Going back from ABIs to APIs, let's mention one more type that we omitted when we were designing great APIs earlier in this book. The hero of this section can save the day when it comes to optional parameters for functions as it can help your types have components that may or may not hold value, and it can also be used for designing clean interfaces or as a replacement for pointers. This hero is called std::optional and was standardized in C++17. If you can't use C++17, you can still find it in Abseil (absl::optional), or find a very similar version from Boost (boost::optional). A big plus of using those classes is that they express the intent very clearly, which helps with writing clean and self-documenting interfaces. Let's see it in action.

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.
