The licensing for SharePoint 2013 is a bit confusing, but I think I understand most of it.
All of our users are internal, so I need CALs for them. We want to use enterprise features, so I need to add an additional Enterprise CAL for each user.
Microsoft's site states that a server license is required for each server running an instance of SharePoint. Our farm configuration consists of 2 Web Front End (WFE) servers, 3 Application servers, 2 Index servers, and potentially 1 crawling server.
My question is, do all 7/8 servers require a SharePoint 2013 server license? Do just the WFEs?
