Demand Problem
IT is an obstacle rather than a partner
- Business Leader – “Moving from concept to innovation is slow and expensive”
- Analyst – Either throwing data away, not using it at all, or waiting to get access
Supply Problem
IT struggles to consume, secure, and expose the data produced by the enterprise
Current solutions are rigid and lack the ability to surge capacity
Storage does not scale elastically
Specific examples:
- Repeatedly running out of storage both for archived raw data and on our analytics platforms (virtual machines)
- Months to get an indicator exposed in the EDW.

Benefits
QUANTITATIVE
“10-20x cheaper storage than traditional on-premises data solutions”
– Bill Schmarzo,
CTO Dell EMC Services
Regular data lake storage:
$40/TB/month decreasing to $6/TB/month for cold storage (AWS)
Storage: $0.04-$0.006/GB/Mon
Bandwidth: only out of region
Compute: $0.03/Node/Minute
Catalog: $1/month/user
Power BI: $10/month/user
QUALITATIVE
Data is transformed and cleansed only when needed
- Lower cost
- Maintain data fidelity
Goal: Provide more analytical power and flexibility than a traditional data warehouse at lower cost than traditional on premises raw storage
Facilitates traditional data warehousing through persistent staging
Opens the door to industry leading analytical tools – Hadoop, Spark, Redshift, machine learning while avoiding the complexities of running a cluster
Data Warehouse vs Data Lake
structured, processed
DATA
structured / semi-structured / unstructured, raw schema-on-read
schema-on-write
PROCESSING
schema-on-read
expensive for large data volumes
STORAGE
designed for low-cost storage
less agile, fixed configuration
