What is Terraform?

Terraform is an open-source infrastructure as code (IaC) tool created by HashiCorp. It allows developers to define and provide data center infrastructure using a declarative configuration language. By using this tool, you can manage service providers as well as in-house custom solutions.

Key Features of Terraform

Infrastructure as Code

With Terraform, you can write declarative configuration files. This practice allows versioning and reusability, thus reducing potential human errors while deploying and managing infrastructure.

Execution Plans

Terraform generates an execution plan describing what it will do to achieve the desired state. This makes it easier for you to understand the actions Terraform will perform prior to any changes being made.

Resource Graph

Terraform builds a graph of all your resources. This helps Terraform understand the dependencies between your resources and parallelize the creation and modification of any non-dependent resources, thus increasing efficiency.

Why Use Terraform?

As a website designer, developer or administrator, you may find yourself dealing with various components of the infrastructure. Terraform enables you to manage a broad spectrum of services such as IaaS, PaaS, and SaaS. Here are a few reasons why you should consider using Terraform:

  • It’s provider agnostic: You can use it with any cloud service provider.
  • It’s easy to understand and use: The HashiCorp Configuration Language (HCL) is both human and machine-friendly.
  • It’s highly efficient: Terraform’s ability to build resource graphs and execute non-dependent tasks in parallel speeds up infrastructure deployment.
  • It’s safe: Terraform’s execution plan and resource graph features provide predictability and visibility into changes.


In conclusion, Terraform is a powerful tool that can help you manage your infrastructure more efficiently and safely. Its features such as infrastructure as code, execution plans and resource graph make it a go-to for many developers. Whether you’re working with a single cloud service provider or a hybrid model, Terraform can simplify your infrastructure management tasks.
