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.

Using SOLID principles to map your domains

In the following subsections, we will describe some of the patterns that are commonly used with DDD. Some of them can be adopted in all projects, while others can only be used for certain Bounded Contexts. The general idea is that the business layer is split into two layers:

  • Application layer
  • Domain layer

Here, the domain layer is an abstraction of the data layer based on the Ubiquitous Language. It is where DDD entities and value objects are defined together with abstractions of the operations to retrieve and save them. These operations are defined in interfaces that are implemented in the underlying data layer (Entity Framework in our case).

The application layer, instead, defines operations that use the domain layer interfaces, to get DDD entities and value objects, and that manipulate them to implement the application business logic.

As we will see later on in this chapter, it is common to implement the...
