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 spokes) | $0.10 per hour |
Data transfer
Data transfer refers to any traffic that flows between a set of hybrid spokes connected to Network Connectivity Center.
Network Connectivity Center data transfer traffic is different from data transfer in and data transfer out, which flows either into or out of Google's network. In contrast, Network Connectivity Center data transfer can be both: it can flow into and out of Google's network, because it is traffic that is exchanged between any two hybrid spokes.
Data transfer charges are based on gibibytes (GiB) of traffic per month.
Advanced Data Networking
Advanced Data Networking (ADN) refers to the processing fee charged for all traffic that is sent from a spoke through a hub.
The ADN charge is $0.02 per Gibibyte (GiB) per month.
This charge currently applies for traffic between VPC spokes. ADN charges for hybrid spokes are currently waived.
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.
Each month, VPC-1 sends 10 TiB of data to VPC-2, and VPC-2 sends 5 TiB of data to VPC-1.
The following table describes the charges for one 30-day month.
| Resources | Usage | Formula | Estimated monthly cost |
|---|---|---|---|
|
Spoke hour charges |
2 spokes | 2 x 24 hours x 30 days at $0.10 | $144 |
|
Advanced Data Networking charges |
10 TiB of data 5 TiB of data |
10 TiB (10 * 1024 GiB = 10,240 GiB) at $0.02 per GiB 5 TiB (5 *1024 GiB = 5120 GiB) at $0.02 per GiB |
$204.80 + $102.40 |
| Total cost | 15 TiB of data |
$451.20 |
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.
The following table describes the charges for one 30-day month.
| Resources | Usage | Formula | Estimated monthly cost |
|---|---|---|---|
|
Spoke hour charges |
2 spokes | 2 x 24 hours x 30 days at $0.075 | $108.00 |
|
Data transfer charges |
5 TiB of data transferred 5 TiB of data transferred Total: 10 TiB between one unique site pair. |
5 TiB (5 * 1,024 GiB = 5,120 GiB) at $0.11 per GiB 5 TiB (5 * 1,024 GiB = 5,120 GiB) at $0.11 per GiB |
$563.20 $563.20 |
|
Advanced Data Networking |
10 TiB of data |
10 TiB (10 * 1,024 GiB = 10,240 GiB) at $0.02 per GiB |
$204.80 Currently waived |
| Total cost |
$1,234.40 |
