Floating licensing

Floating licensing is a software licensing approach in which a limited number of licenses for a software application are shared among a larger number of users over time. When an authorized user wishes to run the application they request a license from a central license server. If a license is available the license server allows the application to run. When they finish using the application, or when the allowed license period expires, the license is reclaimed by the license server and made available to other authorized users.

The license server can manage licenses over a local area network, an intranet or virtual private network, or the Internet.

Floating licensing, also sometimes known as concurrent licensing or network licensing, is often used for high-value applications in corporate environments, such as electronic design automation or engineering tools. However, its use is now expanding more widely throughout the software industry.

An on-premise license server used to be the only way to enforce floating license models. A license server was required at each end users location and each computer or device in a network needed to connect to it. License files would be bound to the host ID of the license server but could be made available to any client computer in the network, with the concurrent user limit enforced by the on-premise license server. License files are usually tied to the Host ID of the license server by a MAC address or Ethernet address. The number of licenses registered and installed on the license server limits the number of concurrent users.[1]

On-premise license servers are the traditional method of implementing floating, however, modern solutions make use of cloud-based and plug and play solutions.
