Question

Difficulty: MediumInfrastructure as a Service (IaaS)

A healthcare provider plans to migrate a legacy health records application to Azure. The application requires direct access to the underlying operating system to configure custom registry keys and install kernel-level system drivers. To meet these requirements, the provider should deploy the application using Platform as a Service (PaaS) rather than Infrastructure as a Service (IaaS). Is this statement true or false?

Answer: Answer

Answer

False
The statement is false because Infrastructure as a Service (IaaS) is the cloud service model that provides administrative access to the underlying operating system. Platform as a Service (PaaS) abstracts the operating system layer, preventing customers from installing custom kernel-level drivers or making registry modifications.

Step-by-Step Solution

1
Analyze the application requirements.
The application requires direct operating system access for custom registry configurations and kernel-level drivers.
Identifying the required level of control over the infrastructure is necessary to select the correct cloud service model.
2
Compare the access levels of IaaS and PaaS.
IaaS (e.g., Azure VMs) provides full administrative control over the OS, while PaaS abstracts and manages the OS, restricting customer access.
Understanding the division of responsibility and access limits between the two models determines which one supports custom OS configurations.
3
Evaluate the statement.
The statement recommends PaaS instead of IaaS, which contradicts the required operating system access.
Since IaaS is required for OS-level configurations, recommending PaaS makes the statement false.
