Cilium eBPF Hybrid Service Mesh & Private Cloud Topology

High-performance container networking using Cilium eBPF without kube-proxy, eliminating iptables overhead and routing traffic locally to avoid AZ transit tolls.

Mathematical Breakeven Inflection Curve

Reduces network spend by 40% - 70% in high-volume microservice topologies (> 50 TB/mo internal east-west traffic).

3 Maturity Tiers & Infrastructure Specifications
