Raft

Raft is a consensus algorithm used in distributed systems to ensure multiple servers agree on a sequence of actions or data, maintaining consistency even if some servers fail. It orchestrates how leader servers coordinate with followers, handle updates, and recover from failures, making sure all servers stay synchronized. Think of it like a team working together: the leader makes decisions, and everyone follows to keep the group's work consistent and reliable, enabling fault-tolerant and scalable systems such as databases or cloud services.
