Practical Microservices with Dapr and .NET

By: Davide Bedin

Overview of this book

Over the last decade, there has been a huge shift from heavily coded monolithic applications to finer, self-contained microservices. Dapr is a new, open source project by Microsoft that provides proven techniques and best practices for developing modern applications. It offers platform-agnostic features for running your applications on public cloud, on-premises, and even on edge devices. This book will help you get to grips with microservice architectures and how to manage application complexities with Dapr in no time. You'll understand how Dapr offers ease of implementation while allowing you to work with multiple languages and platforms. You'll also understand how Dapr's runtime, services, building blocks, and software development kits (SDKs) help you to simplify the creation of resilient and portable microservices. Dapr provides an event-driven runtime that supports the essential features you need to build microservices, including service invocation, state management, and publish/subscribe messaging. You'll explore all of those in addition to various other advanced features with this practical guide to learning Dapr. By the end of this book, you'll be able to write microservices easily using your choice of language or framework by implementing industry best practices to solve problems related to distributed systems.

Chapter 9: Tracing Dapr Applications

In this chapter, you will learn about observability options in Dapr by exploring how traces, logs, and metrics are emitted and can be collected in Dapr using Zipkin, Prometheus, and Grafana. These are the main topics of the chapter:

  • Observing applications in Dapr
  • Tracing with Zipkin
  • Analyzing metrics with Prometheus and Grafana

With Dapr in self-hosted mode, which we used during the development of our Dapr applications, we had an option to directly access the logs from the Dapr sidecar processes and applications as console output, in addition to the ability to debug our service code with Visual Studio Code (VS Code).

In the Kubernetes mode of Dapr, however, the approach is going to be different because of the complexity of a multi-node cluster and the constraints imposed on a production environment.
