Terraform in Action

Use Terraform to programmatically create, test, and manage infrastructure using the efficient infrastructure-as-code approach.

Summary

• In Terraform in Action you will learn:
• Cloud architecture with Terraform
• Terraform module sharing and the private module registry
• Terraform security in a multitenant environment
• Strategies for performing blue/green deployments
• Refactoring for code maintenance and reusability
• Running Terraform at scale
• Creating your own Terraform provider
• Using Terraform as a continuous development/continuous delivery platform

Terraform in Action introduces the infrastructure-as-code (IaC) model that lets you instantaneously create new components and respond efficiently to changes in demand. You’ll use the Terraform automation tool to design and manage servers that can be provisioned, shared, changed, tested, and deployed with a single command.

About the technology

Provision, deploy, scale, and clone your entire stack to the cloud at the touch of a button. In Terraform, you create a collection of simple declarative scripts that define and manage application infrastructure. This powerful infrastructure-as-code approach automates key tasks like versioning and testing for everything from low-level networking to cloud services.

About the book

Terraform in Action shows you how to automate and scale infrastructure programmatically using the Terraform toolkit. Using practical, relevant examples, you’ll use Terraform to provision a Kubernetes cluster, deploy a multiplayer game, and configure other hands-on projects. As you progress to advanced techniques like zero-downtime deployments, you’ll discover how to think in Terraform rather than just copying and pasting scripts.
