Mastering Service Mesh

By: Anjali Khatri, Vikram Khatri

Overview of this book

Although microservices-based applications support DevOps and continuous delivery, they can also add to the complexity of testing and observability. The implementation of a service mesh architecture, however, allows you to secure, manage, and scale your microservices more efficiently. With the help of practical examples, this book demonstrates how to install, configure, and deploy an efficient service mesh for microservices in a Kubernetes environment. You'll get started with a hands-on introduction to the concepts of cloud-native application management and service mesh architecture, before learning how to build your own Kubernetes environment. While exploring later chapters, you'll get to grips with the three major service mesh providers: Istio, Linkerd, and Consul. You'll be able to identify their specific functionalities, from traffic management, security, and certificate authority through to sidecar injections and observability. By the end of this book, you will have developed the skills you need to effectively manage modern microservices-based applications.

Technical requirements

To complete the exercises in this chapter, you will require the following equipment:

  • A macOS or Windows computer with the following configuration:
    • For Windows: A minimum of 16 GB of RAM and an Intel Core i7 or higher processor with a minimum of 4 CPU cores
    • For macOS: A macOS Pro (2015) onwards with 16 GB of RAM, Intel Core i7 processor, with 4 cores, and preferably 512 GB SSD (minimum)
  • A virtualization software to build a VM.
As you go to through the book and example commands or script, pay attention to the commands that you need to run as root or as a user.

The username in the VM is user. The root and user passwords have been set to password for ease of memory. If the command uses # as a prefix, you should run it as root. Commands prefixed with $ need to be run as a regular user and not as root. We show the usage of sudo wherever it is required to...
