1. A method of cross-domain policy orchestration, comprising:
executing, with a cross-domain automation (CDA) controller, a macro-segmentation of a plurality of domains based at least in part on determining mappings between individual domain controllers associated with the plurality of domains, the mappings comprising metadata enabling communication between the individual domain controllers;
creating, by the CDA controller, a local policy matrix based on policies of individual domains received from the individual domain controllers;
generating a merged policy matrix based on the local policy matrix and the policies received from the individual domain controllers; and
executing, with the CDA controller, a micro-segmentation of particular policies associated with one or more groups across the plurality of domains based at least in part on the merged policy matrix.
