#21 - Domain-Driven Design and Event-Driven Architecture - Vaughn Vernon

“Programmers have to come out of their cubicles. Innovative software development doesn’t happen with one person in a cubicle with great ideas. Because it’s not just even about code. Anybody can write code. It’s about what does the code accomplish. And if the code accomplishes something innovative, great!" Vaughn Vernon is a leading expert in Domain-Driven Design (DDD) and reactive software development. He is well-known for his best-selling DDD books and IDDD workshops. In this episode, we discussed many things about Domain-Driven Design and Event-Driven Architecture (EDA). Apart from the fundamentals, Vaughn shared many of his insights around the two, such as why developers should learn more about DDD, the most important aspect of DDD, the benefits of EDA, eventual consistency, event storming, and event sourcing. Towards the end, Vaughn also gave a sneak peek about his new book “Strategic Monoliths and Microservices” and why he wrote it.
