By: Gaurav Agarwal

Overview of this book

DevOps and the cloud have changed how we look at software development and operations like never before, leading to the rapid growth of various DevOps tools, techniques, and practices. This updated edition helps you pick up the right tools by providing you with everything you need to get started with your DevOps journey. The book begins by introducing you to modern cloud-native architecture, and then teaches you about the architectural concepts needed to implement the modern way of application development. The next set of chapters helps you get familiarized with Git, Docker, Kubernetes, Ansible, Terraform, Packer, and other similar tools to enable you to build a base. As you advance, you’ll explore the core elements of cloud integration—AWS ECS, GKE, and other CaaS services. The chapters also discuss GitOps, continuous integration, and continuous delivery—GitHub actions, Jenkins, and Argo CD—to help you understand the essence of modern app delivery. Later, you’ll operate your container app in production using a service mesh and apply AI in DevOps. Throughout the book, you’ll discover best practices for automating and managing your development lifecycle, infrastructure, containers, and more.

Introduction to service mesh

Imagine being in a bustling city with a complex network of roads and highways. You’re driving your car from one side of the city to the other. In this scenario, you deal with the following entities:

  • Your car: Your car represents an individual service or application in a computer system. It has a specific purpose, just like a microservice or application in a software architecture.
  • Roads and highways: The roads and highways are like the network connections and communication pathways between different services in your application. Services need to interact and communicate with each other to perform various functions, just as vehicles need roads to get from one place to another.
  • Traffic lights and signs: Traffic lights, signs, and road rules help manage traffic flow, ensuring that vehicles (services) can safely and efficiently navigate the city. These are like the rules, protocols, and tools in a service mesh regulating communication...
