Unity Enterprise licensing comes in two primary forms; Floating and node-locked.
Floating licenses give you the flexibility of a true check-in and check-out style of licensing. When a user opens Unity, they are automatically assigned a license. When that same user closes Unity, the license is released automatically. The floating licenses live on an on-premise server controlled by a server admin instead of the Unity cloud. This server needs to be maintained and regulated by the server admin.
Node-locked licenses are managed on the Unity website. You can manually send and revoke licenses from named users from the website. Every user is required to have a free Unity account to get a license. While node-locked licenses can be moved around by the customer, it requires manual intervention compared to floating licenses.
Floating licenses are only recommended if your company has a centralized IT team to manage and maintain the license server. If your company has a dedicated set of Unity users using the software regularly, node-locked licenses are typically the better licensing option. It’s also possible to simultaneously have a mix of node-locked and floating licenses.
