How to build multi-disciplinary analytics
applications on a shared data platform

Challenges in data management
Many data silos, each requiring its own proprietary tools and infrastructure
Different vendors, products, and services on-premises versus in cloud
A fragmented approach is difficult, expensive, and risky

Negative consequences for your business
Increased operational costs
many distinct environments
to buy and build
Increased staff overhead
many distinct tools to learn
and support
Increased security risks
many distinct frameworks to enforce
Decreased business insights
narrow data sets and analytics
rigidity
Decreased business agility –
outdated and limiting for
applications
Decreased governance capability –
no common visibility across stores

Shared Storage (HDFS, Kudu)
Traditional on-premises deployments perform reasonably
well
Strong multi-function support
Strong shared data experience
Strong information security model
Moderate cost management
Moderate tenant isolation
Moderate workload elasticity
Weak on self service
Weak on speed of deployment
Shared Data Experience (Metadata, Security, Governance)
One physical cluster provides a shared data experience
to multiple workloads and tenants
… but not good enough going forward

Traditional cloud deployments are strong where on-premises
is weak, but at the expense of creating workload silos
Moderate multi-function support
Weak on shared data experience
Weak information security model

Strong on tenant isolation
Strong on workload elasticity
Strong on self service
Strong on speed of deployment

What is a workload?
Data + Data Context + Compute
Data Context:
• HMS: Schema definitions
• Sentry: Security
authorizations
• Navigator: Audit logs
• Navigator: Business glossary
• Navigator: Business metadata
• Navigator: Lineage

13. 13© Cloudera, Inc. All rights reserved.
What about multiple workloads?

Hive/HMS
Sentry

Data context with multiple workloads
Traditional Hadoop clusters
contain compute, data, and
data context
Transient Hadoop clusters
contain compute and data context,
but externalize data
HDFS, Kudu, S3, Private Cloud
Storage
Why is data
context stored
in each cluster,
and not
alongside
the data?
?

15. 15© Cloudera, Inc. All rights reserved.
The data context consistency problem
Compute and data are becoming further separated
• Compute is stateless: cloud-based or on-prem, either transient or long-running
• Data is stateful: cloud-based or on-prem in HDFS, Kudu, S3, ADLS, Isilon, etc.
What about data context?
• Schema Definitions (Hive Metastore)
• Permissions (Apache Sentry)
• Encryption Keys (KMS)
• Governance (Cloudera Navigator)
Data context should be stateful, but currently is stateless
• This creates synchronization and usability challenges for admins and end users
alike

Solution: Shared Data Experience

Benefits:
• Common schemas, access permissions, classifications,
and governance across all workloads
• Reduced cost of ownership: less hardware and software
to manage
• Increased end-user productivity: data is presented
consistently in every cluster
• Faster expansion: admins don’t have to recreate data
context services with each new cluster

Two deployment options
Cloudera SDX
Cloudera SDX: Customer-managed
• RDS-backed Hive Metastore
• RDS-backed Apache Sentry
• Customer-managed Cloudera Navigator
Ideal for:
• Director-launched workloads
• CM-managed workloads
Cloudera Altus SDX: Cloudera-
managed
• Serverless Hive Metastore
• Serverless Apache Sentry
• Serverless Cloudera Navigator
Ideal for:
• Altus SDX workloads
• Hybrid workloads

Cloud deployments with SDX optimize for all design goals
Shared Data Experience (Metadata, Security, Governance)
One logical cluster provides a shared data experience to multiple
workloads and tenants
SDX makes it possible to transfer on-premises design wins to cloud

Using Predictive Maintenance to Improve
Performance and Reduce Fleet Downtime
• OnCommand Connection is collecting
telematics and geolocation data across
the fleet
• Reduced maintenance costs to $.03 per
mile from $.12-$.15 per mile
• Centralizing data from 13 systems with
varying frequency and semantic
definitions
• Real-time visibility of 300,000+ trucks in
order to improve uptime and vehicle
performance
