Three Redundant License Servers

To work with the redundant license model, a License Server pool must to be set up. The primary License Server in the pool is designated as the leader; the remaining License Servers become followers. As long as the primary License Server is running, all the tokens remain with the leader License Server and are not distributed amongst the other License Servers in the pool.

How it works

• A client sends a license request to the primary License Server.

• The primary License Server establishes a connection with the client and grants the license after successful authentication.

• When the primary License Server (leader) is not running, the next leader takes over: the follower License Server having the highest precedence.

• The follower License Server fulfills the new license requests seamlessly (as long as licenses are available).

• If the primary License Server re-starts, it reclaims leadership and license control is transferred back to the primary License Server.
