## AI overview

The concluding article in an Istio control-plane series presents a mechanism-based decision tree for choosing among Istio CRDs, Gateway API/GAMMA, and eBPF L4 networking. It explains that Istio CRDs and Gateway API are alternative configuration inputs compiled by istiod into xDS resources, while eBPF L4 avoids xDS entirely. It also identifies open questions around configuration-activation SLOs, Ambient maturity, and coexistence between configuration models.
