Remote backends, state locking, import, and state manipulation — manage Terraform state safely.
Five passes over the same idea, each from a different angle. Do them in order, or jump to whichever you need.
Terraform state maps real infrastructure to configuration. Key topics: remote backends (Azure Storage, S3, Terraform Cloud), state locking, state import for existing resources, state move/remove, and sensitive data in state. State management is critical for team collaboration and disaster recovery.
