Optimizing GCP Networking: Solutions for Non - Transitive VPC Peering

Tom Jose Kalapura

Abstract: The PSA (Private Service Access) connection in GCP allows direct communication between a VPC subnet and Google - managed services over a dedicated subnet within the same VPC. When VPC Peering is involved, communication between the PSA subnet and other subnets in a peered VPC is constrained due to the non - transitive nature of GCP VPC peering. This technical report explores a solution to this limitation, focusing on a Regional Internal TCP Proxy Network Load Balancer combined with hybrid connectivity via Network Endpoint Groups (NEGs). This approach enables seamless traffic routing between peered and non - peered environments, enhancing scalability and operational efficiency in hybrid cloud architectures.
