-A remote read replica topic is a read-only topic that mirrors a topic on a different cluster. You can create a separate remote cluster just for consumers of this topic and populate its topics from object storage. A read-only topic on a remote cluster can serve any consumer, without increasing the load on the source cluster. Because these read-only topics access data directly from object storage, there's no impact to the performance of the cluster.

You can create a separate remote cluster just for consumers of this topic and populate its topics from object storage. A read-only topic on a remote cluster can serve any consumer, without increasing the load on the source cluster. Because these read-only topics access data directly from object storage, there's no impact to the performance of the cluster. Remote read replica topics do not store any data. When a cluster running a remote read replica is terminated, the topic data only exists on the origin cluster.
 
-Redpanda Cloud supports remote read replicas with ephemeral BYOC clusters. Ephemeral clusters are temporary clusters created to handle specific, transient workloads or tasks. After processing, the cluster is terminated to free up resources and reduce costs.
+Redpanda Cloud supports remote read replica topics in BYOC clusters on AWS or GCP. These clusters can be ephemeral; that is, created temporarily to handle specific or transient workloads, but they don't have to be. The ability to make them ephemeral provides flexibility and cost efficiency: you can scale resources up or down as needed and pay only for what you use.

+xref:get-started:cluster-types/byoc/remote-read-replicas.adoc[Remote read replicas] are now generally available (GA) for BYOC clusters on AWS and GCP. This feature allows you to create read-only topics that mirror a topic on a different cluster, providing greater flexibility and scalability for your data streaming needs.
