Welcome to Aeron Cookbook — introducing Aeron, Aeron Archive and Aeron Cluster to new and intermediate users through in depth guides and a cookbook.

Aeron offers efficient reliable UDP unicast, UDP multicast, and IPC message transport — with a core design goal of reaching the highest throughput with the lowest and most predictable latency of any messaging system. Aeron Archive allows message streams to be recorded to persistent storage for later, or real-time, replay. Aeron Cluster provides fault-tolerant total ordering across multiple streams. Aeron is an open source project, hosted on GitHub.

The Aeron® Cookbook is now part of, sponsored by Adaptive. Related source code can be found on GitHub.

If interested, you can join the Aeron mailing list to keep up-to-date with the latest news and events.
