Description

When should I cluster licenses?

Under normal circumstances, a License Cluster contains a single License object in its licenses array. However, particularly when dealing with upgrades, clustering multiple related licenses may be useful.

For example, consider a hypothetical Plug-In called 3D Donuts. There are licenses for 3D Donuts version 1, and licenses for 3D Donuts version 2.

The Donuts software license agreement can describe one of the following three scenarios:

  1. After upgrading to version 2, users can run version 1 and version 2, but not concurrently.

    In this scenario, it makes sense to cluster the version 1 license and the version 2 license. To do this, simply return a license cluster with both License objects. Cloud Zoo will automatically replace the existing version 1 license cluster with the new one passed. Users now have a single seat (Unless numberOfSeats is greater than 1) to share between version 1 and version 2. If the licenses in the cluster have an expiration date, the exp field of the first license in the array will be assumed to be the expiration date for all licenses. Similarly, the numberOfSeats field of the first license will apply to all licenses in the cluster, regardless of the value of their numberOfSeats field.

  2. After upgrading to version 2, users can run version 1 and version 2 concurrently.

    In this scenario, it is advisable not to cluster licenses, but to treat them independent of each other–even if the version 1 license is required initially to add the version 2 license. Users will be able to run version 1 and version 2 concurrently.

  3. After upgrading to version 2, users can no longer run version 1.

    This scenario is similar to scenario #2, but after adding a license, the issuer must manually call the DELETE endpoint to remove version 1 from an entity.
