GCP GKE Secure Orchestration Architecture implements identity-aware access using Cloud IAP and OAuth 2.1 to gate external user traffic through a Global Load Balancer into a VPC-native GKE cluster. External users authenticate via Google Sign-In, with Cloud IAP enforcing zero-trust access before requests reach the Orchestrator Pod, which coordinates Kubernetes Worker Jobs. Worker Jobs interact with managed services including Memorystore Redis for caching and Cloud Storage Buckets for persistent data, all within a unified GCP Project security boundary. This architecture demonstrates defense-in-depth by combining network isolation, identity verification, and least-privilege service access patterns.
