Networking: The Global VPC
Page 1 of 1
The Global VPC
Networking is a major differentiator for GCP.
- Global by Default: In AWS or Azure, a VPC (Virtual Network) is tied to a specific Region (e.g., East US). To talk to West US, you need "Peering."
- GCP VPC: A VPC in GCP spans the entire globe. You can have a subnet in
us-east1and a subnet inasia-east1inside the same VPC, and they can talk to each other over private IP addresses automatically, without complex VPNs or peering configurations. This utilizes Google's massive private fiber optic backbone.
