Cloud Interconnect provides two options for extending your on-premises network to your Google Cloud Platform (GCP) Virtual Private Cloud (VPC) networks. You can create a dedicated connection (Dedicated Interconnect) or use a service provider (Partner Interconnect) to connect to VPC networks. When choosing an interconnect type, consider your connection requirements, such as the connection location and capacity.
- If you have high bandwidth needs, Dedicated Interconnect can be a cost-effective solution.
- If you require a lower-bandwidth solution, Dedicated Interconnect and Partner Interconnect provide a variety of capacity options starting at 50 Mbps.
- If you can't physically meet Google's network in a colocation facility to reach your Virtual Private Cloud networks, you can use Partner Interconnect to connect to a variety of service providers that connect directly to Google.
The following table highlights the key differences between Dedicated and Partner Interconnect.
|Dedicated Interconnect||Partner Interconnect|
|Features||A direct connection to Google. Traffic flows directly between networks, not through the public Internet. 10 Gbps or 100 Gbps circuits with flexible interconnect attachment options from 50 Mbps to 50 Gbps.||More points of connectivity through one of our supported service providers. Traffic between networks flows through a service provider, not through the public Internet.Flexible interconnect attachment options from 50 Mbps to 50 Gbps|
|Set up||Requires routing equipment in a colocation facility that supports the regions that you want to connect to.||Use any supported service provider to connect to Google.|
|BGP configuration||You must configure BGP on your on-premises routers and Cloud Routers.||For layer 2 connections, you must configure BGP on your on-premises routers and Cloud Routers. For layer 3 connections, the configuration of your Cloud Routers and their peers are fully automated.|
|SLA||Google provides an end-to-end SLA for the connection.||Google provides an SLA for the connection between Google and service provider. Whether an end-to-end SLA for the connection is offered, depends on your service provider. Check with them for more information.|
|Pricing||See Dedicated Interconnect Pricing||See Partner Interconnect Pricing Charges also apply to egress traffic from your VPC network to your on-premises network.|
Dedicated Interconnect summary
- Scale to meet the most demanding data needs. Connection capacity is delivered over one or more 10 Gbps or 100 Gbps Ethernet circuits, with a maximum of 8 x 10 Gbps circuits (80 Gbps), or 2 x 100 Gbps (200 Gbps) circuits for each Dedicated Interconnect connection.
- Dedicated Interconnect allows you to scale your costs according to the number and capacity of interconnect attachments (VLANs) you order, with capacities of 50 Mbps to 50 Gbps for each attachment.
- If your traffic doesn't require a 10 Gbps or 100 Gbps circuit, consider Cloud VPN or Partner Interconnect.
- Google offers an end-to-end SLA for the connectivity between your VPC and on-premises networks for Google-defined topologies.
- The connection between your network and Google's network is not encrypted. If you require additional data security, use application-level encryption or your own VPN. Currently, you can't use Google Cloud VPN in combination with Dedicated Interconnect, but you can use your own VPN solution.
Partner Interconnect summary
- Connect to supported service providers, who provide more points of connectivity compared to the colocation facilities available for Dedicated Interconnect.
- Partner Interconnect lets you scale your costs, depending on the number of interconnect attachments (VLANs) you order and their capacities, which start at 50 Mbps with up to 50 Gbps per interconnect attachment.
- Compared to Dedicated Interconnect, you don't need to install and maintain routing equipment in a colocation facility.
- You must work with a supported service provider. If your service provider isn't supported or if you don't want to pass traffic through a service provider, consider Cloud VPN or Dedicated Interconnect.
- Your service provider might provide an end-to-end SLA, based on the Google-defined topologies. For more information, contact your service provider.
- Increases in the number of interconnect attachments (VLANs) or increasing the capacity of an existing attachment depends on your service provider's available capacity.
- Google bills you based on your interconnect attachment's capacity and egress traffic. This doesn't include additional charges by your service provider, who might charge you to carry data across their network.
- The connection between your network and Google's network is not encrypted. If you require additional data security, use application-level encryption or your own VPN. Currently, you can't use Google Cloud VPN in combination with Partner Interconnect, but you can use your own VPN solution.
