What is Google Cloud Virtual Network
Google Cloud Virtual Network (Virtual Private Cloud, VPC) is a software-defined networking service for creating isolated, configurable networks for workloads running on Google Cloud. It is used by cloud infrastructure and platform teams to segment environments, control routing and connectivity, and apply network security policies across projects and regions. The service supports global VPC networks, shared VPC for multi-project architectures, and integration with Google Cloud networking and security services such as Cloud VPN, Cloud Interconnect, and firewall policies.
Global VPC network model
VPC networks can span multiple regions, which simplifies building multi-region architectures without stitching together separate regional networks. Subnets are regional, but the VPC itself is global, enabling consistent routing and policy patterns across regions. This model can reduce operational overhead for organizations standardizing network design across a large footprint.
Strong segmentation and governance
Shared VPC enables central network administration while allowing application teams to deploy resources into controlled subnets across multiple projects. Hierarchical firewall policies and organization-level controls support consistent enforcement across environments. These capabilities help enterprises implement separation of duties and standardized network guardrails.
Broad connectivity options
The platform integrates with Cloud VPN and Cloud Interconnect for private connectivity to on-premises and other environments. It also supports peering and routing features used to connect services across projects and networks. This breadth helps teams implement hybrid connectivity patterns without relying solely on public internet paths.
Complexity at scale
Designing and operating VPCs with multiple projects, shared VPC, peering, and hybrid connectivity can become complex. Misconfigurations in routes, firewall rules, or IAM permissions can lead to connectivity issues or unintended exposure. Many organizations require strong network engineering practices and automation to manage changes safely.
Cost management can be difficult
Network egress, inter-region traffic, VPN/Interconnect usage, and load balancing can introduce variable costs that are not always obvious during initial design. Multi-region architectures and high-throughput connectivity can increase spend quickly. Teams often need detailed monitoring and chargeback practices to keep network costs predictable.
Vendor-specific networking constructs
Some capabilities (for example, global VPC behavior, firewall policy hierarchy, and service integrations) are implemented in Google Cloud-specific ways. This can increase migration effort for organizations aiming for portability across cloud providers or between hosting environments. Network designs may need refactoring when moving workloads to different platforms.
Plan & Pricing
Pricing model: Pay-as-you-go (usage-based).
Free tier/trial:
- Google Cloud Free Tier / product-level always-free usage applies (some network allowances such as small free egress allowances shown on the VPC pricing page).
- Google Cloud Free Trial ($300 credit for 91 days) is available for new customers.
Example costs (selected, per official VPC pricing page):
- Internet data transfer (Premium Tier) — to North America: 0–1 GiB = $0.00 (free); 1–1,024 GiB = $0.12 / GiB; 1,024–10,240 GiB = $0.11 / GiB; 10,240+ GiB = $0.08 / GiB.
- VM-to-VM inter-zone (same region, different zone) internal IP: $0.01 / GiB.
- Inter-region VM-to-VM (example): North America -> North America = $0.02 / GiB (other region combinations have different rates and tiers).
- External (public) IP addresses: In-use static/ephemeral on standard VMs = $0.005 / hour; static reserved but unused = $0.01 / hour; preemptible/Spot in-use = $0.0025 / hour. (Static IPs assigned to forwarding rules or used for Cloud VPN tunnels: No charge.)
- Private Service Connect: forwarding rule endpoint = $0.01 / hour; consumer data processing charged per GiB (example tiers: $0.01 / GiB up to 1 PB, lower tiered rates above).
- Network telemetry (VPC Flow Logs, Firewall Rules Logging, Cloud NAT logging): 0–10,240 GiB = $0.25 / GiB; lower per-GiB prices at higher volumes.
- Internal Application Load Balancer: proxy instance charge = $0.025 / proxy-instance-hour; minimum allocation = 3 proxy instances (minimum proxy-instance charge example = 3 * $0.025 = $0.075 / hour for a deployed internal managed load balancer). Data processing charged per GiB (example $0.008 / GiB for some load balancer data processing).
- Cloud NAT: connector instances billed as Compute Engine VMs (charged at the VM instance type pricing), and Cloud NAT logging included in network telemetry charges.
Discount options / pricing structure notes:
- Many network charges are tiered by monthly usage (per-GiB volume tiers) — per-page tiered rates apply (discounts at higher GiB tiers).
- For very large volumes (for example, beyond 500 TiB) Google directs customers to contact sales for pricing.
- Customers with negotiated contracts or committed spend can receive custom pricing via sales/enterprise agreements.
Key notes & limitations:
- Inbound data transfer is generally uncharged; responses/outbound are charged.
- Some items (internal IP addresses, certain intra-zone traffic) are free. Several charges vary by region and by Network Service Tier (Premium vs Standard).
