Cloud Interconnect documentation
Cloud Interconnect extends your external network to the Google network through a
high-availability, low-latency connection. You can use Dedicated Interconnect
to connect directly to Google. Alternatively, you can use Partner Interconnect
to connect to Google through a supported service provider. You can use
Cross-Cloud Interconnect to connect to your network that's hosted by another
cloud service provider.
