TrainingAxon Server is our in-house specialized event store and message delivery system. It offers superior scalability and throughput characteristics without requiring complex tuning. As our flagship product, it comes in two variations: standard and enterprise functionality.
Message routing and event store in one
Axon Server is freely available to get started quickly and easily. Various other options are available for serious enterprise deployments to give you the assurance and functionality you need. The Enterprise functionality adds SLA-backed support, clustering, monitoring, and integration features to the free Axon Server – ensuring your application is ready for enterprise deployment. Expansion packs are available for security and compliance, global multi-data center deployments, and big-data applications.

Zero configuration management
Microservices systems are often associated with complex configuration management. Setting up service discovery and message routing correctly is a time-consuming and error-prone task. Axon Server eliminates this complexity. Because it’s built for a purpose, it performs service discovery and message routing with zero configuration. It just works.
Real-time insight
In a complex microservices system, it can be hard to understand “what’s going on” when teams need to debug a problem. Axon Server helps: it automatically provides a graphical overview of our landscape, with drill-down functionality to get detailed information about message handlers. Also, it allows you to do ad hoc querying on events, extracting specific information from JSON or XML event payloads.
Easy scale-out
As your application becomes more successful, you may need to scale your service components horizontally. Axon Server makes it easy: spin up new instances, and Axon Server takes care of the rest. It detects multiple copies of the same service and deals with this correctly for commands, events, and queries. No matter whether you have two instances or 50.
