About This Architecture

Multi-zone GKE microservices architecture with Cloud Armor WAF, Cloud Load Balancing, and Cloud CDN protecting frontend and backend services across us-central1-a and us-central1-b zones. Frontend and API deployments with horizontal pod autoscaling route traffic through ingress controllers, while backend services connect to Cloud SQL primary-replica pairs, Memorystore Redis, Cloud Firestore, and Cloud Pub/Sub for messaging. Cloud IAM, Cloud Monitoring, and Cloud Logging provide security, observability, and audit trails across the GCP Project web-app-prod VPC. Fork this diagram to customize subnets, add additional zones, or integrate Cloud Run or Compute Engine workloads alongside your GKE clusters. This architecture demonstrates GCP best practices for production workloads: defense-in-depth with Cloud Armor, multi-zone redundancy, managed database replication, and comprehensive observability.

How do I design a highly available multi-zone microservices architecture on GCP GKE with database replication and DDoS protection?

This diagram shows a production GCP architecture spanning two zones (us-central1-a and us-central1-b) with GKE clusters running frontend and backend microservices protected by Cloud Armor WAF and Cloud Load Balancing. Cloud SQL primary-replica replication, Memorystore Redis caching, Cloud Firestore, and Cloud Pub/Sub provide data persistence and event-driven communication, while Cloud IAM, Cloud M
