The definitive guide to understand Istio and when it's worth using it.

Andrea Cosentino
Look inside
Many enterprise applications intertwine code that defines an app’s behavior with code that defines its network communication and other non-functional concerns. The “service mesh” pattern, implemented by platforms like Istio, helps you push operational issues into the infrastructure so the application code is easier to understand, maintain, and adapt. Istio in Action teaches you how to implement a full-featured Istio-based service mesh to manage a microservices application. With the skills you learn in this comprehensive tutorial, you’ll be able to delegate the complex infrastructure of your cloud-native applications to Istio!

about the technology

Cloud-native applications can include thousands of clustered containers, distributed components, and complex interactions. To build them effectively, developers need a new approach to infrastructural concerns like monitoring, storage, scaling, orchestration, and security. The Istio platform offers a configurable infrastructure layer called a service mesh that reliably and efficiently manages day-to-day concerns like service discovery, load balancing, encryption, authentication and authorization, circuit breakers, and more. Open source and cloud-ready, Istio is a welcome upgrade from manually managed microservices infrastructure.

about the book

Istio in Action is a comprehensive guide to handling authentication, routing, retrying, load balancing, collecting data, security, and other common network-related tasks using the Istio service mesh platform. With author Christian Posta’s expert guidance, you’ll experiment with a basic service mesh as you explore the features of Envoy, Istio’s service proxy. With helpful diagrams and hands-on examples, you’ll learn how to use this open-source service mesh to control routing, secure container applications, and monitor network traffic. You’ll also bring Istio to legacy systems without changes to your applications and discover how to use Istio in a multi-cloud world with the data layer deployed on a cluster like Kubernetes.

Michael J. Haller

The perfect blend of how and why.

Morgan Nelson

Istio: how to use it, when to use it, what it is, and most importantly, what it is not.

Andrea Tarocchi

Provides detailed information on an exciting technology with a ton of real-world examples. The authors walk readers through a difficult subject with ease. Highly recommended.

Morgan Nelson

A thorough treatment of Istio with excellent examples you can reproduce. I learnt a lot about Service Mesh, its "raison d'etre", and Istio's capabilities. Excellent resource!
