- 29. Identity Management 2 flavors : Impersonation by DMG Impersonation by Data Source How is query authentified on Data Source ?
- 30. Impersonation by DMG Connection identity is impersonated by DMG Peer-to-peer connection Credentials are stored by DMG for each source Credentials can be stored encrypted locally Credentials can be stored encrypted on Cloud Credentials are set up locally Credential Manager is a Click Once application Credential Manager discuss with DMG
- 32. Impersonation by Data Source Used by Live Query Keep identity of original user Use the EffectiveUsername method DMG authenticates to SSAS DMG passes EffectiveUsername property SSAS executes the query as if it was original user DMG must be SSAS Admin
- 34. HIGH AVAILABILITY & DISASTER RECOVERY
- 35. As easy as scale-out DMGs Cloud On-Prem Power BI … Instance 1 Instance 2 Server A Server B
- 36. HA & DR Gateways and Data sources are managed by Cloud Credentials are encrypted by MDG Use of Certificate, self-generated or yours Need Certificate when registering a new instance Warning when stored localy Load Balancing

Editor's Notes
- #6: -Cloud First Strategy, just listen to Satya -Innovation is in the cloud -Examples : PBI, AzureML, HDInsigth, etc. -If you want new technologies you probably will have to use a cloud-based one -But…
- #7: -you can put all your data assets in the cloud, even, -that will take a long time -or it won’t never happen (mindset, investment, legal constraints, privacy…) -So what -Microsoft knows about that -They build hybrid cloud, hybrid solutions -They make investments in a technology to remove barriers
- #8: -Data Management Gateway -it is the link between Cloud technologies and On-Prem Data
- #10: -first, data refresh is trivial. Models are in the cloud, Data is on-prem. -second, indexing data sources into data catalog -third, relating Data Catalog, agnostic access to Data
- #11: -
- #13: Initiated by Cloud Otherwise, there is no challenge, you can push data from On-Prem (SSIS, Power BI API, etc.)
- #16: ADF & Power BI merged in march
