- Cloud Interconnect provides low latency, highly available connections that enable users to reliably transfer data between on-premises and Virtual Private Cloud networks.
- Cloud Interconnect connections provide RFC 1918 communication, which means internal (private) IP addresses are directly accessible from both networks.
- Cloud Interconnect offers two options for extending the on-premises network.
- Dedicated Interconnect provides a direct physical connection between on-premises network and Google's network.
- Partner Interconnect provides connectivity between on-premises and Google Cloud VPC networks through a supported service provider.
- Dedicated Interconnect provides direct physical connections between on-premises network and Google’s network.
- Dedicated Interconnect enables the transfer of large amounts of data between networks, which can be more cost effective than purchasing additional bandwidth over the public Internet.
- The network must physically meet Google's network in a colocation facility.
- Users must provide their own routing equipment.
- For Dedicated Interconnect, provision a cross connect between the Google network and the customer router in a common location.
- This cross connect is a Dedicated Interconnect connection.
- To exchange routes, a BGP session is configured over the interconnect between the Cloud Router and on-premises router.
- Then, traffic from the on-premises network can reach the VPC network and vice versa.
- Partner Interconnect provides connectivity between on-premises network and VPC network through a supported service provider.
- A Partner Interconnect connection is useful if the data center is in a physical location that can't reach a Dedicated Interconnect colocation facility or if data needs don't warrant an entire 10 Gbps connection.
- Partner Interconnect requires users to separately obtain services from a third-party network service provider.
- Google is not responsible for any aspects of Partner Interconnect provided by the third-party service provider nor any issues outside of Google's network.
- Customers must work with a supported service provider to establish connectivity between their network and on-premises network.
