The role of service providers to establish private connectivity between on-premises networks and
Google Cloud resources is to facilitate direct, dedicated network connections through Google Cloud
Interconnect. Google Cloud Interconnect is a service that allows customers to connect their on-
premises networks to Google Cloud through a service provider partner. This provides low latency,
high bandwidth, and secure connectivity to Google Cloud services, such as Google Compute Engine,
Google Cloud Storage, and Google BigQuery. Google Cloud Interconnect also supports hybrid cloud
scenarios, such as extending on-premises networks to Google Cloud regions, or connecting multiple
Google Cloud regions together. Google Cloud Interconnect offers two types of connections:
Dedicated Interconnect and Partner Interconnect. Dedicated Interconnect provides physical
connections between the customer’s network and Google’s network at a Google Cloud Interconnect
location. Partner Interconnect provides virtual connections between the customer’s network and
Google’s network through a supported service provider partner. Both types of connections use VLAN
attachments to establish private connectivity to Google Cloud Virtual Private Cloud (VPC)
networks. Reference:
