The book is a compendium of architectural patterns which sorts them out into a tree-like hierarchy based on the pattern's structure and function. This allows for grouping hundreds of patterns into less then 20 classes and exploring the common features, applicability, and performance of each class.

It also includes supplementary topics that range from the discussion on the nature of complexity to the comparison of orchestration, choreography, and integration through shared data. Aside of that, there is a wide range of evolutions which show how a system may change under different forces.

The book is AI-free, 440 pages long, and includes hundreds of box-and-arrow diagrams. It can be downloaded from:
