Google Cloud's implementation of Virtual Private Cloud, providing global-by-default networking that spans all regions. Unlike AWS VPCs which are regional, GCP VPC Networks can have subnets in different regions within the same network. Equivalent to AWS VPC, Azure VNet, and OCI VCN.
A VPC Network in Google Cloud connects Compute Engine instances in us-east1 and europe-west1 within the same network, simplifying multi-region architectures.
All provide logically isolated virtual networks for cloud resources (subnets, routing, firewalling). A key difference is scope: Google Cloud VPC networks are global resources (subnets are regional but can exist in multiple regions within one VPC), while AWS VPCs and Azure VNets are regional constructs (you typically connect regions using peering, gateways, or WAN services). OCI VCNs are regional.
