We write:
Active-Active geo-distributed replication
Active-Active Redis Enterprise databases distribute your replicated data across multiple nodes and availability zones. This increases the durability of your database by reducing the likelihood of data or availability loss. It also reduces data access latency.
I think it is confusing to mention availability zones, rather than geographic regions. It overlaps with the idea of Multi AZ / Rackzone awareness?
