Claim 8:
9. A method for establishing geographic redundancy and high availability for a hybrid cellular network, the method comprising:
establishing a plurality of national data centers (NDCs) on a public cloud computing platform, wherein:
the public cloud computing platform is communicatively connected with a radio access network (RAN) of the hybrid cellular network at a plurality of locations;
the RAN comprises a plurality of base stations (BSs), each BS of the plurality of BSs comprising: one or more antennas, one or more radio units (RUs), and a distributed unit (DU);
establishing the plurality of NDCs on the public cloud computing platform comprises:
establishing a first set of NDCs of the plurality of NDCs as part of a first data center group region; and
establishing a second set of NDCs of the plurality of NDCs as part of a second data center group region;

executing, within each NDC of the plurality of NDCs, a plurality of network functions (NFs);
executing, within each NDC of the plurality of NDCs, an instance of a cellular network database function on the public cloud computing platform, wherein each instance of the cellular network database function updates each other instance of the cellular network database function across the plurality of NDCs;
processing cellular network core traffic for the RAN using the plurality of NDCs including the plurality of NFs and the cellular network database function; and
establishing a plurality of regional data centers (RDCs) on the public cloud computing platform, which comprises establishing at least one RDC of the plurality of RDCs at a same data center group at which an NDC of the plurality of NDCs is implemented and establishing at least one RDC of the plurality of RDCs at a different data center group at which no NDC of the plurality of NDCs is established.
