Terraform – IaC
Terraform is a vendor-neutral tool and library for deploying and managing infrastructure. Terraform is written in the Hashicorp language, which is a high-level declarative language. The one key component that makes Terraform work is the state file. The state file is basically a transaction log for your resources. The transaction log is the way Terraform knows what to build, modify, and delete. If you lose your state file, you will have to manually manage the infrastructure that was created.
It is also possible to create small reusable modules of Terraform code and break up your state files into smaller units. In cases where you break your state file up, you can define other state files to use in your configuration file.
