As per Microsoft: a cloud-based business intelligence service that gives people a powerful new way to work with data in the tools they use every day, Excel and Office 365. With Excel you can now discover, analyze, and visualize data like never before to find valuable business insights. With Power BI for Office 365 you can easily deploy a cloud-based BI environment. Couple of features that I would like to mention here:

Quickly create collaborative BI sites – enable anyone to quickly create a collaborative BI site to share workbooks containing data and insights.

Keep reports up to date with scheduled data refresh.
