C++ Application Architecture: From Project to Production

The book "C++ Application Architecture" is a practical guide for developers who want to move from writing "working" code to creating industrial systems that are resilient to change and easy to maintain. The author, Alexey Voronov, shares years of experience in designing high-load C++ projects and offers ready-made architectural solutions that can be applied to real-world tasks.

What this book is about

The book covers the full cycle of C++ application development — from choosing an architectural style to organizing testing and refactoring. You will learn:

• How to apply the SOLID, DRY, and KISS principles in the context of C++
• Which design patterns (GoF, GRASP, architectural) are most effective in C++
• How to build a modular architecture considering language features: RAII, smart pointers, move semantics
• How to organize multithreading and avoid data races, deadlocks, and performance issues
• How to design APIs and interfaces for easy testing and extensibility
• How to refactor legacy code without the risk of "breaking" the system
• How to integrate unit tests, integration tests, and performance tests into the architecture

Who this book is for

The book is aimed at C++ developers of middle level and above who already know how to write code but want to learn how to design systems. It will be useful for:

• Programmers working on large projects facing maintenance and scaling challenges
• Team leads and architects looking for proven approaches to code organization
• Developers transitioning from other languages to C++ and wanting to understand its strengths in architecture

What you will gain

After reading, you will be able to:

• Make informed architectural decisions rather than blindly following patterns
• Build applications that are easy to test, extend, and maintain
• Avoid common mistakes when designing multithreaded and distributed systems
• Confidently work with legacy code and improve its architecture without a complete rewrite

The book contains numerous code examples, diagrams, and practical exercises. All examples are tested on modern C++17/20 compilers and are ready for use in real projects.
