3. What?
This talk is about ingesting real-time data from many sources and build a dashboard on top it to track in
real time what our stocks are.
This use case is a good example to show the combination of some of the best Apache solutions for
streaming applications.

7. Where?
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
