Modern DevOps Practices

The Modern Way of DevOps

This first chapter will provide some background knowledge of DevOps practices, processes, and tools. We will understand modern DevOps and how it differs from traditional DevOps. We will also introduce containers and understand in detail how containers within the cloud change the entire IT landscape so that we can build on this book’s base. While this book does not entirely focus on containers and their orchestration, modern DevOps practices heavily emphasize it.

In this chapter, we’re going to cover the following main topics:

  • What is DevOps?
  • Introduction to cloud computing
  • Understanding modern cloud-native applications
  • Modern DevOps versus traditional DevOps
  • The need for containers
  • Container architecture
  • Containers and modern DevOps practices
  • Migrating to containers from virtual machines

By the end of this chapter, you should understand the following key aspects:

  • What DevOps is and what role it plays in the modern IT landscape
  • What cloud computing is and how it has changed IT services
  • What a modern cloud-native application looks like and how it has changed DevOps
  • Why we need containers and what problems they solve
  • The container architecture and how it works
  • How containers contribute to modern DevOps practices
  • The high-level steps of moving from a virtual machine-based architecture to containers

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.

Who is this book for?

If you are a software engineer, system administrator, or operations engineer looking to step into the world of DevOps within public cloud platforms, this book is for you. Existing DevOps engineers will also find this book helpful as it covers best practices, tips, and tricks for implementing DevOps with a cloud-native mindset. Although no containerization experience is necessary, a basic understanding of the software development life cycle and delivery will help you get the most out of this book.

The book lives up to its promise of providing the readers with everything that they would need to begin their career as a DevOps Engineer. It has an extremely well-set flow, and the author not only provides knowledge of core concepts and tools associated with them, but the practical nature of the book allows the readers to have a more hands-on experience, making the learning more enjoyable. It covers almost all topics that you would want to learn to practice DevOps within your organization. The best part of the book is the example Blog App that the author uses to explain the concepts. It feels like you are building an Application and then using DevOps around it to Build, Test, Deliver, Secure, and Operate it effectively using cutting-edge tools.

It’s been a while since I read a technical book cover-to-cover, so I was delighted to reach the end. In around 550 pages, the book systematically covers many DevOps and related topics, everything from Amazon ECS to ZFS and the bewildering number of technologies and acronyms that seem to prevail the IT landscape at present. Though fasten your seatbelts, it’s a high-octane ride.The book houses five major sections: a) DevOps Fundamentals b) Container Orchestration c) Managing Config & Infrastructure d) Delivery with GitOps e) Production OperationThe practical exercises add haldi (turmeric) and jira (yes, intended- cumin) to the work, making the subject all together less esoteric and approachable. I was particularly pleased to see Gaurav continue the ‘Hello World’ tradition (my first Hello World was written in Pascal, 1993).Gaurav peppers the theory with useful, real-world tips, a testament to his knowledge, experience, and genuine zeal in this area.Each chapter ends with a list of questions to reader has been paying attention (though I’d prefer the answers at the end of the book, to stop a roving eye). The extra chapter explaining the role of AI in DevOps is a welcome, topical addition, something I’m sure that will take a more prominent position in future editions. Perhaps a slight variant, Modern DevOps (Light) could present a condensed ‘management friendly’ treatment along with additional chapters on cost/management implications of DevOps.In any case, the book is very well written and presented, though the heading capitalisation style took a little while to adjust. The free PDF version is also a generous touch.In short, a weighty, practical tome on all matters DevOps, worthy of a few inches on any techie’s bookshelf.Now I have more ‘free’ subscriptions than I thought possible, but I’m looking forward to bombarding the team with new acronyms and asking why we’re not using Grype and Jinja2 templates.

After having read the first edition, the second edition is a great improvement over the first. Though this edition still guides readers through Cloud, DevOps, containers and the essential considerations for integrating it into their systems, the approach that it takes through the example Blog Application is even more helpful. The author explores CI/CD pipelines through the lens of GitOps which makes it even more cloud native, while offering a well-structured journey from foundational concepts to advanced insights, accompanied by helpful visuals and terminal outputs. Suitable for both beginners and those with basic knowledge, it serves as an excellent resource for mastering containers, Docker, Kubernetes, and the broader realms of continuous integration, delivery, and DevOps. I highly recommend this well-crafted and instructive book for anyone embarking on the DevOps journey.
