Quorum & Replication Visualizer

Configure N, W, R. Simulate failures, test consistency.

Configure N (replicas), W (write quorum), R (read quorum). Click nodes to simulate failures. See if consistency and availability hold.

💡Configure replicas (N), write quorum (W), and read quorum (R). Kill nodes to test consistency and availability.

N (replicas)

W (write quorum)

R (read quorum)

Strong Consistency (W+R>N)

3+3=6 > 5 — YES

Read and write quorums always overlap — reads always see latest write.

Availability (0 nodes down)

Write: OK · Read: OK

5 of 5 nodes alive. Need 3 for writes, 3 for reads.
