Without DDD, microservices often devolve into a "distributed monolith," where services are tightly coupled and constantly breaking. By using Evans' concept of , engineering teams can perfectly align microservice boundaries with clear business capabilities. This ensures that teams can build, deploy, and scale their services independently without stepping on each other's toes.
By exploring these resources and applying DDD principles, developers can take their software development skills to the next level and create systems that truly meet the needs of their users. domain driven design eric evans ebook pdf 51
