Sara spoke with Spring developer advocate Josh long. Josh talked about his days pre-Spring and why he decided to join the team at Spring.io. He also talked about the reasons why he has stayed with the team and what excites him about the community. Sara asked Josh how he learned about Axon, what that relationship has been, and why he and Allard Buijze wrote the Spring Autoconfiguration for Axon Framework. They then discussed Domain-Driven Architecture, CQRS, Event-Driven Architecture, and how these patterns can help developers.

Introducing ”Inspector Axon”
Friday Mar 03, 2023
Friday Mar 03, 2023
Sara spoke with a colleague, Mitchell Herrijgers, one of Axon Framework's engineers and one of AxonIQ's Solutions Architects. Mitchell has been leading a project for a tool internally called "Inspector Axon." This tool helps developers monitor various things within their Axon Framework-based application and gauge metrics, find out about various event processors, and much more. The name will most likely change once it is publicly available, but for now, we are referring to it as "Inspector Axon."
Mitchell also worked on a different project last year: the IntelliJ plugin for Axon Framework. He also briefly talked about that at the end of the session.
If you are interested in becoming one of our private beta testers for Inspector Axon, please watch our social media for an announcement, or you can reach us through our website.
