Terraform is an open-source Infrastructure as Code (IaC) tool developed by HashiCorp. It enables users to define and provision infrastructure resources across various cloud providers and on-premises environments using declarative configuration files.
With Terraform, users can describe their desired infrastructure configuration in a high-level configuration language called HashiCorp Configuration Language (HCL) or JSON. These configuration files define the resources, their relationships, dependencies, and configurations needed to create and manage infrastructure components, such as virtual machines, networks, storage, databases, and more.
Terraform automates the provisioning and management of infrastructure by interpreting these configuration files and applying the necessary changes to bring the actual infrastructure state in line with the desired state specified in the configuration. It supports multiple cloud providers, enabling users to manage infrastructure resources across diverse environments consistently and efficiently.
