This is arguably the "Best Book" written on Domain Driven Design since the seminal book By Eric Evans. I have read both the Red Book and Blue Book. Both the books introduced the Domain Driven concepts and highlighted the salient features and patterns of Application Architecture and advocate the application of DDD patterns for handling complexity in the application domain analysis and application implementation design patterns for elegant solution designy. This books break it down further and shows the nitty gritty of actually applying the concepts introduced in the Red Book and the Blue Book using elaborate and in-depth examples and takes us through the steps of analysing the problem domain, understand and developing the UL and the process of domain analysis using the requirements laid down at the inception of the project. In the subsequent chapters the author provides ways of applying DDD principles using different architectural solution strategies and draws from his experiences to further explain by evaluating and comparing the pros and cons adopting different architectural styles and patterns in his examples. Though the examples are restricted to .NET and Microsoft Technology Stack, they are still easy to follow and understand the essence of applying DDD while designing a software application.
