Explanation of tfstate File

The Terraform state file (terraform.tfstate) is a crucial part of Terraform. It is used to map real-world resources to your configuration, keep track of metadata, and improve performance for large infrastructures.

Key Points about tfstate:

• Resource Mapping: Tracks resources Terraform manages.
• Metadata Storage: Stores necessary information for managing infrastructure.
• Performance: Enhances performance for large infrastructures by caching resource attributes.
• Sensitive Data: May contain sensitive data, so it should be stored securely.
