Terraform

In simple English

Terraform enables engineers to write infrastructure configuration in HCL (HashiCorp Configuration Language) and apply it to cloud providers like AWS, Azure, Google Cloud, and others. Instead of manually creating resources through web consoles, teams use Terraform files to version control, review, and automate infrastructure changes. This approach makes deployments reproducible, auditable, and scalable across multiple environments. In real tech companies, Terraform is central to DevOps workflows. Teams use it to manage databases, networks, compute instances, and storage with version control. For example, a startup might version their entire production infrastructure in Git, allowing any team member to review infrastructure changes before deployment. It reduces human error, enables infrastructure review processes similar to code review, and makes disaster recovery and environment scaling straightforward. Terraform also maintains state files that track what resources currently exist. This allows teams to plan changes before applying them, ensuring you know exactly what will be created, modified, or destroyed. When someone mentions Terraform at work, they typically mean either the tool itself, the configuration files, or the process of using Terraform to manage infrastructure.

Say it like this

✓We Terraform our entire infrastructure
✓Let us apply Terraform to staging first
✓This needs to be managed by Terraform, not manually

Real examples

in a standup

"I finished the Terraform configuration for the new RDS instance and opened a PR for review."

in a code review

"Before we merge this Terraform code, we need to run terraform plan to see what resources will be created."

in a team meeting

"Moving to Terraform will help us avoid manual infrastructure changes and keep everything in version control."

Don't say this

Handle with care. Terraform is a proper noun referring to the HashiCorp tool. Do not confuse it with the general concept of reshaping land or use it as a generic verb for infrastructure provisioning.

✕We are going to terraform the whole system.
✓We are going to use Terraform to provision the entire system.— Terraform is a product name, not a verb meaning to change something broadly. Be specific that you are using the tool.
✕Terraform is just like CloudFormation, they are the same thing.
✓Terraform and CloudFormation are both Infrastructure as Code tools, but Terraform is cloud-agnostic while CloudFormation is AWS-specific.— While similar, they are different tools with different capabilities and vendor lock-in implications.
✕I will terraform this server manually.
✓I will write a Terraform configuration for this server.— Terraform is declarative infrastructure automation, not manual provisioning.
