Preface

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, containerization of code, testing, deployment, and 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.

You’ll also learn the tenets of event-driven architecture, coupled with reliable design patterns to enhance your knowledge of distributed systems and build a foundation for professional growth. You’ll also understand how to translate business goals and drivers into a domain model that can be used to develop an app that enables those goals and drivers, and identify areas to enhance development and ensure operational support through the architectural design process.

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.
