Turning data into business insights is challenging

Common BI challenges include…

Multiple data sources Data residing in SaaS solutions, and other external locations, is difficult to access and refresh securely

End-to-end view Data often resides in disparate locations, making it difficult to see a complete picture of your business

Right data for the right users at the right time

Different roles have different needs, and business users need the latest operational data

Embedded ScenariosFully interactive reports that were authored in the Power BI Desktop can be embedded within your own application using a new application token authentication model.


@microheather

Embedded ScenariosIndependent software vendors and customers building customer facing applications can use the Power BI Embedded service, and the Power BI SDK, to embed interactive reports.


@microheather

Embedded ScenariosAs a developer, you can use the Power BI visualization framework to create custom visualizations that can be used in your own app.


@microheather

What are the differences Integrating Power BI requires the following:

AAD app registration

requires users to login with o365 credentials

Blog post: http://www.mostafaelzoghbi.com/2016/04/integrate-power-bi-report-into-app.html

Power BI Embedded: No login is needed for Users

No AAD app registration


@microheather


@microheather

HOW IT WORKS

Authenticating and Authorization The Power BI Embedded service uses Keys and App

Tokens for authentication and authorization, instead of explicit end-user authentication.

Two Ways to authenticate Keys: From Power BI Embedded in Azure Portal (Access Keys)

App Token: are used for all embedding requests. They’re designed to run client-side so they’re restricted to a single report. App tokens are JWT (JSON Web Token) that is signed by one of your keys.


@microheather

Getting Started Azure subscription

Provision a “Power BI Workspace Collection” from Azure portal

Create a workspace into Power BI workspace collection

Import a (.pbix) report file into a workspace

Embed a report with one html tag into your application
