In our global enterprise environment we want to have one license server in each region, where every server uses the servers in the other regions as backup.
How does Adobe License Manager support such a design?
Adobe LM supports perpetual license i.e. the Adobe Product talks to license server during activation or return. Once activated, the product does not talk to license server unlike concurrent license model. One can change the server address in license setup file, a small effort. You may install multi-servers (one in each region).
The load balancing is more applicable for concurrent licensing, where the client is in constant communication (sends heartbeat to server).
