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.

Building an example CD pipeline

Let's put all of these skills together once again using the GitLab CI as an example to build our pipeline. Following the testing step, we will add two more steps, one that creates the package and another one that uses Ansible to deploy this package.

All we need for the packaging step is the following:

# Package the application and publish the artifact
package:
stage: package
# Use cpack for packaging
script:
- cd build
- cpack .
# Save the deb package artifact
artifacts:
paths:
- build/Customer*.deb

When we add the package step containing artifacts definitions, we'll be able to download them from the dashboard.

With this, we can invoke Ansible as part of the deployment step:

# Deploy using Ansible
deploy:
stage: deploy
script:
- cd build
- ansible-playbook -i localhost, ansible.yml

The final pipeline would then look like the following:

cache:
key: all
paths:
- .conan
- build

default:

stages:
