Network Connectivity is Google's suite of products that provide enterprise connectivity from your on-premises network or from another cloud provider to your Virtual Private Cloud (VPC) network.
Securely extends your peer network to Google's network through an IPsec VPN tunnel.
Extends your on-premises network to Google's network through a highly available, low latency connection. You can use Dedicated Interconnect to connect directly to Google, or use Partner Interconnect to connect to Google through a supported service provider.
Uses the Border Gateway Protocol (BGP) to dynamically exchange routes between your VPC network and on-premises networks when you use Cloud VPN or Cloud Interconnect.
