KinderGate Parental Control features clustering support which allows creating a system of several machines that is controlled and operated from the same computer. The cluster consists of a node, nodes replicate settings and their local cache with all the remaining nodes in the cluster. Information on all user requests is stored locally on each server (raw data) and it is not replicated on other servers.
