How do Telerik Report Server Licenses Work?

The Telerik Report Server is licensed per instance based on a "per public domain" exposure, with development and staging installations included. You can also establish a fail-over instance, so long as both instances do not run simultaneously. The instance license provides 15 Client Access Licenses (CALs), and additional bundles of 5 are available for purchase.

Any end user who directly accesses the Report Server website to navigate the tabs, access categories that house reports, or who would request to view a report by clicking on a report link and viewing it within the integrated HTML5 Report Viewer in a web page would need to be assigned one of the CALs and an associated login. CALs must be assigned to anyone designated with a role of Server Administrator, Data Administrator, Report Viewers, or Report Creator (Editor). That means anyone who uses the integrated report designer also needs a CAL. CALs are not floating and do not simply cover the current 15 active users. They are directly assigned to a user of the server.
