About This Architecture

Multi-AZ AWS EKS cluster running mTLS-encrypted gRPC services with NLB pass-through TLS termination and automatic scaling across availability zones. Route 53 distributes traffic to Network Load Balancers in each AZ, which pass encrypted TLS connections to Kubernetes Ingress controllers managing ClusterIP services and gRPC pod deployments. Horizontal Pod Autoscaler scales gRPC backend replicas based on demand, while Cluster Autoscaler provisions EC2 worker nodes, with mTLS certificates managed via ACM and Secrets Manager for zero-trust pod-to-pod communication. This architecture demonstrates production-grade security, high availability, and cost-efficient auto-scaling for latency-sensitive gRPC workloads.

How do I design a production AWS EKS cluster with mTLS gRPC services across multiple availability zones?

This diagram shows a multi-AZ EKS architecture where Route 53 routes mTLS clients to NLBs in each AZ, which pass encrypted TLS to Kubernetes Ingress controllers and ClusterIP services managing gRPC pod deployments. HPA scales pods by demand, Cluster Autoscaler provisions EC2 worker nodes, and ACM plus Secrets Manager manage mTLS certificates for zero-trust pod-to-pod communication across AZ-1 and
