About This Architecture

GCP Shared VPC production architecture centralizes network governance across host and service projects, routing internet traffic through Cloud CDN, Cloud Armor WAF, and Global HTTP(S) Load Balancer to a GKE Autopilot cluster in us-central1. The cluster runs containerized Next.js frontends, FastAPI backends, and Celery workers across dedicated namespaces, with egress controlled by Cloud NAT and Cloud Router. Data persistence spans Cloud SQL PostgreSQL 15 with read replicas in us-east1 for disaster recovery, Memorystore Redis 7.0 for session caching, and event-driven pipelines via Pub/Sub feeding Cloud Run order processors and Dataflow jobs into BigQuery analytics. This architecture demonstrates enterprise-grade multi-tenancy, high availability, and observability through Cloud Monitoring, Logging, and Trace.
