For more information, see [Access control](/data-fusion/docs/access-control).\n- Cloud Data Fusion instances run as the [Compute Engine\n default service account](/compute/docs/access/service-accounts#compute_engine_default_service_account). For information about the types and roles available, see [Service accounts](/iam/docs/service-account-types#google-managed_service_accounts).\n- By default, Cloud Data Fusion executes pipelines using a Dataproc cluster in your project. Ensure that your project meets the [Dataproc networking requirements](/dataproc/docs/concepts/configuring-clusters/network).\n- New projects start with a [default network](/vpc/docs/vpc#default-network). The default network is pre-populated with a firewall rule [default-allow-ssh](/vpc/docs/firewalls#more_rules_default_vpc), that allows incoming connections on TCP port 22 from any source to any instance in the network. In versions earlier than 6.2.0, if this rule to allow ingress on TCP port 22 doesn't exist in the network used by your Cloud Data Fusion instance, you must [create this rule](/vpc/docs/using-firewalls#creating_firewall_rules).\n\nCreate an instance\n------------------\n\n**Caution:** After you create a Cloud Data Fusion instance, you cannot change its edition. \n\n### Console\n\nIf the [API is enabled](/data-fusion/docs/how-to/enable-service), the\nCloud Data Fusion section in the Google Cloud console shows an\n**Instances** page, where you can create and manage your\nCloud Data Fusion instances.\n\n1. In the console, go to the Cloud Data Fusion page.\n2. Click **Instances** , and then click **Create an instance** .\n\n [Create an instance](https://console.cloud.google.com/data-fusion/instance-create)\n3. Enter an **Instance name**.\n4. Enter a **Description** for your instance.\n5. Specify the **Region** in which to create the instance.\n6. Specify the Cloud Data Fusion [**Version**](/data-fusion/docs/release-notes).\n7. Select an [**Edition**](/data-fusion/pricing). The default is **Basic**.\n8. Optional: Click **Add accelerators** to select accelerators to use in your instance.\n9. Specify the [**Dataproc service account**](/dataproc/docs/concepts/configuring-clusters/service-accounts) to use for running your Cloud Data Fusion pipeline in Dataproc. The default is the Compute Engine account. Regardless of version, make sure that a service account has appropriate Identity and Access Management roles for your needs. For more information, see [Granting service account user permission](/data-fusion/docs/how-to/granting-service-account-permission).\n10. Optional: Specify any advanced options. If you don't specify anything,\n the following defaults are used:\n\n11. Click **Create**. It takes up to 30 minutes for the instance\n creation process to complete.\n\nWhile Cloud Data Fusion creates your instance, a progress\nwheel displays next to the instance name on the **Instances** page. After\ncompletion, it turns into a green check mark and indicates that you can\nstart using the instance.\n| After you create an instance, you cannot add or remove the options for [Cloud Logging and Cloud Monitoring](/data-fusion/docs/how-to/viewing-stackdriver-logs#enabling-stackdriver) or [Private IP](/data-fusion/docs/how-to/create-private-ip). To update these options with the Cloud Data Fusion API, call the [`PATCH`](/data-fusion/docs/reference/rest/v1/projects.locations.instances/patch) method.\n\n### API\n\nCreate an instance:\n\nTo create a Cloud Data Fusion instance with the\n[Cloud Data Fusion REST API](/data-fusion/docs/reference/rest),\nconstruct an\n[`instances.create`](/data-fusion/docs/reference/rest/v1/projects.locations.instances/create)\nAPI request, filling in the\n[`Instance`](/data-fusion/docs/reference/rest/v1/projects.locations.instances#Instance)\nresource with your configuration information.\n\nWhat's next\n-----------\n\n- Learn more about [Cloud Data Fusion](/data-fusion/docs/concepts/overview).\n- Work through a [tutorial](/data-fusion/docs/tutorials/targeting-campaign-pipeline)."]]
