This document describes pricing for Network Connectivity Center.
Network Connectivity Center is a hub-and-spoke model for network connectivity management in Google Cloud. With this model, virtual private cloud networks and on-premises networks connect to a Network Connectivity Center hub by using spokes that have supported Google Cloud spoke resources attached to them.
For more information about Network Connectivity Center, see the Network Connectivity Center overview.
Current pricing
The following sections describe the current pricing for Network Connectivity Center.
Hubs and spokes
The following table describes charges for hubs and spokes. Spoke hours refers to the number of hours within a month that a spoke is active.
Spoke hour charges are waived for up to three VPN spokes and three Cloud Interconnect spokes.
| Resource | Price |
|---|---|
| Hub | No charge |
| Spoke hours (Cloud Interconnect, Cloud VPN and Cloud Router appliance spokes) | $0.075 per hour |
| Spoke hours (VPC and producer VPC spokes) | $0.10 per hour |
Advanced Data Networking
Advanced Data Networking (ADN) refers to the data processing fee charged for all traffic that is sent from a spoke through a hub. Charges are attributed to the spoke project that originates the traffic.
The ADN charge is $0.02 per Gibibyte (GiB) per month.
This charge applies for traffic originating from VPC spokes. Traffic that is sent within a VPC network does not incur ADN. ADN charges for traffic originating from hybrid spokes are currently waived. Hybrid spokes are of type Cloud Interconnect, Cloud VPN or Router Appliance.
Data transfer
Site-to-site data transfer refers to any traffic sent from one hybrid endpoint (VPN, Interconnect VLAN attachment, or Router Appliance) to another hybrid endpoint in a different supported cloud region.
These charges apply even if the hybrid endpoint happens to be connected to another network or project in Google Cloud and doesn't actually leave Google's network; for example, if a VPN tunnel connects to another VPC in Google cloud, traffic from that VPN to an Interconnect VLAN attachment is still considered site-to-site data transfer.
We recommend connecting hybrid endpoints together using Network Connectivity Center (NCC), but note that these charges apply even if NCC isn't used. For example, if static routes are configured to send traffic from one hybrid endpoint to another hybrid endpoint then that traffic would still be billed as site-to-site data transfer.
Data transfer charges are based on gibibytes (GiB) of traffic per month.
Pricing example
Advanced Data Networking
In this example, an enterprise has two Virtual Private Cloud (VPC) global networks, VPC-1 and VPC-2, which it connects via VPC spokes to their Network Connectivity Center hub. Each VPC is in its own project distinct from the hub project. Additionally, there is also a Cloud Interconnect (IC-1) spoke connected to the same hub for on-premise network access.
Each month, VPC-1 sends 10 TiB of data to VPC-2, and VPC-2 sends 5 TiB of data to VPC-1. Each VPC-1 and VPC-2 also send an additional 1 TiB of data to the IC-1 spoke over the same period.
The following table describes the charges for one 30-day month.

$204.80 + $102.40 + $20.48 + $20.48 |
| Total cost | 17 TiB of data |
$546.16 |
Note that both the Spoke hour charges and Advanced Data Networking charges for VPC spokes accrue in their respective projects.
Data transfer
In this example, an enterprise connects two Router appliance spokes to their Network Connectivity Center
hub. One spoke represents an office in Los Angeles (us-west2). Another represents an
office in Mumbai (asia-south1).
Every month, the US office transfers 5 TiB of data to the Asia office, and the Asia office transfers 5 TiB to the US office.

Pricing for other Google Cloud resources
The pricing on this page does not include charges for other Google Cloud resources and products that you might be using in conjunction with Network Connectivity Center. For example:
- If you use Router appliance spokes, you pay for the underlying Compute Engine resources.
- If you use VLAN attachment spokes, you pay for the underlying Cloud Interconnect resources.
- If you use VPN spokes, you pay for the underlying Cloud VPN resources.
