This communication happens through a\n*Private Service Connect interface* connection or a\n*Virtual Private Cloud (VPC) peering* connection.\n\nA **Private Service Connect interface** connection uses a virtual\nmachine (VM) with a network interface that Datastream creates.\nThe network interface then connects to your VPC network using the network\nattachment that you supply, with the IP address assigned from the network\nattachment subnetwork.\n\nA **VPC peering** connection is a networking connection between two VPCs that\nlets you route traffic between them using internal, private IPv4 addresses. You\nneed to provide the private IP addresses when setting up the private connectivity\nconfiguration because Datastream doesn't support Domain Name System\n(DNS) resolution in private connections.\n| Datastream automatically deletes private connectivity configurations that haven't been used for a period of six consecutive months. To retain your private connectivity configurations, make sure they are used in at least one active connection profile.\n\nBefore you begin\n----------------\n\nBefore you create your private connectivity configuration, review the\nprerequisites:\n\n- For VPC peering, see [VPC peering prerequisites](/datastream/docs/vpc-peering#vpc-prereqs).\n- For Shared VPC, see [Shared VPC prerequisites](/datastream/docs/vpc-peering#shared-vpc).\n- For Private Service Connect interfaces, see [Private Service Connect prerequisites](/datastream/docs/psc-interfaces#psci-prereqs).\n\nCreate the configuration\n------------------------\n\nTo create a private connectivity configuration, perform the following steps:\n\n1. Go to the **Private connectivity configurations** page in the Google Cloud console.\n\n [Go to the Private connectivity configurations page](https://console.cloud.google.com/datastream/private-connections)\n2. Click **Create configuration**.\n\n3. Use the following table to populate the fields of the\n **Configure private connectivity** section of the\n **Create private connectivity configuration** page:\n\n4. In the **Set up connection** section, select an option from the\n **Private connectivity method** drop-down:\n\n - **PSC interfaces** : select this option to use Private Service Connect interface as your private connectivity method:\n\n - **VPC peering** : select this option to use VPC peering as your private connectivity method:\n\n5. Click **CREATE**.\n\n | It takes a few minutes for your private connectivity configuration to be created. Background resources need to be created so that the configuration can be created.\n\nAfter creating a private connectivity configuration, you can\n[view high-level and detailed information](/datastream/docs/view-a-private-connectivity-configuration)\nabout it.\n\nWhat's next\n-----------\n\n- Learn how to [view your private connectivity configuration](/datastream/docs/create-a-private-connectivity-configuration).\n- Find out how to [delete a private connectivity configuration](/datastream/docs/delete-a-private-connectivity-configuration).\n- Learn about the [Private Service Connect interfaces](/datastream/docs/psc-interfaces) private connectivity method.\n- Learn about the [VPC peering](/datastream/docs/vpc-peering) private connectivity method."]]
