Terraform has become a key player in the DevOps world for defining, launching, and managing infrastructure as code (IaC) across a variety of cloud and virtualization platforms, including AWS, Google Cloud, Azure, and more. This hands-on third edition, expanded and thoroughly updated for version 1.0 and beyond, shows you the fastest way to get up and running with Terraform.

Gruntwork cofounder Yevgeniy (Jim) Brikman takes you through code examples that demonstrate Terraform's simple, declarative programming language for deploying and managing infrastructure with a few commands. Veteran sysadmins, DevOps engineers, and novice developers will quickly go from Terraform basics to running a full stack that can support a massive amount of traffic and a large team of developers.

Compare Terraform with Chef, Puppet, Ansible, CloudFormation, and Pulumi
Deploy servers, load balancers, and databases
Create reusable infrastructure with Terraform modules
Test your Terraform modules with static analysis, unit tests, and integration tests
Configure CI/CD pipelines for both your apps and infrastructure code
Use advanced Terraform syntax for loops, conditionals, and zero-downtime deployment
Get up to speed on Terraform 0.13 to 1.0 and beyond
Work with multiple clouds and providers (including Kubernetes!)
