Raft consistency algorithm

Introduced:

In the past, Paxos has been the standard of distributed protocols, but Paxos difficult to understand, more difficult to achieve, Google's distributed lock system Chubby as a Paxos implementation has encountered many pits.

The new distributed Protocol study from Stanford, called Raft, is a protocol built for real-world applications that focuses on the floor and the understanding of the Protocol.

The raft protocol is based on the replication state Machine (replicated), where a group of servers executes the same command from the same initial state, in the same order, and eventually reaches a consistent state.
