 This page provides YAML examples for deploying Active-Active Redis Enterprise databases across multiple Kubernetes clusters. Active-Active databases provide multi-master replication with conflict resolution, enabling global distribution and local read/write access.
 
-To learn more, see [Active-Active databases]({{< relref "/operate/kubernetes/active-active" >}}).
+For complete deployment instructions, see [Active-Active databases]({{< relref "/operate/kubernetes/active-active" >}}).
 
-## Architecture
+## Namespace examples
 
-This example shows a two-cluster Active-Active setup:
-- Cluster 1: `rec-chicago` in namespace `ns-chicago`
-- Cluster 2: `rec-boston` in namespace `ns-boston`
+A namespace is an abstraction used by Kubernetes to support multiple virtual clusters on the same physical cluster.

 ## Active-Active database examples
 
-The RedisEnterpriseActiveActiveDatabase (REAADB) resource defines the Active-Active database.
-
-Plain example:
+Active-Active databases are geo-distributed databases that span multiple Redis Enterprise clusters and use multi-primary replication and conflict-free replicated data types (CRDTs).
