Concurrent licenses are a type of software license that revolve around the maximum number of users who will use the software at the same time. For instance, if the organization purchases five concurrent licenses, five of their users can access the same software at any given time. This is particularly useful in enterprises that operate across timezones, where the same software used during work hours will not be needed in California at the same time as London, driving down software operating costs.
In a single device or per seat license model, the business will need to be licensed for each user, meaning multiple users can't share the same license. With a straightforward concurrent model, the business can effectively spread licenses among multiple users, providing they do not need access at the same time.
