Systems, methods, and apparatus for an adaptive self-optimizing network using closed-loop feedback are disclosed. A method for sharing network resources comprises receiving, by a network operations center (NOC), access requests for users subscribed to an external network. The method further comprises receiving, by the NOC, a summary of key performance indicators from at least one internal network. Also, the method comprises determining, by the NOC, whether at least one internal network has available resources by analyzing the summary of key performance indicators and user demand from the access requests. Further, the method comprises allowing, by the NOC when the NOC determines that there are available resources, at least some of the users from the external network to connect to at least one internal network according to the available resources.
