Rete & Interconnect

Google's private backbone and dedicated connectivity: the traffic travels on YouTube's network, not on the internet.

01 · What it is

Rete globale & Interconnect, made clear.

The network is Google Cloud's real superpower: the VPC is GLOBAL (a single network across all regions, no peering between regions), traffic between Google sites travels on the private backbone, the load balancer is a worldwide anycast with a single IP. Interconnect brings your data center into this network, up to 100 Gbps.

Globale
one VPC across all regions: the multi-region architecture gets simpler
Anycast
a single global IP for the load balancer: the world served nearby
100G
Dedicated Interconnect: the direct wire to your data center

02 · How to use it well

The things that make the difference.

The topology

Users and sites worldwidewherever they are
Global LB
Global VPC
Private backbone
entry · single network · Google transport
Interconnect / VPNthe bridge to on-prem
Cloud Armor & NGFWthe defense at the edge
A single, planetary network

Shared VPC design

Shared VPC and subnets per environment: the corporate network in the cloud, tidy from day one.

Redundant Interconnect

Two circuits, two edges: the 99.99% SLA is built with the right topology.

Private Service Connect

Managed services reached privately: no internet in the middle.

Governed egress

Google's network is paid on the way out: tiers and architecture decide the bill.

03 · In depth

Google's network as the perimeter

Google's VPC is global by nature: one network, subnets per region, internal routing without VPNs between regions; Shared VPC centralizes in a host project, Private Service Connect exposes services without crossing the internet, Cloud Interconnect reaches 100G (partner options too). On top: an anycast global load balancer with a single worldwide IP, Cloud Armor for WAF/DDoS and the Network Connectivity Center as the hub.

  • Global VPC — regions connected by design: no VPN mesh to maintain
  • Shared VPC — the network centrally governed, the projects consume it
  • Private Service Connect — services (SaaS too) on private IPs: internet out of the flows
  • Global LB — one anycast IP for the world: failover between regions is routing
  • Cloud Armor — WAF, rate limiting and Google-scale DDoS protection
  • Interconnect — dedicated 10/100G, also via local partners
04 · Numbers and lifecycle

The numbers that matter.

1
one VPC for the world: the topology gets simpler
100G
the maximum Interconnect per circuit
anycast
one global IP: latency decides the region
0
internal VPNs between regions: the backbone is Google's
The network is where the cloud is won or lost: Shared VPC, PSC and Interconnect designed by us — the landing zone that lasts years.
05 · Use cases

Where it really pays off.

Simple multi-region

Apps across continents without a cobweb of VPNs.

Serious hybrid

SAP on site, analytics in the cloud: the wire that holds.

Global performance

Distant users, short latencies: the backbone works for you.

In Google Cloud the network isn't plumbing, it's a competitive advantage: we design it to exploit it.
