At the base of Redis replication (excluding the high availability features provided as an additional layer by Redis Cluster or Redis Sentinel) there is a very simple to use and configure leader follower (master-slave) replication: it allows slave Redis instances to be exact copies of master instances. Failure reports are the way Redis Cluster uses in order to promote a PFAIL state, that means a node is not reachable, to a FAIL state, that means that the majority of masters in the cluster agreed within a window of time that the node is not reachable.
