Explain the benefits of state

Terraform must store state about your managed infrastructure and configuration. This state is used by Terraform to map real world resources to your configuration, keep track of metadata, and to improve performance for large infrastructures.

Is stored by default in a local file named terraform.tfstate.

• terraform import
• terraform state rm

Purpose

• Mapping the Real World
