Modern DevOps Practices

By: Gaurav Agarwal

Overview of this book

Containers have entirely changed how developers and end-users see applications as a whole. With this book, you'll learn all about containers, their architecture and benefits, and how to implement them within your development lifecycle. You'll discover how you can transition from the traditional world of virtual machines and adopt modern ways of using DevOps to ship a package of software continuously. Starting with a quick refresher on the core concepts of containers, you'll move on to study the architectural concepts to implement modern ways of application development. You'll cover topics around Docker, Kubernetes, Ansible, Terraform, Packer, and other similar tools that will help you to build a base. As you advance, the book covers the core elements of cloud integration (AWS ECS, GKE, and other CaaS services), continuous integration, and continuous delivery (GitHub actions, Jenkins, and Spinnaker) to help you understand the essence of container management and delivery. The later sections of the book will take you through container pipeline security and GitOps (Flux CD and Terraform). By the end of this DevOps book, you'll have learned best practices for automating your development lifecycle and making the most of containers, infrastructure automation, and CaaS, and be ready to develop applications using modern tools and techniques.

The need for serverless offerings

So far, we've been spinning up and down compute instances such as virtual machines. Somehow, we were aware of and optimized the number of resources, machines, and all the infrastructure surrounding the applications we'd built. Still, you want your team to focus on what they do best – code development. Unless your organization wants to invest heavily in an expensive infrastructure team to do a lot of heavy lifting behind the scenes, you'd be better off concentrating on writing and building quality applications, rather than focusing on where and how to run them and how to optimize them.

Serverless offerings come as a reprieve for this problem. Instead of concentrating on how to host your infrastructure to run your applications, you can declare what you want to run, and the serverless offering manages it for you. This has come as a boon for small enterprises that do not have the budget to invest heavily in infrastructure and want...
