Cloud Native Multi Cluster/Multicloud Global Load Balancer for Kubernetes
summary
K8GB is an open-source CNCF Sandbox global load balancer for Kubernetes that routes traffic across geographically dispersed clusters without a separate control plane, no dedicated control plane. It installs a GSLB CRD, a CoreDNS instance with a plugin and uses ExternalDNS to delegate zones so upstream providers (Route53, on‑prem BIND) forward queries. Health is determined by Ingress status, DNS updates use RFC2136 zone transfers and TTL tuning (demo uses 10s) to achieve fast failover; strategies include round‑robin, geo‑tagged and weighted failover, demo on k3s + NGINX shows successful cross‑cluster failover.
