The Chubby Lock Service, based on the research by Mike Burrows from Google, provides a mechanism for synchronizing activities in loosely-coupled distributed systems. It allows clients to agree on basic information, such as choosing a leader, with the help of advisory locks and event notifications. T

This lecture covers the concept of Paxos and achieving consensus in distributed systems. It discusses the availability of P/B-based RSM, RSM via consensus, the context for today's lecture, and desirable properties of solutions. The analogy of the US Senate passing laws is used to explain the need fo

Consensus algorithms play a vital role in distributed systems like Paxos. Paxos is a protocol that aims to achieve consensus among a majority of participants. It defines roles for nodes like proposers, acceptors, and learners, each serving a specific purpose in reaching agreement on a single value.

Consensus in distributed systems involves getting multiple servers to agree on a state. The Raft Consensus Algorithm, designed by Diego Ongaro and John Ousterhout from Stanford University, aims to make achieving consensus easier compared to other algorithms like Paxos. Raft utilizes a leader-based a

The Raft Consensus Protocol, introduced by Prof. Smruti R. Sarangi, offers a more understandable and easier-to-implement alternative to Paxos for reaching agreement in distributed systems. Key concepts include replicated state machine model, leader election, and safety properties ensuring data consi
