1. A hybrid cloud cellular network, comprising:
a radio access network (RAN) comprising a plurality of base stations (BSs);
a plurality of national data center (NDC) instantiations on a cloud computing platform, wherein:
the cloud computing platform is communicatively connected with the RAN; and
a first set of NDC instantiations of the plurality of NDC instantiations is executed in a first data center group region of the cloud computing platform and a second set of NDC instantiations of the plurality of NDC instantiations is executed in a second data center group region of the cloud computing platform;
a plurality of network functions (NFs), wherein an instance of each NF is executed within each NDC instantiation of the plurality of NDC instantiations;
a cellular network database function, wherein:
an instance of the cellular network database function is executed within each NDC instantiation of the plurality of NDC instantiations; and
each instance of the cellular network database function updates each other instance of the cellular network database function across the plurality of NDC instantiations; and
a plurality of regional data center (RDC) instantiations, wherein at least one RDC instantiation of the plurality of RDC instantiations is implemented at a same data center group at which an NDC instantiation of the plurality of NDC instantiations is implemented.
