1. A cloud-based method for maintaining a distributed cloud spectrum access system (SAS), the method comprising:
syncing one or more frontend databases at a frontend-SAS with corresponding backend databases at a backend-SAS;
monitoring a connection between the frontend-SAS and the backend-SAS;
determining the connection between the frontend-SAS and the backend-SAS has been severed;
continuing to operate the frontend-SAS within an interference headroom, wherein operation within the margin of an interference headroom guarantees there is controlled interference to dynamic incumbents on the same frequency by decreasing one or more transmissions that are potentially harmful to dynamic incumbents once the connection is severed;
performing one or more robustness mechanisms to reestablish the connection between the frontend-SAS and the backend-SAS and to minimize impact to the frontend-SAS; and
upon determining the connection is reestablished, reconciling the one or more frontend databases at the frontend-SAS with the corresponding backend databases at the backend-SAS.
