An introduction to Raft
Let's investigate why the Raft algorithm was created when there was already a Paxos algorithm for solving the consensus problem.
Motivation
Paxos has been the canonical solution to the consensus problem. However, the initial specification of the algorithm did not cover some aspects that were crucial in implementing the algorithm in practice, some of these aspects were covered in subsequent papers.
The Paxos algorithm is also widely considered hard to understand.
