{{< warning >}}
Kubernetes limitation: OSS Cluster API can only be used by clients running within the same Kubernetes cluster as the Redis Enterprise pods. External clients cannot use OSS Cluster API due to pod IP address accessibility limitations.
{{< /warning >}}

You can use the OSS Cluster API along with other Redis Software high availability
to get high performance with low latency
and let applications stay current with cluster topology changes, including add node, remove node, and node failover.

For more about working with the OSS Cluster API in Redis Software, see [Enable OSS Cluster API]({{< relref "/operate/rs/databases/configure/oss-cluster-api" >}}). 

To learn how to enable OSS Cluster API in Redis Cloud, see [Clustering Redis databases]({{< relref "/operate/rc/databases/configuration/clustering#cluster-api" >}}).
