Provides direct physical connections between on-premises networks and Google’s networks
Enables transfer of large amount of data between on-premises and GCP
For using it we nee to provision a Cross Connect between on-premises router and Google Network in a common colocation facility
Dedicated Interconnect can be configured to provide a 99.9% or 99.999% SLA
In order to use Dedicated Interconnect, our own network has to physically meet Google’s network in a supported colocation facility
Partner Interconnect
Provides connectivity between on-premises network and Google network through a supported service provider
Recommended if our facility is geographically far away from a colocation facility or if our data transfer requirements don’t warrant a Dedicated Interconnect
Service provider has physical connectivity to GCP which is provided as a service to customers
