Terraform is an open-source tool that helps implement IaC.
It allows you to write code in a specific language called HashiCorp Configuration Language (HCL) to describe the desired state of your infrastructure.
When you run Terraform, it reads your code and interacts with various cloud providers (like AWS, Azure, or GCP) to create or modify the resources based on your code’s instructions. Terraform automates the provisioning and management of your infrastructure, ensuring that it matches the defined state in your code.
