Description

eBPF host routing in Advanced Container Networking Services for AKS is now available in public preview. 


As containerized applications scale across distributed environments, traditional networking approaches can introduce latency and reduce throughput. To address this, Azure CNI powered by Cilium now offers eBPF Host Routing in public preview for Azure Kubernetes Service. 

This feature uses eBPF technology to embed routing logic directly into the Linux kernel, eliminating the need for iptables and reducing reliance on the host network stack. By enabling Cilium to make direct routing decisions, eBPF host routing delivers lower latency, fewer network hops, and higher throughput for Kubernetes clusters.
