The Raft Consensus Algorithm

Raft is a consensus algorithm that aims to simplify the understanding of this concept. It is comparable to Paxos in terms of fault-tolerance and performance but differs in its modular structure and comprehensive approach to practical systems. The goal is to make consensus accessible to a wider audience and encourage the development of higher quality consensus-based systems. Consensus is a fundamental challenge in fault-tolerant distributed systems, involving multiple servers agreeing on values that are considered final decisions. Raft achieves consensus through a series of commands in the servers’ logs, ensuring that all state machines progress in the same way. The website provides a Raft visualization and links to publications, talks, and courses related to Raft.
