SUMMIT China 2023 ## Unleashing the Magic: Harnessing eBPF for Traffic Redirection in Istio Ambient Mode Chun Li & Iris Ding, Intel ## Outline • What is ambient mesh • How ambient mesh works • How reinforces ambient mesh • Next(lesson learned)... ## Background • Ambient mesh is a new Istio data plane mode • Launched in Sep. 2022. announcement • Currently in alpha status, moving forward to beta phase 1. Follow the instructions in Getting Started with Ambient Mesh 2. In istio install stage set the mode to ebpf by ' --set values.cni.ambient.redirectMode="ebpf", e.g.: istioctl install --set
