demo DMG IN ACTION

Data Source Discovery  Data Sources are declared on « Admin Center »  They are associated to a Gateway  Gateway Cloud Service resolves Data Source and find right Gateway  Resolution = Provider + Server + Catalog  Warning: Case sensitive

Identity Management 2 flavors :  Impersonation by DMG  Impersonation by Data Source How is query authentified on Data Source ?

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

demo CREDENTIAL MANAGER

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

demo EffectiveUsername

HIGH AVAILABILITY & DISASTER RECOVERY

As easy as scale-out DMGs Cloud On-Prem Power BI … Instance 1 Instance 2 Server A Server B

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

demo HA & DR

Going further  Express Route  Mashup Container (aka Power Query)  Monitoring & Logging
