Anyone that has been involved with software license enforcement over the last 20 years will almost certainly have heard of floating licenses. The concept of a centralized license manager serving licenses out to waiting applications on a first come first served basis is pretty well known and understood. But as soon as you start thinking about that deployment model, you will probably start thinking about failure: failure of the license manager, failure of the network, failure of the software. When you have license manager providing centralized license control, you have a single point of installation, a single point of administration and a single point of failure. One crash, and hundreds, maybe even thousands of innocent workstations can’t get a license anymore. Work grinds to a halt. It sounds serious, right? Yet this is one of the most commonly ignored gremlins in software licensing.
