Bootstrapping Service Mesh Implementations with Istio

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.

Technical requirements

In this section, we will create an AWS cloud setup, which will be used to perform hands-on exercises in this and subsequent chapters. You can use any cloud provider of your choice, but to introduce some variety in this book, I have selected AWS for Part 2 and Google Cloud for Part 3. You can also use minikube for the exercises, but you will need at least a quad-core processor and 16 GB or more of RAM assigned to minikube for smooth, lag-free operations.

Setting up the environment

Let’s go!

  1. Create an AWS account. If you don’t already have an AWS account, then it’s time to sign up with AWS using https://portal.aws.amazon.com/billing/signup#/start/email.
  2. Set up the AWS CLI:
    1. Install the AWS CLI using the steps provided at https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html.
    2. Configure the AWS CLI using the steps provided at https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html.
  3. Install...
