GCP - Billing

What is "NA-based Storage Data Transfer Out via peered/interconnect network"?

"NA-based Storage Data Transfer Out via peered/interconnect network" is a specific billing line item on Google Cloud Platform that refers to the cost of egress traffic from your Cloud Storage buckets located in North America. This data is leaving the Google network via a private, high-speed connection you have established, rather than over the public internet.

This charge is a cost optimization strategy, as the egress costs are significantly lower for data transferred over a dedicated interconnect or a peered network compared to data transferred over the standard internet.
