Terraform
Write, Plan, and Create Infrastructure as Code
About Terraform
Terraform enables you to safely and predictably create, change, and improve infrastructure.
HashiCorp Terraform enables you to safely and predictably create, change, and improve infrastructure. It is an open source tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.
- SIMPLE AND POWERFUL
- INFRASTRUCTURE AS CODE
- ONE SAFE WORKFLOW ACROSS PROVIDERS
