     - `main.tf`: will contain the main set of configurations for your project. Here, it will be our Instance

     - `backend.tf`: each Terraform configuration can specify a backend, which defines where the state file of the current infrastructure will be stored. Terraform uses this file to keep track of the managed resources. This state can be stored locally or remotely. Configuring a remote backend allows multiple people to work on the same infrastructure
     - `variables.tf`: will contain the variable definitions for your project. Since all Terraform values must be defined, any variables that are not given a default value will become required arguments
     - `terraform.tfvars`: allows you to set the actual value of the variables
