Realm, Zonegroup and Zone

For Multi-site purposes used. each part is for isolating and grouping types of resources and scenarios. At each level, we can have synchronization and replication.

Multi-Zone: To create multiple Zone, We have 2 options. First, our secondary zone can synchronize all the data with the Primary zone. The secondary zone can receive API but it redirects it to the Primary zone and then operations work on itself. Second, We can have multiple zones that are not replicated and work separately.

Multi-ZoneGroup: With Multiple ZoneGroups, we can have better management, Failover and Disaster Recovery and other options.
