Modern DevOps Practices

Enhance DevOps workflows by integrating the functionalities of Git, Docker, Kubernetes, Argo CD, Ansible, Terraform, Istio, and more with the help of practical examples and expert tips

Key Features

• Explore containers as a service (CaaS) and infrastructure automation in the public cloud
• Secure and ship software continuously to production with DevOps, GitOps, SecOps, and automation
• Operate distributed and scalable microservices apps in the cloud with a modern service mesh

Book Description

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.

By the end of this DevOps book, you’ll be well-equipped to develop and operate applications using modern tools and techniques.
