Apps are particularly well-suited to large, corporate BI deployments that support the reporting and analysis needs of many users. In most of these scenarios, the great majority of users only need to view certain reports or dashboards and don't require the ability to edit or create any content like Power BI Pro users.

For example, a salesperson within the northwest region of the United States may only briefly access a few dashboards or reports 2 – 3 times per week and occasionally interact with this content, such as via slicer visuals. With the Power BI Premium capacity, these read-only users can be assigned Power BI Free licenses yet still be allowed to access and view published apps. 

In the absence of the Power BI Premium capacity, a Power BI Pro license would be required for each user that needs to access the app. In small-scale scenarios, such as when organizations are just getting started with Power BI, purchasing Power BI Pro licenses for all users can be more cost-efficient than Power BI Premium capacities. However, at a certain volume of users, the Power BI Premium capacity becomes a much more cost-efficient licensing model. Additionally, Power BI Premium enables many other features intended to support enterprise deployments. The details of provisioning and managing Power BI Premium capacity is described in Chapter 13, Scaling with Premium and Analysis Services.
