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.

Root cause analysis

Root cause analysis is a process that helps you uncover what the original source of the problem was, not only its manifestation. The most common way to perform root cause analysis is to use the method of 5 Whys, which was made famous by the Toyota company. This method consists of peeling off all the superficial layers of the problem's manifestation to uncover the root cause hidden underneath. You do this by asking "why" at each layer until you find the root cause you are looking for.

Let's look at an example of this method in action.

The problem: We didn't get payments for some of the transactions:

  1. Why? The system didn't send the appropriate emails to the customers.

  2. Why? The email sending system doesn't support special characters in customers' names.

  3. Why? The email sending system wasn't tested properly.

  4. Why? There was no time for proper testing due to a need to develop new features.

  5. Why? ...
