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.

Chapter 9: Containers as a Service (CaaS) and Serverless Computing for Containers

In the last three chapters, we have covered immutable infrastructure, configuration as code, and infrastructure as code and how to use Packer, Ansible, and Terraform to create one. These chapters introduced you to the era of modern DevOps, where everything is automated. We follow the same principles for building and deploying all kinds of infrastructure, be it containers or virtual machines.

Now, let's get back to the container world and look at other ways of automating and managing container deployments – Containers as a Service (CaaS) and Serverless computing for containers. CaaS provides container-based virtualization that abstracts away all management behind the scenes and helps you manage your containers, without worrying about the underlying infrastructure and orchestration. For simple deployments and less complex applications, CaaS can be a savior. Serverless computing is a broad...
