1. A hybrid cloud cellular network system, comprising:
a cellular radio access network (RAN) comprising a plurality of base stations (BSs), each base station of the plurality of BSs comprising: one or more antennas, one or more radio units (RUs), and a distributed unit (DU);
a plurality of national data centers (NDCs), wherein:
the plurality of NDCs is executed on a public cloud computing platform;
the public cloud computing platform is communicatively connected with the RAN at a plurality of locations;
a first set of NDCs of the plurality of NDCs is part of a first data center group region; and
a second set of NDCs of the plurality of NDCs is part of a second data center group region;
a plurality of network functions (NFs), wherein an instance of each NF is executed within each NDC of the plurality of NDCs on the public cloud computing platform;
a cellular network database function, wherein:
an instance of the cellular network database function is executed within each NDC of the plurality of NDCs on the public cloud computing platform; and
each instance of the cellular network database function updates each other instance of the cellular network database function across the plurality of NDCs; and
a plurality of regional data centers (RDCs), wherein:
at least one RDC of the plurality of RDCs is implemented at a same data center group at which an NDC of the plurality of NDCs is implemented and
at least one RDC of the plurality of RDCs is implemented at different data center group at which no NDC of the plurality of NDCs is executed.
