Global Container Networks on Kubernetes at DigitalOcean - Andrew Sy Kim, DigitalOcean

on YouTube ↗37m

" summary

DigitalOcean replaces overlay pod networking with BGP-backed routing so clusters advertise pod and service IPs via BGP into the data‑center backbone using kube‑router as a daemonset, turning service IPs into anycast service IPs routable across the backbone. Result: lower packet overhead, preserved source IPs, no mandatory ingress daemonsets, easier node ops, and global static IPs for multi‑region deployments. Tradeoffs: proxy‑mesh bandwidth, unique IPv4 planning, and BGP convergence visibility; production at hundreds of nodes proves the model works.
