Terraform tool can be used to build, change, and versioning infrastructure in a safe and efficient way. Terraform is built on a plugin-based architecture, helping developers to extend Terraform by writing new plugins or compiling modified versions of existing plugins.
Terraform is logically split into two parts such as Terraform Core and Terraform Plugins. Terraform Core uses remote procedure calls to communicate with Terraform Plugins and provides many ways to discover and load plugins to use. Terraform Plugins expose an implementation for a specific service, such as AWS, or provisioner, such as bash.
