SharePoint Integrated mode
In SharePoint mode, a Report Server must run within a SharePoint Server (even
in a standalone implementation). The Report Server processing, rendering, and
management are all from SharePoint application server running the Reporting
Services SharePoint shared service. For this to happen, at SQL Server installation
time, the SharePoint Integrated mode has to be chosen. The access to reports and
related operations in this case are from a SharePoint frontend.

The following elements are required for SharePoint mode:

• SharePoint Foundation 2010 or SharePoint Server 2010
• An appropriate version of the Reporting Services add-in for
SharePoint products
• A SharePoint application server with a Reporting Services shared service
instance and at least one Reporting Services service application

The following diagram taken from Microsoft documentation illustrates the various
parts of a SharePoint Integrated environment of Reporting Services. Note that the
alerting Web service and Power View need SharePoint Integration.
