The so-called Sidecarless of Istio Ambient is, strictly speaking, a change from a sidecar container of pod to a sidecar pod of pods on a worker node. Note that I’m introducing the term sidecar pod here. To implement pods on the same worker node share a sidecar pod, you need to solve the problem of redirecting traffic from all pods to the sidecar pod.

The solution to this problem has gone through two versions during the development of Istio Ambient.
