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).
