About This Architecture

Multi-tier microservices architecture on GCP GKE with customer and agent services running in separate deployments across two nodes. Cloud Load Balancing routes external traffic through a Kubernetes Ingress to customer-svc and agent-svc, each backed by replicated pods for high availability. Both services connect to a managed Cloud SQL PostgreSQL instance in a private subnet, isolating database traffic within the VPC. This pattern demonstrates GKE best practices: namespace isolation, service discovery, horizontal pod autoscaling readiness, and secure database connectivity.

How do I deploy multiple microservices on GCP GKE with load balancing and a managed database?

This diagram shows a production GKE setup where Cloud Load Balancing routes traffic through a Kubernetes Ingress to customer-svc and agent-svc deployments, each running replicated pods across nodes. All services securely connect to a Cloud SQL PostgreSQL instance in a private subnet, ensuring database isolation and compliance with VPC security best practices.
