#71 - Strategic Monoliths and Microservices - Vaughn Vernon

“Strategy is what earns. Use the strategic and innovative drivers to help us determine what our architecture needs to be. Architecture has to have a purpose."

Vaughn Vernon is a leading expert in Domain-Driven Design (DDD) and he recently co-authored his new book “Strategic Monoliths and Microservices”. In this episode, Vaughn shared his story and rationale for writing his new book and why he thinks it is important to include the executives as the readers of the book. He emphasized the importance of focusing on strategic innovative aspects of software development and for driving those innovations using purposeful architectures. Vaughn then shared his insightful perspective on Conway’s Law and why he compares it with the law of gravity. We then discussed two important architectural aspects covered in the book, which are events first architecture and embracing latency, and why they are actually natural to how people communicate and get things done in real life. Towards the end, Vaughn summed up his book and left an important piece of advice that he wanted to convey regarding monoliths vs microservices and why software should require more balance and demand a better strategy.
