Creating a Virtual Private Cloud with Subnets

VPCs are software versions of physical networks that link resources in a project. GCP automatically creates a VPC when you create a project. You can create additional VPCs and modify the VPCs created by GCP.

VPCs are global resources, so they are not tied to a specific region or zone. Resources, such as Compute Engine virtual machines (VMs) and Kubernetes Engine clusters, can communicate with each other, assuming traffic is not blocked by a firewall rule.

VPCs contain subnetworks, call subnets, which are regional resources. Subnets have a range of IP addresses associated with them. Subnets provide private internal addresses. Resources use these addresses to communicate with each other and with Google APIs and services.

In addition to VPCs associated with projects, you can create a shared VPC within an organization. The shared VPC is hosted in a common project. Users in other projects who have sufficient permissions can create resources in...
