The project is simplified-Big problems are cut into more manageable problems that you can focus on.Thinking about software in this way provides a couple of advantages: It also acts as the conceptual foundation for the design of the software itself-how it’s broken down into objects or functions.” Figure 1. A model acts as a Ubiquitous Language to help communication between software developers and domain experts. “DDD is about designing software based on models of the underlying domain. Martin Fowler explains how DDD helps solve these problems (see Figure 1): Controlling inherent project complexity-Like Paul Graham says, you are trying to solve something so complex that your competitors don’t figure out how to outrun you in the market.By cutting corners, you may win market share but the project can grow into what is often referred to as a “ big ball of mud,” which is “a haphazardly structured, sprawling, sloppy, duct-tape and bailing wire, spaghetti code jungle.”

Minimizing technical debt-By developing in a way that is easy in the short run but complex in the long run, you may be creating a minimum viable product (MVP).

Why DDD is worth itĭDD is most effective at doing two things: Instead, we will focus on how it can be used to architect cloud applications-specifically how to integrate it into existing stacks, and especially how it can help you build powerful event-sourcing systems. You can learn a lot more online about it than we can cover in one tutorial, so we won’t dive too deep into the theory and roots of DDD.

Domain-driven design (DDD) is a set of strategies and tools that can help you design systems and manage complexities.
