Architect high-quality C++ applications using modern features and patterns, with expanded coverage and practical new examples throughout the book. Free with your book: DRM-free PDF version + access to Packt's next-gen Reader* Key Features Design modern C++ systems using features from C++11 through C++20 and beyond Explore distributed system design with observability, scalability, and maintainability in mind Manage and package C++ applications, and prepare them for deployment using CMake, Conan, and CI/CD Book Description Designing scalable and maintainable software with C++ requires more than language expertise—it demands strong architectural thinking. This practical guide equips you with the skills to design and build robust, distributed systems using modern C++. Starting with fundamental architectural principles and design philosophies, the book walks you through practical approaches to designing and deploying reliable systems. This edition contains significant updates across the book, including new chapters on observability, package management, and C++ modules to address real-world software challenges. You will explore software decomposition strategies, design and system patterns, fault tolerance, API management, and testability—all applied with C++. Additionally, the book covers modern CI/CD pipelines, cloud-native design, microservices, and modular development, helping developers navigate today's fast-evolving software landscape. With updated examples and a renewed emphasis on maintainable and observable architectures, this edition equips C++ professionals to architect modern systems. By the end of this book, you will be able to design, build, test, and deploy well-architected solutions using modern C++ and proven architectural techniques. *Email sign-up and proof of purchase required What you will learn Apply architectural fundamentals to design scalable C++ systems Use modern C++ features to create maintainable and secure applications Implement architectural and system design patterns Design testable code and automate quality checks via CI/CD pipelines Manage dependencies and build systems using CMake and Conan Explore microservices, containers, and cloud-native practices in C++ Improve observability with logging, tracing, and monitoring tools Build deployable C++ systems suited for modern development environments Who this book is for This book is intended for experienced C++ developers and software engineers aiming to expand their architectural knowledge, lead software projects, or build scalable systems.
