What is the workflow for deploying new infrastructure using Terraform?

The workflow for deploying new infrastructure using Terraform follows a systematic approach to ensure that the configuration is correctly managed and applied. The correct sequence involves writing a configuration file that defines the desired state of the infrastructure. After creating the configuration, the first command to run is 'init', which initializes the working directory containing the Terraform configuration files. This step downloads any necessary provider plugins and prepares the environment for working with Terraform.

Following initialization, the 'plan' command is executed. This command allows users to preview the changes that will occur based on the current configuration compared to the existing state. It's an essential step to verify that the changes are as expected before any infrastructure alterations occur. Finally, the 'apply' command is run to actually implement the changes outlined in the plan, creating the infrastructure as specified.

This three-step process — writing a configuration, then initializing, planning, and applying — ensures that users have clear visibility into the changes being made and reduces the risk of unintended consequences during the deployment of new infrastructure.
