Various methods, apparatuses/systems, and media for automatically deploying an SDN are disclosed. A processor implements a declarative model for an SDN deployment and receives, in the declarative model, service order data from a user corresponding to the SDN deployment. The service order data includes high-level declarative statement data specifying a desired end-state of the SDN deployment. The processor translates the high-level declarative statement data into a low-level specification data that includes data corresponding to a topology and how the SDN should be deployed; creates a run-time topology model based on the low-level specification data; determines whether the service order is valid or not by comparing the low-level specification data against predefined policies and infrastructure constraints data corresponding to execution of the SDN deployment; and automatically executes deployment of the SDN based on a determination that the service order is valid in response to the run-time topology model.
