This configuration involves configuring two or more license servers which must be installed on different devices. The license containers must also exist multiple times and be exclusively accessible to each license server.

. Advantages:
  • Easy configuration

  • Cost-effective

. Disadvantages:
  • Multiple purchases of the same license are necessary (separately for each license server).
