A site license is an agreement entered into by the University of Guelph and a vendor in which individuals or groups associated with the University of Guelph are given access to a particular piece or suite of software in return for an annual or one-time license fee. There are four mechanisms used to administer software licensing at the University of Guelph. They are:
Concurrent licensing allows members of the University of Guelph an extremely cost effective way to share a fixed number of software license. Under this type of licensing arrangement, software can be installed on any number of computers, provided that the actual usage of an application does not exceed the number of licenses owned.
A license server keeps track of how many licenses are in use at one time. When an application using concurrent licensing starts, it first checks to see if a concurrent license is available to use. The application using concurrent licensing requires an internet connection.
In Perpetual Licensing, members of the University of Guelph would buy perpetual license to the product and then pay for upgrades yearly to receive new versions.
In Standalone Licensing, users get the security key when they purchase the product and they have to enter the security key to make the software work.
In Subscription Based Licensing, users have to pay monthly or annually to use the software.
