A single license can be used to activate PowerServer on as many server instances as you would like, provided that:

  • Those server instances are used solely for your internal business purposes by your employees, agents and contractors, unless otherwise permitted by the type of license purchased; and
  • The number of user sessions across all servers does not exceed the licensed capacity.

    So generally, most customers just need a single license. However, if you want to limit how the user sessions are distributed across multiple server instances, then you should consider to purchase multiple smaller licenses.
