Multi-Cloud Global Content Distribution at Cloud Native Speeds
summary
K8GB claims to replace proprietary GSLB with an open source, cloud‑native GeoDNS controller that runs next to workloads (it has no master cluster), uses an embedded CoreDNS plus external-dns for automated NS/A glue delegation, and supports failover, weighted round‑robin and GeoIP via a MaxMind GeoLite2 MMDB and EDNS client subnet. It is production‑proven since 2019 at multiple banks (three public adopters), demoed working for failover within a 60s TTL and GeoIP routing (works with resolvers that preserve EDNS, Google but not Cloudflare).
