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.

Implementing fault injection and chaos tests

Suites such as Gremlin aim to make the adoption of chaos engineering easier to move toward since the Chaos Monkey suite popularized by Netflix can have an aggressive learning curve. For Kubernetes-based applications, a popular framework for chaos testing is Chaos Mesh. While it has not been around as long as suites such as Chaos Monkey, Chaos Mesh is a solid choice for implementing chaos experiments in a uniform way against a modular orchestration engine. Chaos Mesh is also an incubating project with the Cloud Native Computing Foundation (CNCF), which exposes it to a larger open source community for use.

It’s interesting to note that Azure Chaos Studio, which we will be using to set up some baseline experiments, relies on Chaos Mesh behind the scenes to orchestrate and run experiments against Kubernetes-based targets. It also allows for agent-based installations on virtual machines, as well as virtual machine scale sets and other...
