Data Protection in Hybrid Enterprise Data Lake Environment
Download as PPTX, PDF0 likes369 views
This document discusses data protection in hybrid data lake environments using Cloudera's Data Lifecycle Manager (DLM) service. It provides an overview of DLM's capabilities for replicating data between on-premises and cloud environments, including HDFS, Hive, Ranger policies, and metadata. Key features highlighted are incremental replication of Hive metadata and data, HDFS snapshot-based replication between Hadoop clusters, and replication to cloud storage providers like AWS S3, Azure ADLS, and GCP. The document also demonstrates DLM's user interface and replication of data and security policies between on-prem and cloud clusters.
