The article by Paul Dix from DZone discusses the concept of the "Decomposable Monolith," a design/architecture pattern that allows for easy transition to services-based development, even when starting with a monolithic architecture. The Decomposable Monolith is proposed as a way to structure new projects in a modular and serviceable manner, enabling easier scalability and maintainability. By using this approach, developers can create applications that can be broken down into smaller, independent services, making it simpler to adopt a services-based development model.
