Over more than 15 years ago, Eric Evans published the book Domain-Driven Design. The blue book, as it is called today, has a vast amount of knowledge on software architecture. As Paul Rayner once stated 'Every new idea on software architecture; you can already find somewhere in the blue book'. Because the knowledge is so fast to take in at one go, a lot of people who bought the book never finished the book, mostly stopped reading before Part IV, strategic design. Therefore in this #VDDD special 'How to read the blue book,' Mathias Verraes will discuss with the strategic parts.
