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.

Technical requirements

The technical requirements in this chapter are similar to Chapter 4. We will be using AWS EKS to deploy a website for an online boutique store, which is an open source application available under Apache License 2.0 at https://github.com/GoogleCloudPlatform/microservices-demo.

Please check Chapter 4’s Technical requirements section to set up the infrastructure in AWS using Terraform, set up kubectl, and install Istio including observability add-ons. To deploy the Online Boutique store application, please use the deployment artifacts in the Chapter12/online-boutique-orig file on GitHub.

You can deploy the Online Boutique store application using the following commands:

$ kubectl apply -f Chapter12/online-boutique-orig/00-online-boutique-shop-ns.yaml
namespace/online-boutique created
$ kubectl apply -f Chapter12/online-boutique-orig

The last command should deploy the Online Boutique application. After some time, you should be able to see all the...
