Long path to better systems that last longer and make engineers and customers happierThis book is a comprehensive guide to designing scalable and maintainable software written by an expert. It covers the principles patterns antipatterns tradeoffs and concepts that software developers and architects need to understand to design software that is both scalable and maintainable.The book begins by introducing the concept of monoliths and discussing the challenges associated with scaling and maintaining them. It then covers several antipatterns that can lead to these challenges such as lack of isolation and internal shared libraries.The next section of the book focuses on the principles of good software design such as loose coupling and encapsulation. It also covers several software architecture patterns that can be used to design scalable and maintainable monoliths such as the layered architecture pattern and the microservices pattern.The final section of the book guides how to migrate monoliths to distributed systems. It also covers how to test and deploy distributed systems effectively.WHAT YOU WILL LEARN Understand the challenges of monoliths and the common antipatterns that lead to them. Learn the principles of good software design such as loose coupling and encapsulation. Discover software architecture patterns that can be used to design scalable and maintainable monoliths.
