    25== Supported Topologies ==
    36This section describes HA topologies which are to be supported by Kea running in different HA configurations. The most common topologies involve two servers running in ''load balancing'' or ''hot-standby'' mode and their variations. The servers utilize the control channel to communicate with each other and don't need to use SQL database replication to synchronize the lease database. Therefore, this solution works for any lease database backend, although Memfile will have the best performance as it doesn't require communication with the external database. The performance impact is important because the Kea servers send lease updates synchronously.
