Tiered Storage in Axon Server

Let's face it – the concepts we use everyday are complex. While CQRS, DDD, and other architectural patterns may be 20+ years old now, anyone who's learned them can tell you that it takes a while to get the hang of it. Today, Sara speaks with Jaroslav Schnaubert of ASSIST on strategies to ease the learning curve – from breaking down the process and restructuring your mindset when learning new concepts in software development.

In this episode, Sara is joined by Emilien Pecoul – software developer, architect, and entrepreneur.  They discuss the benefits of using patterns such as domain-driven design (DDD), event sourcing, and Command Query Responsibility Segregation (CQRS) in startup companies and for freelancers looking for their next project. Emilien shares insights into his background as a freelancer and entrepreneur, emphasizing the importance of learning and adopting effective software development practices. He discusses how he started as a freelancer in 2013, facing challenges in finding companies aligned with his preferred working practices. He highlights the role of meetups and conferences in connecting with like-minded developers – and about his work with his start-up, "The Actual Job," to help mentor full-time developers in their journey to become freelancers. The discussion expands to cover the significance of DDD, with Emilien sharing his journey in understanding and implementing DDD principles. He acknowledges the initial difficulty in grasping DDD concepts but emphasizes the value it brings to building robust software. The interview explores the complexities of domain-driven design, especially in translating abstract concepts to practical implementations. They go on to talk about how these concepts translated into the realities of Emilien's daily life at his freshly created start-up. The interview concludes with insights into the importance of understanding why and how to implement certain patterns, adapting strategies based on project requirements, and making informed decisions to avoid unnecessary complexity.

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.
