Proven technology for DDD / event-sourcing / CQRS systems

Axon Framework is built on sound architectural principles, such as DDD and CQRS. CQRS is an architectural pattern that describes a clear distinction between two parts of an application: one that processes commands and one that executes queries on data. Separating these two domains enables developers to build less complex and better maintainable applications. Axon Framework enables developers to easily develop their applications following this pattern without worrying about the non-functional aspects of messaging between components.

Supports evolutionary approach to Microservices

Location transparency is vital when it comes to designing application components. By ensuring components are unaware of the components they interact with, evolving a monolith into microservices becomes as easy as configuring different messaging components. Axon provides these components, allowing them to scale seamlessly from a single monolith to hundreds of microservices. Axon Framework allows an application to scale when the non-functionals require so, and not a moment sooner.

Focus on business logic

Axon Framework provides the building blocks for components to communicate and simple to use API for configuring it. This allows developers to spend time on what's truly important: the business logic that sets you apart from your competition. As an application evolves, Axon ensures logical boundaries are maintained so that an application remains its ability to scale out when the non-functionals require it.

Integrates with Spring Boot and other frameworks

Axon Framework comes with a Spring Boot Starter, making using it as easy as adding a dependency. Axon will automatically configure itself based on best practices and other dependencies you have set. Providing explicit configuration is a matter of adding a bean of the component that needs to be configured differently. Furthermore, Axon Framework integrates with Spring Cloud Discovery, Spring Messaging, and Spring Cloud AMQP.

Open Source

Axon Framework is free. Axon's sources are available in a Git repository on GitHub. The fast-growing community of Axon users provides support (obviously, at AxonIQ, we're also happy to help).
