Istio: Up and Running

Preface

Who Should Read This Book

Whether as a side project, or for your core work, a service mesh is a necessary tool in your cloud native infrastructure. This book is for anyone looking to get started with Istio. It is expected that readers are comfortable with Docker and Kubernetes before starting this book, but having basic knowledge of networking and Linux should be sufficient to learn Istio through this text. Knowledge of Go or another programming language is not needed or expected.

We touch on many cloud native tools and topics such as Prometheus, Jaeger, Grafana, Meshery, Envoy, and OpenTracing. Familiarity with these is ideal, but only preliminary knowledge is sufficient to digest the contents of this book.

Why We Wrote This Book

The era of service meshes ushers in a new layer of intelligent network services that are changing the architecture of modern applications and the confidence with which they are delivered. Istio, as one of many service meshes, but one with a vast set of features and capabilities, needs an end-to-end guide.

The aim of this book is to provide that step-by-step guide to getting started with Istio. It wraps the reader’s arms all the way around it, so that their fingertips touch on the other side. Each concept is provided in a logical, organized fashion, that builds on the previously covered one. With so many moving parts and an active community, this book can’t cover all advanced use cases, but instead focuses on the core building blocks and more timeless aspects of the project. We point readers to additional resources as appropriate.

When you have worked your way through to the end of Istio: Up and Running, you should be familiar with all of Istio’s major capabilities and be able to deploy Istio in your own environments with confidence.
