Introduction
Axon Server is our custom-built scalable and highly available event store and message delivery system, which coordinates the communication between components, considering the expectations for each type of message: commands, events, and queries. This allows systems to evolve as their functional or technical needs change over time. Furthermore, Axon Server can track all changes as a reliable source of truth, guaranteed to contain the whole truth and nothing but the truth.
