Exploring Axon

Ready to tackle the journey from monolith to microservices? Get some pointers from the pros first! In this episode, Sara is joined by Frédéric Bouvet, a software engineer with 12 years of experience. Frédéric has worked extensively with CQRS (Command Query Responsibility Segregation), DDD (Domain-Driven Design), and event sourcing patterns, particularly in the context of the Axon Framework and Axon Server. The two discuss Frédéric's journey in adopting these patterns, especially in the context of migrating a monolith to a secure microservices architecture at SlimPay, a payment company based in Paris. Frédéric shares insights into his experience with CQRS, emphasizing its benefits for optimizing both reading and writing performance. He explains the challenges of introducing these patterns to a team that was accustomed to CRUD operations, highlighting the importance of knowledge sharing, pair programming, and code reviews in overcoming the learning curve. The conversation delves into the process of migrating from a monolith to microservices, with Frédéric outlining steps such as isolating the domain, breaking external references, and implementing a switch mechanism for data synchronization.  Frédéric also touches upon the challenges of evaluating costs but emphasizes the gains in maintainability and development efficiency.  Overall, the episode provides valuable insights into the practical implementation of CQRS, DDD, and event sourcing in the context of microservices, offering a real-world perspective on the challenges and benefits of such architectural choices.

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.    Connect with Mitchell on LinkedIn.  Connect with Sara on LinkedIn and Twitter.    For more information about us, visit axoniq.io
