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.

Installing Istio

This section is the one you must have been eagerly waiting to read. The wait is over, and you are all set to install Istio. Just follow the instructions provided.

The first step is to download Istio from https://github.com/istio/istio/releases. You can download using curl as well with the following command. It is a good idea to make a directory where you want to download the binaries and run the following command from within that directory. Let’s name that directory ISTIO_DOWNLOAD, from which we can run following commands:

$ curl -L https://istio.io/downloadIstio | sh -
Downloading istio-1.13.1 from https://github.com/istio/istio/releases/download/1.13.1/istio-1.13.1-osx.tar.gz ...
Istio 1.13.1 Download Complete!

The preceding command downloads the latest version of Istio into the ISTIO_DOWNLOAD location. If we dissect this command, it has two parts:

$ curl -L https://istio.io/downloadIstio

The first part of the command downloads a script from...
