Which command allows you to see anytime your infrastructure will change?

The command that allows you to see anytime your infrastructure will change is 'terraform plan'. This command is essential in the Terraform workflow as it generates an execution plan, showing what actions Terraform will take to change the current infrastructure to match the desired configuration specified in the Terraform files.

When you run 'terraform plan', Terraform compares the current state of your infrastructure against the configurations defined in your .tf files. It will output the changes it intends to make, including additions, modifications, and deletions, without actually applying them. This allows you to review the changes beforehand, ensuring that you understand the impact of the adjustments you are about to make. This step is crucial for preventing unintended disruptions or resource modifications when managing infrastructure as code.

Other commands serve different purposes: 'terraform status' is not a valid command in Terraform, while 'terraform change' does not exist either. 'terraform up' is not used in Terraform; typically, 'terraform apply' is the command that applies the changes described in your configuration. Thus, the ability to preview changes before applying them makes 'terraform plan' the clear choice for understanding how your infrastructure will change.
