Cloud data lake or data lake A CDP cluster on the cloud, using virtual machines, with data retained on cloud storage. A cloud data lake requires minimal services for metadata and governance, such as Hive metastore, Ranger, and Atlas.

On-premises cluster A CDH cluster in a data center or a CDP Private Cloud Base cluster, with Apache services running, such as HDFS, Yarn, HMS, Hiveserver2, Ranger, and Atlas. Replication behavior is similar to IaaS cluster replication. The data is on local HDFS.
Replication policy A set of rules applied to a replication relationship. The rules include which clusters serve as source and destination, the type of data to replicate, the schedule for replicating data, and so on.
Job An instance of a replication policy that is running or is completed
Source cluster The cluster that contains the source data that is replicated to a destination cluster. Source data could be an HDFS dataset, Hive database, or HBase tables.
Target cluster The cluster to which the data is replicated.
