  Both observational and theoretical evidence point at outflows originating
from accretion disks as fundamental ingredients of active galactic nuclei
(AGN). These outflows can have more than one component, for example an unbound
supersonic wind and a failed wind (FW). The latter is a prediction of the
simulations of radiation-driven disk outflows which show that the former is
accompanied by an inner failed component, where the flow struggles to escape
from the strong gravitational pull of the supermassive black hole. This FW
component could provide a physical framework to interpret various
phenomenological components of AGN. Here we briefly discuss a few of them: the
broad line region, the X-ray obscurer, and the X-ray corona.
