In this page, you learn how to create a private connectivity configuration. This type of configuration contains information that Datastream uses to communicate with a data source over a private network (internally within Google Cloud, or with external sources connected over VPN or Interconnect). This communication happens through a Private Service Connect interface connection or a Virtual Private Cloud (VPC) peering connection.
A Private Service Connect interface connection uses a virtual machine (VM) with a network interface that Datastream creates. The network interface then connects to your VPC network using the network attachment that you supply, with the IP address assigned from the network attachment subnetwork.
A VPC peering connection is a networking connection between two VPCs that lets you route traffic between them using internal, private IPv4 addresses. You need to provide the private IP addresses when setting up the private connectivity configuration because Datastream doesn't support Domain Name System (DNS) resolution in private connections.
