Istio in Action

Solve difficult service-to-service communication challenges around security, observability, routing, and resilience with an Istio-based service mesh. Istio allows you to define these traffic policies as configuration and enforce them consistently without needing any service-code changes.

In Istio in Action you will learn:

Why and when to use a service mesh
Envoys role in Istios service mesh
Allowing North-South traffic into a mesh
Fine-grained traffic routing
Make your services robust to network failures
Gain observability over your system with telemetry golden signals
How Istio makes your services secure by default
Integrate cloud-native applications with legacy workloads such as in VMs

Reduce the operational complexity of your microservices with an Istio-powered service mesh! Istio in Action shows you how to implement this powerful new architecture and move your application-networking concerns to a dedicated infrastructure layer. Non-functional concerns stay separate from your application, so your code is easier to understand, maintain, and adapt regardless of programming language. In this practical guide, youll go hands-on with the full-featured Istio service mesh to manage microservices communication. Helpful diagrams, example configuration, and examples make it easy to understand how to control routing, secure container applications, and monitor network traffic.

Foreword by Eric Brewer.

About the technology
Offload complex microservice communication layer challenges to Istio! The industry-standard Istio service mesh radically simplifies security, routing, observability, and other service-to-service communication challenges. With Istio, you use a straightforward declarative configuration style to establish application-level network policies. By separating communication from business logic, your services are easier to write, maintain, and modify.

About the book
Istio in Action teaches you how to implement an Istio-based service mesh that can handle complex routing scenarios, traffic encryption, authorization, and other common network-related tasks. Youll start by defining a basic service mesh and exploring the data plane with Istios service proxy, Envoy. Then, youll dive into core topics like traffic routing and visualization and service-to-service authentication, as you expand your service mesh to workloads on multiple clusters and legacy VMs.

What\'s inside

Comprehensive coverage of Istio resources
Practical examples to showcase service mesh capabilities
Implementation of multi-cluster service meshes
How to extend Istio with WebAssembly
Traffic routing and observability

Review

"Presents a clear-headed vision of how to achieve the goal of decoupling applications from infrastructure. I hope you'll enjoy this book as much as I have."
From the Foreword by Eric Brewer, VP Infrastructure and Google Fellow

"I really enjoyed the gentle introduction to Istio. I can easily recommend this book to everyone starting development with Kubernetes."
Christoph Schubert, SAP SE

"A comprehensive guide for building an in-depth understanding of the Istio service mesh."
Fotis Stamatelopoulos, Upwork

"It felt like I was shadowing a highly skilled subject matter expert."
Paolo Antinori, Red Hat

From the Author

Rinor (@rinormaloku) and I (@christianposta) have worked over the past 5+ years with users of the Istio community and customers of Solo.io adopting Istio and service mesh in production. This book represents the hard-learned experiences of using Istio in real environments and has something for all: beginner, intermediate, and advanced users of Istio. We cover basics of service mesh, how it enables safer/faster deployments by abstracting common application networking patterns into a sidecar. We also discuss security, metric collection, VM, multi-cluster and extensibility use cases with Istio and Envoy proxy.
