storing a map of a geographic area using an immutable tree, wherein the immutable tree comprises a plurality of nodes stored using a distributed hash table, the plurality of nodes including a plurality of map tiles, at least two map tiles of the plurality of map tiles covering different geographic subregions of the geographic area of the map;
hosting one or more binary large objects (BLOBs) that correspond to the plurality of map tiles in an origin data plane; and
making the one or more BLOBs available for distribution to one or more client devices using a content delivery network (CDN).
