Network traffic cost related query

[mpoloq]

Hi Team,

This is my first post so please be understanding 🙂 I am trying to understand the cost associated with a data flow as we have a massive amount of data to be transferred to GCP. In simplified version:

On-prem datacenter -> partner interconnect --- 5 Gbps ---> us-west2 --- VPC peering ---> us-east4 --- load balancer --> VM

1. Partner interconnect. No cost for uploading the data. The only price is related with VLAN attachments. In my case '$1.25 per hour per VLAN attachment' for 5 Gbps

2. Inter-region data transfer. Src North America, Dst North America is 0.02$/GB

3. Load balancer

First 5 forwarding rules $0.028 Per Hour
Inbound data processed by load balancer $0.009 Per GiB
Outbound data processed by load balancer $0.009 Per GiB

Is there any other hidden transfer price which I am missing ?
