What is a “concurrent” license?
Often the number of users who have access to a product and the number of users who use it are not equal. Provided that the number of users who are using the software at one time does not exceed the number of licenses, the customer can license exactly the number of users who will be accessing it at one time. This is commonly referred to as concurrency.
A concurrent license allows for installation of the licensed product on more than one machine. The restriction is that at any given time there may be no more copies in use greater than the number of concurrent licenses purchased. For example, if you purchase 2 concurrent licenses, you could install the product on 3 or more machines as long as there are never more than 2 copies in use at any one given time. As you might expect, these are typically priced higher than a normal (single) license.
