Microsoft announce that Power BI Embedded is generally available. Be aware that this is a cousin rather than a brother of the Power BI service licensed with Power BI User Subscription Licences.
Power BI Embedded is an Azure consumption service (charged as users interact with reports) and intended for ISVs who embed dashboards in applications for third party use.
