VPC Network
Definition
Google Cloud's implementation of Virtual Private Cloud, providing global-by-default networking that spans all regions for secure connectivity.
Use Cases
- Spotify: Run microservices across multiple regions for resilience and low-latency user access. — Spotify has publicly discussed running services on Google Cloud. In a typical Google Cloud design, teams use a single VPC network with multiple regional subnets (for example, one subnet per region) and control traffic with VPC firewall rules and Cloud Load Balancing. Private connectivity between services is maintained using internal IPs and shared routing within the VPC. (Improved availability and operational consistency by using one network construct across regions, reducing the need for separate per-region network duplication.)
- Snap Inc.: Support large-scale, latency-sensitive backend services with regional expansion. — Snap has publicly shared its use of Google Cloud for infrastructure. A common approach is to place Compute Engine or GKE workloads in multiple regions while keeping consistent IP planning, routing, and security controls within a single global VPC network, using regional subnets and centralized firewall policy management. (Faster regional rollout and simpler network governance by applying consistent networking patterns across regions.)
- The Home Depot: Modernize enterprise applications and connect cloud workloads to on-premises networks. — The Home Depot has publicly discussed using Google Cloud. A typical enterprise implementation uses a VPC network as the hub for cloud workloads, with private connectivity to on-premises via Cloud VPN or Cloud Interconnect, and segmented subnets for different environments (dev/test/prod) and application tiers. (More secure hybrid connectivity and clearer network segmentation, supporting modernization while maintaining enterprise controls.)

Frequently Asked Questions
- What's the difference between a Google Cloud VPC network and a subnet?
- A VPC network is the top-level private network container (routing, firewall rules, and connectivity). A subnet is a regional IP range inside that VPC where you place resources like VM instances. In Google Cloud, one VPC network can have multiple subnets in different regions.
- When should I use a VPC network in Google Cloud?
- Use a VPC network whenever you need private IP networking for Google Cloud resources (VMs, GKE nodes, managed services with private access), want to control traffic with firewall rules and routes, or need hybrid connectivity to on-premises. It’s especially useful for multi-region designs because the same VPC can include subnets in multiple regions.
- How much does a Google Cloud VPC network cost?
- Creating and using a VPC network itself does not have a standalone hourly charge. Costs typically come from what you attach to it and how you use it, such as egress traffic (internet or inter-region), Cloud NAT, Cloud VPN or Cloud Interconnect, load balancers, and any compute resources. Inter-region traffic within Google Cloud can incur charges depending on the traffic path and services used.
