management application on Azure. The application's web tier requires custom modifications to the web server's underlying operating system registry settings and custom firewall rules that cannot be configured on a fully managed platform. Which cloud service model should the startup choose for the web tier?

  1. A
    Platform as a Service (PaaS)
  2. Infrastructure as a Service (IaaS)Cevap
  3. C
    Software as a Service (SaaS)
  4. D
    Hybrid Cloud

Cevap

Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) is the correct choice because it provides the customer with virtual machines, giving them full control over the guest operating system, including the ability to configure custom registry settings and OS-level firewall rules.

Adım Adım Çözüm

1
Analyze the requirement for OS-level custom registry modifications and custom firewall configurations.
Identify that these tasks require administrative control over the guest operating system.
Determining the level of control helps classify the required cloud service model.
2
Compare the cloud service categories based on the shared responsibility model.
Determine that Infrastructure as a Service (IaaS) provides virtual machines where the customer is responsible for and has access to the guest operating system.
This directly addresses the requirement for OS-level customization, as PaaS and SaaS abstract the OS layer from the customer.
