The Way to Cloud Foundry with IPv4+IPv6 Dual Stack at SAP

on YouTube ↗21m

" summary

SAP runs Cloud Foundry for thousands of users and hundreds of thousands of apps and is enabling IPv6 by first testing dual-stack ingress on AWS while keeping IPv4 for compatibility. Current estate uses 27 NAT gateways to avoid port exhaustion; experiments compare terminating IPv6 at load balancers, a SOCKS5 proxy for minimal egress, 464xlat translation, and a roadmap toward per-container IPv6 addresses to eliminate port remapping, reduce NAT, and simplify egress identity across hyperscalers.
