Building a High-Availability Ingress Solution with Envoy Proxy on Kubernetes

Moving from External Load Balancer to Cloud-Native Architecture

The Challenge

In on-premise Kubernetes deployments, achieving high availability for ingress traffic often relies on external load balancers running on dedicated VMs. While functional, this approach creates single points of failure, adds operational complexity, and wastes valuable infrastructure resources.

In this guide, I’ll walk you through migrating from an external Envoy load balancer to a fully integrated, Kubernetes-native solution using DaemonSet deployments, Keepalived for VIP management, and host networking for optimal performance.

The root cause? Their legacy DNS server couldn’t handle the traffic spike, taking 47 minutes to resolve the issue.

Meanwhile, their competitor running CoreDNS experienced the same traffic surge but stayed online, gaining 2.3 million new subscribers that day.

This isn’t just another “infrastructure matters” story. This is about the invisible foundation of the internet that separates digital empires from digital disasters.
