Azure SQL Data Warehouse and Polybase

5. The hype curve

6. Why on-premise Established data warehouse Sensitive data Not ready
A little of everything?

7. Why cloud? Struggling to handle amount of data on-premise
Need more flexibility
No established data warehouse
Lacking own infrastructure
Economoy of scale

8. Azure Stack So.. What about this Azure Stack I keep hearing about?
What’s cool about Azure Stack?
Prepackaged and tuned hardware + software
Definately hybrid – full Azure experience in your data center
BUT:
- Limited set of use cases
- Not a solution for data warehousing

9. SQL Data Warehouse and Polybase
Not your regular OLAP
Scalable, Parallel Processing
Limitations

10. Azure Analysis Services
SSAS Tabular mode in the cloud…
Connects directly to Azure SQL Server
Enterprise Data Gateway to on-premise
Needs Azure AD
Pricing
Bugs

11. What is Polybase? Introduced in SQL Server 2016
Also native to Azure SQL DWH
«Big data» integration
Limitations

12. SQL Server and Polybase
Expansion pack to existing DWH
Cloud storage and compute, on-premise DWH
Limitations
