Axon Server is a dedicated event store and message routing platform designed for microservices architectures. It provides zero-configuration message routing for commands, events, and queries, and serves as a highly available, infinitely scalable event store. Axon Server enables event sourcing by durably storing events, allowing systems to evolve and scale without complex configuration. It offers real-time observability, graphical management interfaces, and supports bi-directional HTTP/RSocket connections for integration with any programming language. The platform is available in multiple editions, including a free Developer version and an Enterprise edition with advanced features such as clustering, multi-tenancy, and enhanced security. Axon Server is suitable for organizations seeking to simplify distributed system communication and event storage while maintaining high performance and operational insight.
