            The Azure subscription Id where resources will be created.

        .PARAMETER ResourceGroupName
            The Azure resource group name where the Azure virtual machine will be created.

        .PARAMETER ManagedImageName
            The name of the managed image to be used to create the virtual machine.

        .PARAMETER VirtualMachineName
            The name of the virtual machine to be generated.

        .PARAMETER AdminUserName
            The administrator username for the virtual machine to be created.

        .PARAMETER AdminPassword
            The administrator password for the virtual machine to be created.

        .PARAMETER AzureLocation
            The location where the Azure virtual machine will be provisioned. Example: "eastus"
