Software Architecture with C# 9 and .NET 5 - Second Edition

By: Gabriel Baptista, Francesco Abbruzzese

Overview of this book

Software architecture is the practice of implementing structures and systems that streamline the software development process and improve the quality of an app. This fully revised and expanded second edition, featuring the latest features of .NET 5 and C# 9, enables you to acquire the key skills, knowledge, and best practices required to become an effective software architect. This second edition features additional explanation of the principles of Software architecture, including new chapters on Azure Service Fabric, Kubernetes, and Blazor. It also includes more discussion on security, microservices, and DevOps, including GitHub deployments for the software development cycle. You will begin by understanding how to transform user requirements into architectural needs and exploring the differences between functional and non-functional requirements. Next, you will explore how to carefully choose a cloud solution for your infrastructure, along with the factors that will help you manage your app in a cloud-based environment. Finally, you will discover software design patterns and various software approaches that will allow you to solve common problems faced during development. By the end of this book, you will be able to build and deliver highly scalable enterprise-ready apps that meet your organization’s business requirements.

Introducing Azure DevOps

Azure DevOps is a Microsoft Software-as-a-Service (SaaS) platform that enables you to deliver continuous value to your customers. By creating an account there, you will be able to easily plan your project, store your code safely, test it, publish the solution to a staging environment, and then publish the solution to the actual production infrastructure.

Of course, Azure DevOps is a complete framework and the ecosystem that it provides for software development is currently available. The automation of all the steps involved in software production ensures the continuous enhancement and improvement of an existing solution in order to adapt it to market needs.

You can start the process moving in your Azure portal. If you don't know how to create an Azure portal account, then please check Chapter 1, Understanding the Importance of Software Architecture. The steps to create an Azure DevOps account are quite simple:
