Who am I?
Sr. Content Developer working on Business Intelligence products

3. Starting with Power BI Desktop

4. Getting data into PBI Desktop
Data pulled into PBI Desktop
Three options:
Import
DirectQuery
Live connections (SSAS only)
Data is streamed from source
SQL Server Analysis Services
Live Power BI reports & dashboards
Live query
Cloud
On-premises
Data Source
Direct query
Scheduled refresh

5. Supported import sources
More added regularly!
Supported cloud sources:
SaaS sources
Azure – SQL, DW, Blob, Table, HDInsight, Marketplace
SharePoint, web sources, Odata
OneDrive
Supported on-prem sources:
SQL Server, Teradata, Oracle, DB2, MySQL, PostgreSQL, SAP BW, SAP HANA
Sybase, Access, Custom SQL, Custom ODBC Drivers
SQL Server Analysis Services
Files/folder, SharePoint on-premises

6. What this looks like…

7. File location and freshness

8. Files from your computer
File locations
Files from your computer
Files in the cloud

9. What location means… Local Files: Only copy the model to the cloud
Local files is never updated or pulled from
About hourly
Files in the cloud:
Model is copied to Azure BI backend
Poll original file for updates
Refresh will update model and original file

10. Refresh & Gateways

11. How do you want to refresh data?
Import (cached mode)
DirectQuery or Live connection
Refresh frequency
Scheduled - hourly or daily
Real-time
Performance
No noticeable delay since data is already cached
Depends on how fast the data source is as queries are executed in real-time
Data storage in Power BI
Since it is cached mode, data is stored in the cloud
No data is stored in Power BI. Data is always on-premises*
Data size
Current limit of 1GB (compressed) per model
The on-premises database is the limit; no Power BI limitation
Row level security
No support for on-prem row level security. Supports Cloud RLS.
Re-use on-prem role based row level security for Analysis Services. Non-SSAS supports Cloud RLS.
*Some data is cached for optimizing first-time load performance

12. Power BI Gateway - Personal
Self-service refresh – no IT dependency
Easy & simple to use: Lightweight one- click installer running on your computer
One Personal Gateway per user
Runs either as a service or an app

13. On-premises Data Gateway
Centralized way to refresh on-premises content in Power BI
Access control to data sources
Monitor and track usage
Live, interactive query with on-premises data sources

14. Personal v/s On-premises data gateway
Personal Gateway
On-premises data gateway (Enterprise gateway)
Target Persona
Business analyst sets up and uses the gateway for her data sources
BI Admins set up the gateway for their department/ company
Multiple users use the gateway setup by the admins
Usage
Directly by analysts
BI Admin
Features
Import with scheduled refresh
Direct query and scheduled refresh
Data source connections managed per user
Central data source mgmt. and access control
No central monitoring/control
Central monitoring and control
Services supported
Power BI
Power BI, PowerApps, Microsoft Flow, and Azure Logic Apps

15. Data gateway and Analysis Services
Gateway Service Account needs to be Admin on AS Instance
Org Account sent via Effective User Name connection property
address
address has to match UPN for account in local domain
May need to use Azure AD DirSync or can use alternate UPN Suffix

16. How this works… Power BI Gateway service Install & configure gateway
Scheduler
Service
How this works…
creds
Install & configure gateway
Create a data source or schedule refresh
Interact with report, schedule refresh or refresh now
Gateway Service pushes to Service Bus
Gateway polls bus looking for requests
Gateway takes request and decrypts creds
Gateway connects and runs query
Gateway sends results back up stack
Gateway service
Cloud
On-premises DB
