Terraform (HashiCorp)

Terraform is an open-source infrastructure as code tool created by HashiCorp that enables developers and operations teams to define, provision, and manage cloud infrastructure using a declarative configuration language called HashiCorp Configuration Language (HCL). Founded in 2012 by Mitchell Hashimoto and Armon Dadgar, HashiCorp is headquartered in San Francisco, California, and Terraform has become the industry standard for infrastructure as code, used by millions of practitioners worldwide. HashiCorp has integrated AI capabilities into the Terraform ecosystem through multiple initiatives. Terraform Cloud and Terraform Enterprise now leverage AI to provide intelligent policy suggestions, configuration recommendations, and natural language explanations of infrastructure changes through integration with AI assistants. HashiCorp's AI-powered features help users generate Terraform configurations from natural language descriptions, understand complex infrastructure plans, and identify potential security and compliance issues before resources are provisioned. Terraform's core strength lies in its provider ecosystem, with over 3,000 providers that enable management of resources across virtually every major cloud platform including AWS, Azure, Google Cloud, and hundreds of SaaS services. The tool tracks infrastructure state and creates execution plans that show exactly what changes will be applied before any modifications are made, enabling safe and predictable infrastructure management. Terraform modules allow teams to create reusable infrastructure components that enforce organizational standards and best practices. Terraform Cloud provides remote state management, policy enforcement through Sentinel and OPA, run triggers, VCS integration, and team collaboration features. The core Terraform CLI is open-source under the Business Source License. Terraform Cloud offers a free tier for small teams, a Standard plan at $0.00014 per resource per hour, and a Plus plan with additional governance features. Terraform Enterprise is available for self-hosted deployment with custom pricing.
