本文以示例方式演示如何使用专用终结点和区域 VNet 集成通过以下 terraform 配置安全地连接两个 Web 应用（前端和后端）：
- 部署 VNet
- 为集成创建第一个子网
- 为专用终结点创建第二个子网，必须设置特定参数才能禁用网络策略
- 部署一个应用服务计划，类型为 Basic、Standard、PremiumV2、IsolatedV2、Functions 高级（有时称为弹性高级计划），这是专用终结点功能所需的
- 使用特定应用设置创建前端 Web 应用以使用专用 DNS 区域，详细信息
- 将前端 Web 应用连接到集成子网
- 创建后端 Web 应用
- 创建 DNS 专用区域，使用 Web 应用的专用链接区域的名称 privatelink.chinacloudsites.cn
- 将此区域链接到 VNet
- 在终结点子网中为后端 Web 应用创建专用终结点，并在之前创建的 DNS 专用区域中注册 DNS 名称（网站和 SCM）
