This illustration shows zone distribution in a KVStore, without Master Affinity in use. The diagram has three rectangular boxes, from left to right, representing Primary Zones 1, 2, and 3. To the right of the Primary Zones are two secondary zones, Zones 4 and 5. Two shards, Shard 1 and 2, overlay all zones. Shard 1 has one master node in Primary Zone 2, and Shard 2 has a master node in Primary Zone 1.
