Software Architecture with C++

By: Adrian Ostrowski, Piotr Gaczkowski

Overview of this book

Software architecture refers to the high-level design of complex applications. It is evolving just like the languages we use, but there are architectural concepts and patterns that you can learn to write high-performance apps in a high-level language without sacrificing readability and maintainability. If you're working with modern C++, this practical guide will help you put your knowledge to work and design distributed, large-scale apps. You'll start by getting up to speed with architectural concepts, including established patterns and rising trends, then move on to understanding what software architecture actually is and start exploring its components. Next, you'll discover the design concepts involved in application architecture and the patterns in software development, before going on to learn how to build, package, integrate, and deploy your components. In the concluding chapters, you'll explore different architectural qualities, such as maintainability, reusability, testability, performance, scalability, and security. Finally, you will get an overview of distributed systems, such as service-oriented architecture, microservices, and cloud-native, and understand how to apply them in application development. By the end of this book, you'll be able to build distributed services using modern C++ and associated tools to deliver solutions as per your clients' requirements.

Optimizing whole programs

An interesting way to increase the performance of many C++ projects is to enable link-time optimization (LTO). During compilation, your compiler doesn't know how the code will get linked with other object files or libraries. Many opportunities to optimize arise only at this point: when linking, your tools can see the bigger picture of how the parts of your program interact with each other. By enabling LTO, you can sometimes grab a significant improvement in performance with very little cost. In CMake projects, you can enable LTO by setting either the global CMAKE_INTERPROCEDURAL_OPTIMIZATION flag or by setting the INTERPROCEDURAL_OPTIMIZATION property on your targets.

One drawback of using LTO is that it makes the building process longer. Sometimes a lot longer. To mitigate this cost for developers, you may want to only enable this optimization for builds that undergo performance testing or are meant to be released.
