4 Power BI for the Enterprise Accessing on-premises data from the Power BI Service Refreshable data connections: Relational data Other sources Live data connections: SSAS data model Relational data 4

5 Data Governance and Self-service BI A single version of the truth : Requirement for centrallymanaged data are different across organizations. For some, governance is enforced through a data warehouse & master data management solution. How can we avoid a train wreck? Self-service BI projects may be: Freedom from unnecessary IT process. Proof of concept projects that are strategically migrated to a maintained solution. Out-of-control side projects that work-around proper governance controls. As a client-only tool, connected to centrally-managed & trusted organization data, a self-service reporting solution can provide the best of both worlds when users are trained & efforts are appropriately managed. 7

7 Scope and Scale

8 Data Connection Options Scheduled Refresh <supported sources> <unsupported sources> 8 events/day, 30 minute blocks Uses Gateway for on-prem OneDrive for file sources Direct Connect Analysis Services Tabular and multidimensional Honors role-based security Uses Gateway Currently SSAS is on-prem only DirectQuery <supported sources> SQL Server Uses Gateway Live Streaming Azure Stream Analytics Live Tiles REST API

9 Deployed Desktop Model published model, reports & dashboard multiple organization users

10 Scheduled Refresh Uses gateway to sync published model with onpremises data Cloud or URL accessible data sources File sources in OneDrive or SharePoint Online Up to 8 events per day at 30 minute intervals Free subscription allows one refresh event per day from a non-gateway data source Gateway refresh requires Pro subscription

11 Enterprise Data Sources scheduled refresh SSAS live queries DirectQuery

12 You Gotta Know When to Fold Em Query Folding and source engine optimizations Translates Power Query/Get Data queries to native query language Send query to data source for processing Only the filtered result is returned from the data source 16

13 Preparing for On-premises Power BI

14 Enterprise Connection Options Good News & Better News Source Connection Authentication DAX Compatibility SQL Server DirectQuery Gateway Windows or SQL Server Limited Azure SQL Database Direct Windows/Azure Active Directory or SQL Server SSAS on-premises Gateway Windows/Active Directory Azure SSAS Direct Windows/Azure Active Directory Limited Full (measures in SSAS) Full (measures in SSAS) 18

15 On-premises Data Gateway Download and install from PowerBI.com 8 GB of RAM, 8 core CPU recommended in server mode Runs as service if installed by Administrator Runs as app if installed by unprivileged user Can manage multiple data source connections Used to support: Scheduled refresh Live connect to SSAS DirectQuery

16 Installing and Configuring the Gateway Install Gateway from PowerBI.com Install as Onpremises data gateway or Personal gateway Connect gateway to Power BI tenant 20

19 Direct Connect to Analysis Services On-prem instance Azure SSAS Uses gateway to connect live to an on-premises Analysis Services instance Power BI report visuals connect generate DAX queries Tabular or multidimensional Only query results are sent to the cloud service & not persisted

20 Demo Using Direct Connect to SSAS 25

21 DirectQuery to on-prem databases Sources supported: SQL Server Azure SQL Database Azure SQL Data Warehouse SAP HANA Oracle Database Teradata Database Amazon Redshift* Impala* Snowflake* Live queries are sent directly to the data source DAX queries are translated to the native query language Limited set of DAX functions are supported *in preview as of 2/17/17

22 DirectQuery to on-prem databases Limitations Single database as source Single direction relationships No time-intelligence functions 1 million row query result limit Some Query features & optimizations prevent Query Folding: Using a SELECT statement is a data source Some advanced filter selections Buffering lists Remove rows with errors Koen Verbeeck

23 Demo Using DirectQuery SQL Server data source (DirectQuery) View report Schedule refresh Update source data 29

24 Power BI Embedding Service Separate subscription service Supports report framing in external-facing web application Developers use PowerBI.com Pro subscription Users don t need a subscription Pay-per-use Currently $5 per 100 user sessions (unlimited interactions up to an hour) REST API Programmatic authentication, filters & events Supports DirectQuery data source only 30
