Overview of this book

This book will guide you through various hands-on practical examples for implementing event-driven microservices architecture using C# 11 and .NET 7. It has been divided into three distinct sections, each focusing on different aspects of this implementation. The first section will cover the new features of .NET 7 that will make developing applications using EDA patterns easier, the sample application that will be used throughout the book, and how the core tenets of domain-driven design (DDD) are implemented in .NET 7. The second section will review the various components of a local environment setup, the containerization of code, testing, deployment, and the observability of microservices using an EDA approach. The third section will guide you through the need for scalability and service resilience within the application, along with implementation details related to elastic and autoscale components. You’ll also cover how proper telemetry helps to automatically drive scaling events. In addition, the topic of observability is revisited using examples of service discovery and microservice inventories. By the end of this book, you’ll be able to identify and catalog domains, events, and bounded contexts to be used for the design and development of a resilient microservices architecture.

Sharing API services

So far, in our example TAEDA application, we have focused on various domain information that is closely interrelated. As a lone developer, you can probably recall most of the API endpoints you created in one microservice when you come to utilize them in another microservice. However, in practice, we don’t develop in isolation. One of the key benefits of microservice architecture is the ability to divide and conquer by assigning smaller domains to different teams (or lone developers). In fact, we don’t want to limit the understanding of our APIs to just the teams associated with the main solution, but to any other teams that might be able to benefit from these same services.

Let’s imagine a scenario where there is an intent to conduct a study on transit foot traffic patterns and how they correlate with major sporting events around various cities. We already have many services designed to support the backbone of the transit management system...
