IstioD - from microservices to monolithic
summary
Istio consolidates multiple control-plane services into an istiod single binary, moving Mixer logic into Envoy, merging citadel injector node agent and pilot responsibilities, and adding canary upgrades and external control-plane options. The result is fewer objects and simpler ops: CRDs down from 23 to 12, control-plane components from seven to one, daemonsets for node agents to zero, faster startup and improved performance, demonstrated with kubernetes, Envoy sidecars, istioctl analyze and a Bookinfo demo.
