Difficulty: MediumAzure Virtual Machines and Azure Virtual Desktop

A company needs to host a legacy accounting application that requires a specific version of Windows Server, custom registry configurations, and the installation of third-party database drivers. The company's IT team must have full administrative access to the operating system to perform these configurations. Which Azure service should the company use to host this application?

  1. Azure Virtual MachinesAnswer
  2. B
    Azure Virtual Desktop
  3. C
    Azure App Service
  4. D
    Azure Container Instances

Answer

Azure Virtual Machines
Azure Virtual Machines is the correct choice because it is an Infrastructure as a Service (IaaS) offering. This gives the customer full administrative access to the guest operating system, allowing the IT team to customize registry settings, install third-party database drivers, and run the specific Windows Server version required by the legacy application.

Step-by-Step Solution

1
Analyze the application requirements.
The application requires a specific version of Windows Server, administrative access to modify the registry, and installation of custom drivers.
This establishes that the solution requires full guest operating system access and control.
2
Compare the management models of the available Azure services.
Azure Virtual Machines is an IaaS offering providing full OS access. Azure App Service and Azure Container Instances are PaaS/serverless offerings with managed OS layers. Azure Virtual Desktop is designed for user client environments.
Matching the administrative requirement to the correct cloud service model ensures the team can configure the OS as needed.

Key Concept

Azure Virtual Machines provides Infrastructure as a Service (IaaS), giving users full control over the operating system, which is required for custom configurations and legacy applications.
