Get Your Hands Dirty on Clean Architecture

By: Tom Hombergs

Overview of this book

Building for maintainability is key to keeping development costs low and processes easy. The second edition of Get Your Hands Dirty on Clean Architecture is here to equip you with the essential skills and knowledge to build maintainable software. With this comprehensive guide, you’ll explore the drawbacks of conventional layered architecture and the advantages of domain-centric styles such as Robert C. Martin's Clean Architecture and Alistair Cockburn's Hexagonal Architecture. Then, you’ll dive into hands-on explanations on how to convert hexagonal architecture into actual code. You'll learn in detail about different mapping strategies between the layers of hexagonal architecture and discover how to assemble the architectural elements into an application. Additionally, you’ll understand how to enforce architecture boundaries, which shortcuts produce what types of technical debt, and how, sometimes, it is a good idea to willingly take on those debts. By the end of this second edition, you'll be armed with a deep understanding of the hexagonal architecture style and be ready to create maintainable web applications that save money and time.

It Makes Parallel Work Difficult

Management usually expects us to be done with building the software they sponsor at a certain date. Actually, they even expect us to be done within a certain budget as well, but let's not complicate things here.

Aside from the fact that I have never seen "done" software in my career as a software developer, to be done by a certain date usually implies that we have to work in parallel.

Probably you know this famous conclusion from "The Mythical Man-Month," even if you haven't read the book:

"Adding manpower to a late software project makes it later" – The Mythical Man-Month: Essays on Software Engineering by Frederick P. Brooks, Jr., Addison-Wesley, 1995.

This also holds true, to a degree, to software projects that are not (yet) late. You cannot expect a large group of 50 developers to be 5 times as fast as a smaller team of 10 developers in every context. If they're working on a very large...
