Model Mitosis: Stop Making the Wrong Choice Between Microservices and Monolith

This conference talk explores the iterative nature of software design and how it should adapt as context and understanding evolve. Learn how to identify when a growing software system reaches critical mass and becomes an unwieldy monolith of spaghetti code. Discover the Model Mitosis approach, a dynamic method for splitting business models into multiple components that can be shaped and decoupled iteratively. Gain practical insights on finding the right boundaries for modularization, determining the optimal timing for splitting into modules or services, and managing the progressive differentiation of business models while avoiding unnecessary coupling. This 46-minute Devoxx presentation by Topçu and Chevalier offers a flexible approach that helps developers make better decisions about when to split into multiple services, avoiding both the scaling costs of microservices and the pitfalls of distributed monoliths.
