summary

Aeron Cluster (built on Aeron and Aeron Archive) implements a Raft-based replicated log with snapshots and replay, showing region‑wide fault tolerance and practical DR options: cold snapshots in S3, warm standby pulling logs or fully hot DR that flips in seconds. Measured peak throughput reaches 1.8M msgs/s with a sub‑20µs P99 roundtrip. Operational lessons: snapshot frequency vs replay time, asynchronous snapshot dissemination, run 5–7 node clusters for safe rolling upgrades, and version everything for mixed‑version deployments.
