By: Anand Rai

Overview of this book

Istio is a game-changer in managing connectivity and operational efficiency of microservices, but implementing and using it in applications can be challenging. This book will help you overcome these challenges and gain insights into Istio's features and functionality layer by layer with the help of easy-to-follow examples. It will let you focus on implementing and deploying Istio on the cloud and in production environments instead of dealing with the complexity of demo apps.  You'll learn the installation, architecture, and components of Istio Service Mesh, perform multi-cluster installation, and integrate legacy workloads deployed on virtual machines. As you advance, you'll understand how to secure microservices from threats, perform multi-cluster deployments on Kubernetes, use load balancing, monitor application traffic, implement service discovery and management, and much more. You’ll also explore other Service Mesh technologies such as Linkerd, Consul, Kuma, and Gloo Mesh. In addition to observing and operating Istio using Kiali, Prometheus, Grafana and Jaeger, you'll perform zero-trust security and reliable communication between distributed applications. After reading this book, you'll be equipped with the practical knowledge and skills needed to use and operate Istio effectively.

Exploring alternatives to Istio

There are various other alternatives to Istio, all with their own pros and cons. Here, we will list a few of the other Service Mesh implementations available.


At the time of writing (2022), Kuma is a Cloud Native Computing Foundation (CNCF) sandbox project and was originally created by Kong Inc., the company that also provides the Kong API management gateway both in open source and commercial variants. Kuma is advertised by Kong Inc. as a modern distributed control plane with bundled Envoy proxy integration. It supports multi-cloud and multi-zone connectivity for highly distributed applications. The Kuma data plane is composed of Envoy proxies, which are then managed by Kuma control planes, and it supports workloads deployed on not only Kubernetes but also virtual machines and bare-metal environments. Kong Inc also provides an enterprise Service Mesh offering called Kong Mesh, which extends CNCF’s Kuma and Envoy.
