如果您打算创建具有专用 IP 地址的 Cloud Data Fusion 实例，您可以首先使用 VPC Service Controls (VPC-SC) 为实例建立安全边界，从而提供额外的安全保护。
私有 Cloud Data Fusion 实例和其他资源周围的 VPC-SC 安全边界有助于降低数据渗漏的风险。 Google Cloud 例如，使用 VPC Service Controls 时，如果 Cloud Data Fusion 流水线从边界内受支持的资源（如 BigQuery 数据集）读取数据，然后尝试将输出写入边界外的资源，则流水线将失败。
Cloud Data Fusion 资源在两个 API 界面上公开：
datafusion.googleapis.com 控制平面 API 界面，可让您执行实例级操作，例如创建和删除实例。
datafusion.googleusercontent.com 数据平面 API 界面（ Google Cloud 控制台中的 Cloud Data Fusion 网页界面），它在 Cloud Data Fusion 实例上执行以创建和执行数据流水线。
您可以通过同时限制与上述两个 API 界面的连接，来使用 Cloud Data Fusion 设置 VPC Service Controls。
策略：
Cloud Data Fusion 流水线在 Dataproc 集群上执行。
要使用服务边界保护 Dataproc 集群，请按照设置专用连接的说明操作，以允许该集群在边界内正常工作。
如果插件使用的 API 不受 VPC Service Controls 支持，请勿使用这些插件。 Google Cloud
如果您使用了不受支持的插件，Cloud Data Fusion 将阻止 API 调用，从而导致流水线预览和执行失败。
要在 VPC Service Controls 服务边界内使用 Cloud Data Fusion，请添加或配置多个 DNS 条目，以便将以下网域指向受限 VIP（虚拟 IP 地址）：
datafusion.googleapis.com
*.datafusion.googleusercontent.com
*.datafusion.cloud.google.com
限制：
在创建 Cloud Data Fusion 私有实例之前，请先建立 VPC Service Controls 安全边界。不支持对在设置 VPC Service Controls 之前创建的实例进行边界保护。
目前，Cloud Data Fusion 数据层面界面不支持使用基于身份的访问权限来指定访问权限级别。

For example, with\nVPC Service Controls, if a Cloud Data Fusion pipeline reads data\nfrom a [supported resource](/vpc-service-controls/docs/supported-products),\nsuch as a BigQuery dataset, located within the perimeter,\nthen tries to write the output to a resource outside the perimeter, the pipeline\nwill fail.\n\nCloud Data Fusion resources are exposed on two API surfaces:\n\n1. The `datafusion.googleapis.com` control plane API surface, which\n allows you to perform instance-level operations, such as the creation and\n deletion of instances.\n\n2. The `datafusion.googleusercontent.com` data plane API surface (the\n [Cloud Data Fusion Web UI](/data-fusion/docs/concepts/overview#using_the_code-free_web_ui)\n in the Google Cloud console), which executes on a Cloud Data Fusion\n instance to create and execute data pipelines.\n\nYou set up VPC Service Controls with Cloud Data Fusion by\nrestricting connectivity to both of these API surfaces.\n\nStrategies:\n\n- Cloud Data Fusion pipelines are executed on Dataproc clusters.\n To protect a Dataproc cluster with a service perimeter,\n follow the instructions for\n [setting up private connectivity](/vpc-service-controls/docs/set-up-private-connectivity)\n to allow the cluster to function inside the perimeter.\n\n- Don't use plugins that use Google Cloud APIs that are not [supported by\n VPC Service Controls](/vpc-service-controls/docs/supported-products).\n If you use unsupported plugins, Cloud Data Fusion will block the API calls,\n resulting in pipeline preview and execution failure.\n\n- To use Cloud Data Fusion within a VPC Service Controls service\n perimeter, add or configure several DNS entries to point the\n following domains to the restricted VIP (Virtual IP address):\n\n - `datafusion.googleapis.com`\n - `*.datafusion.googleusercontent.com`\n - `*.datafusion.cloud.google.com`\n\nLimitations:\n\n- Establish the VPC Service Controls security perimeter before creating your\n Cloud Data Fusion private instance. Perimeter protection for\n instances created prior to setting up VPC Service Controls is not\n supported.\n\n- Currently, the Cloud Data Fusion data plane UI does not support\n specifying access levels using [identity based access](/access-context-manager/docs/create-basic-access-level#members-example).\n\nRestricting Cloud Data Fusion API surfaces\n------------------------------------------\n\n### Restricting the control plane surface\n\nSee [Setting up private connectivity to Google APIs and services](/vpc-service-controls/docs/set-up-private-connectivity)\nto restrict connectivity to the `datafusion.googleapis.com` API control plane\nsurface.\n\n### Restricting the data plane surface\n\nTo set up private connectivity to the API data plane,\nconfigure DNS by completing the following steps for both the `*.datafusion.googleusercontent.com` and `*.datafusion.cloud.google.com` domains.\n\n1. Create a new private [zone using Cloud DNS](https://console.cloud.google.com/net-services/dns/zones):\n\n 1. Zone type: Check **private**\n 2. Zone name: datafusiongoogleusercontentcom\n 3. DNS name: datafusion.googleusercontent.com\n 4. Network: Select the private IP network you chose when you created your\n Cloud Data Fusion instance.\n\n2. From the [Cloud DNS](https://console.cloud.google.com/net-services/dns/zones) page, click your\n `datafusiongoogleusercontent` DNS zone name to open the\n **Zone details** page. Two records are listed: an NS and an SOA record.\n Use **Add Standard** to add the following two record sets to your\n datafusiongoogleusercontent DNS zone.\n\n 1. Add a CNAME record: In the **Create record set** dialog, fill\n in the following fields to map DNS name `*.datafusion.googleusercontent.com.`\n to the canonical name `datafusion.googleusercontent.com`:\n\n - DNS name: \"\\*.datafusion.googleusercontent.com\"\n - Canonical name: \"datafusion.googleusercontent.com\"\n\n 2. Add an A record: In a new **Create record set** dialog, fill\n in the following fields to map DNS name `datafusion.googleusercontent.com.`\n to IP addresses `199.36.153.4` - `199.36.153.7`:\n\n - DNS name: \".datafusion.googleusercontent.com\"\n - IPv4 address:\n\n - 199.36.153.4\n - 199.36.153.5\n - 199.36.153.6\n - 199.36.153.7\n\n The `datafusiongoogleusercontent` **Zone details** page shows the\n following record sets:\n3.
