Guided Lab Brief

Consensus & Coordination Control Plane

Build a leader/follower coordination flow with explicit quorum registry and election control.

Start LabReview ChapterBrowse Guided Labs

Overview

Build a leader/follower coordination flow with explicit quorum registry and election control.

Consensus is about who is allowed to decide.

You will build 6 architecture steps that model production dependencies.

You will run 1 failure experiment to observe bottlenecks and recovery behavior.

Success target: Leader failover occurs within target window while preserving ordered replication semantics.

Learning Objectives

  • Can explain practical consensus control-plane components
  • Can defend quorum/election tradeoffs under failures
  • Can discuss leader failover timing in interviews

Prerequisites

  • Topic Hub: leader election
  • Chapter 25: Consensus
  • Prior Lab: Database Replication & Read Scaling

Experiments

  1. Increase failover time to simulate prolonged unavailability after leader failure

Failure Modes to Trigger

  • Trigger: Increase failover time to simulate prolonged unavailability after leader failure

    Observe: Write path stalls too long after leader loss, violating availability targets.
