Where Can I Run FLaNK Easily?
CDP services are optimized for the elastic compute &
‘always-on’ storage services provided by any cloud provider
Web service hosted and managed by Cloudera
Hosted in the your cloud environment, but managed by the
CDP Management Console
Shared Data Experience (SDX) technologies form a secure and
governed data lake backed by object storage (S3, ADLS, GCS)
Flow Management Streams Messaging Streaming Analytics
