You must have heard of IaaS, Paas and SaaS. There is something called IaC or IaaC which stands for Infrastructure as a Code. Terraform is a popular infrastructure-as-code (IaC) tool that enables the automation provisioning and management of infrastructure resources. It generally uses configuration files which are written in the HashiCorp Configuration Language (HCL) to define the required uses of your infrastructure.
It uses numerous commands to apply the configurations and manage infrastructure resources. Terraform is developed and managed by the HashiCorp software company.
