1. A system comprising:
a plurality of computing devices at a first geographic location able to communicate over a network with a plurality of computing devices at a second geographic location that is remote from the first geographic location, at least one computing device of the plurality of computing devices at the first geographic location configured to perform operations comprising:
dividing metadata into a plurality of partitions, the metadata corresponding to object data stored at a storage location, wherein a leader computing device and at least one follower computing device of the plurality of computing devices at the first geographic location maintain a copy of the metadata included in a first partition of the plurality of partitions, the leader computing device and the at least one follower computing device exchanging periodic heartbeat communications related to the first partition at least for monitoring availability of each other;
receiving a data structure from one of the plurality of computing devices at the second geographic location, the data structure indicating a frequency of access load on one or more of the computing devices of the plurality of computing devices at the second geographic location;
based at least in part on receiving the data structure, determining that at least one computing device at the second geographic location has a lower frequency of access load than at least one of the leader computing device or the at least one follower computing device at the first geographic location; and
based at least on determining from the data structure that the at least one computing device at the second geographic location has the lower frequency of access load, migrating the metadata of the first partition to at least one of the plurality of computing devices at the second geographic location,
wherein, following the migrating the metadata, a leader computing device and at least one follower computing device at the second geographic location each maintain a copy of the metadata of the first partition and exchange periodic heartbeat communications related to the first partition at least for monitoring availability of each other.
