Distributed System Visualizer

A visual simulation of distributed system concepts including replication, quorum, node failure, and recovery.

Overview

This project demonstrates how distributed systems maintain availability and consistency when nodes fail.

Users can interact with a cluster of nodes and simulate:

• Data replication • Quorum-based operations • Node failures • Node recovery • Cluster health monitoring

Features

Replication

Values written using PUT are replicated across multiple nodes.

Quorum Consensus

Operations require a minimum number of active nodes.

Example: 3 nodes → quorum = 2

Node Failure Simulation

Nodes can be intentionally failed to observe system behavior.

Node Recovery

Failed nodes can be restored to the cluster.

Cluster Health Monitoring

Displays:

• Active nodes • Failed nodes • Required quorum • Total keys stored

Activity Log

Logs all operations including:

• PUT • GET • Node failures • Node recovery
