Presentation: Consensus: Why Can't We All Just Agree?
Share this on:
Abstract
Reaching agreement is never easy and distributed systems are no exception to this rule. In this talk, we take a journey though the history, to the current reality and look ahead to the future for distributed consensus. We start over three decades ago, when the field of distributed consensus began with a proof of its impossibility. We will journey to today’s data centres where algorithms such as Paxos, Zab and Raft provide a fundamental service to widely-adopted distributed systems. Along the way, we'll organizing parliament for a Greek island and debunk widely held beliefs about distributed systems. At the final stop on our journey, we will explore how our recently revised understanding of consensus enables a new generation of scalable yet resilient distributed systems, many of which were previously thought to be impossible to achieve.
