-Database replication helps ensure high availability. When replication is enabled, your dataset is duplicated to create a replica, which stays in sync with the primary dataset. Replication allows for automatic failover and greater fault tolerance. This can prevent data loss in the event of a hardware, zone, or regional failure. 
+Database replication helps ensure high availability. 
+
+When replication is enabled, database data is stored in two locations: a _primary_ (also known as a _master_) and a _replica_ are automatically synchronized as data changes.  
+
+Should anything happen to the primary copy, such as a network communication spike or hardware failure, the replica becomes the new primary and customer connectivity continues as normal.  This automatic failover provides greater fault tolerance; it helps prevent data loss in the event of hardware, communication, or other network failures. 
 
 Redis Enterprise Cloud supports three levels of replication:
 
 - _No replication_ means that you will have a single copy of your database.
+
 - _Single-zone replication_ means that your database will have a primary and a replica located in the same cloud region. If anything happens to the primary, the replica takes over and becomes the new primary.
+
 - _Multi-zone replication_ means that the primary and its replicas are stored in different regions. This means that your database can remain online even if an entire region becomes unavailable.
 
-Your replication options depend on which subscription plan you're using:
+Your replication options depend on your subscription plan:
 
 - _Free_ plans do not support replication.
-- _Fixed_ plans allow you to choose between no replication or single-zone replication.
-- _Flexible_ plans enable single-zone replication by default and allow you to upgrade to multi-zone replication. 
+- _Fixed_ plans let you choose between single-zone replication and no replication.  
+- _Flexible_ plans enable single-zone replication by default and permit upgrading to multi-zone replication. (Support varies between cloud providers and their regions.)
