Terraform
Overview
What Terraform is
Terraform is HashiCorp's tool for infrastructure as code—managing servers, networks, databases, and other resources through written configuration instead of manual clicking in a console. You declare the desired end state in Terraform's configuration language, and the tool figures out the steps to reach it. The same files work across AWS, Azure, Google Cloud, and hundreds of other providers.
How it works
Terraform reads your configuration and builds a plan showing exactly what it will create, change, or destroy before anything happens. After you approve, it applies the plan and records the result in a state file that tracks real resources. Because infrastructure is defined in version-controlled code, changes are reviewable, repeatable, and easy to roll back or replicate across environments.
Why it matters
Infrastructure as code replaces fragile, undocumented manual setups with a reliable, auditable process—critical when environments must match or scale. In backend and app modernization projects, our in-house team uses Terraform to provision cloud infrastructure consistently, spin up identical staging and production environments, and pair it with Docker and Kubernetes for repeatable deployments.

FAQ
Terraform — common questions
Is Terraform free?
Terraform's core CLI is free to download and use under HashiCorp's source-available license. HashiCorp also offers paid HCP Terraform and Enterprise tiers that add remote state, collaboration, policy controls, and support. A community fork called OpenTofu remains fully open source.
Terraform vs Kubernetes?
They solve different problems. Terraform provisions infrastructure—the servers, networks, and clusters themselves. Kubernetes orchestrates containers running on that infrastructure. Many teams use Terraform to create a Kubernetes cluster, then Kubernetes to run their apps on it.
Is Terraform hard to learn?
The basics are approachable—you can provision simple resources within a day. Complexity grows with modules, state management, and multi-environment setups. Its declarative model and clear plan-before-apply workflow make it one of the more learnable infrastructure tools.
