Domain-Driven Design (DDD) is a fancy way of saying, “Let’s keep things aligned with the real business needs,” but it’s much more than that. At its heart, DDD is about creating software that mirrors the core concepts of the business itself, constantly evolving with it. Now, when you take this approach and apply it to microservices, magic happens. DDD gives you a structured blueprint to design microservices that aren’t just another piece of tech but actually resonate with how the business operates. It’s all about designing services around the business domains, which makes the whole system more flexible and easier to maintain.
