About This Architecture

Multi-region GCP architecture using Network Connectivity Center (NCC) hub-and-spoke topology with Dedicated Interconnect bridging on-premises infrastructure to four regional spokes. Traffic flows from an on-premises data center through a Core Router and Firewall via Dedicated Interconnect to the NCC Hub, which distributes connectivity to regional spokes in us-central1, us-east1, europe-west1, and asia-southeast1. Each region runs specialized workloads—Compute Engine, GKE, Cloud Run, Cloud Functions—with Cloud SQL primary in us-central1 and read replicas across regions for low-latency access and disaster recovery. This architecture demonstrates hybrid cloud best practices: centralized connectivity management, geographic redundancy, optimized data locality, and seamless on-premises integration. Fork this diagram on Diagrams.so to customize subnets, add additional regions, or adjust interconnect configurations for your organization. The NCC hub pattern eliminates complex mesh networking and simplifies multi-region management compared to traditional VPC peering approaches.

People also ask

How do I design a multi-region GCP network with on-premises connectivity using Network Connectivity Center?

Use NCC's hub-and-spoke topology to centralize connectivity: connect your on-premises data center via Dedicated Interconnect to the NCC Hub in us-central1, then distribute traffic to regional spokes in us-east1, europe-west1, and asia-southeast1. Deploy Cloud SQL primary in the hub region with read replicas in spokes for low-latency queries and automatic failover.
