Raft

A distributed consensus algorithm (Ongaro & Ousterhout, Stanford, 2014), designed to be more understandable than Paxos. Not an acronym — the name was chosen as a humble visual metaphor (a simple floating craft that survives storms), deliberately contrasting Paxos's Greek-island academic vibe. The popular backronym "Reliable, Replicated, Redundant, And Fault-Tolerant" came after the name was chosen.
