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.

Resiliency through cloud-native patterns

Application resiliency can be measured by how durable and recovery prone a service or application is. There are different paradigms for analyzing and implementing resiliency in applications, including infrastructure and software design patterns. For the purposes of this chapter, we will be examining software patterns that leverage cloud-first architectural patterns to bolster application resiliency.

While we can review the architectural patterns using the Azure architecture center as well as various sources for software resiliency, we’re going to be looking at a library that’s fairly prevalent, especially in cloud-first development circles. This library is called Polly.net. Polly.net is a library that allows you to implement several different types of policies in either a synchronous or asynchronous manner to address specific issues or to combat known problems with cloud service transiency, as well as advanced error handling...
