Virtual Private Cloud (VPC) Peering

Establish communication between GCP VPCs via VPC peering

Virtual Private Cloud (VPC) peering establishes a direct networking connection between two VPCs, allowing traffic to flow seamlessly between them. With VPC peering, resources in the connected VPCs can communicate as though they are part of the same network, even if the VPCs reside in different regions (referred to as Inter-Region VPC peering).

This connection is ideal for facilitating data transfer between environments. For instance, if you manage multiple GCP projects, you can peer the VPCs across those projects to enable secure communication and resource sharing, such as setting up a file-sharing network.
