タイトルが何言ってるのかよく分かりませんが要するに VM とか１個ずつじゃなくてまとめてデプロイしたいってことです。

環境

Windows 10 Enterprise
PowerShell 5.1

使い方

１つだけデプロイする場合
- deploy.ps1 と template.json と parameters.json を同一フォルダーに配置して deploy.ps1 を実行
複数デプロイする場合
- deploy.ps1 と template.json を配置したフォルダーに parameters フォルダーを作成して、parameters フォルダー配下にデプロイしたいパラメーターを記述した json ファイルを配置
- または、deploy.ps1 と template.json を配置したフォルダーにパラメーターを記載した json ファイルを複数記載して、 -parametersFilePaths で指定

デプロイ用スクリプト

deploy.ps1 はこんな感じになります。

deploy.ps1

<#
 .SYNOPSIS
    Deploys a template to Azure

 .DESCRIPTION
    Deploys an Azure Resource Manager template

 .PARAMETER subscriptionId
    The subscription id where the template will be deployed.

 .PARAMETER resourceGroupName
    The resource group where the template will be deployed. Can be the name of an existing or a new resource group.

 .PARAMETER resourceGroupLocation
    Optional, a resource group location. If specified, will try to create a new resource group in this location. If not specified, assumes resource group is existing.

 .PARAMETER deploymentName
    The deployment name.

 .PARAMETER templateFilePath
    Optional, path to the template file. Defaults to template.json.

 .PARAMETER parametersFilePaths
    Optional, path to the parameters files. Defaults to parameters.json. If file is not found, will prompt for parameter values based on template.
 
 .PARAMETER parametersDirectoryPath
    Optional, path to the directory which has parameters files. Defaults to parameters.

各ファイルを以下のように配置します。

deploy.ps1
template.json
parameters（フォルダー）

スクリプトを実行すると、仮想マシン web と db が順番にデプロイされました。
