Do all standard backend types support state storage, locking, and remote operations?

The correct understanding is that only some standard backend types in Terraform support state storage, locking, and remote operations. For instance, remote backends such as the S3 backend (with DynamoDB for locking) or the Terraform Cloud backend do indeed provide state storage and implement locking mechanisms, allowing for enhanced collaboration and preventing race conditions during Terraform operations.

However, other backend types, especially the local backend, do not support these features. The local backend stores state information on the local filesystem and does not implement state locking, making it susceptible to issues that can arise when multiple users or systems attempt to work with the same state file simultaneously.

Understanding the various backend types and their capabilities is crucial, as it informs the optimal infrastructure setup for Terraform projects, especially in collaborative environments where multiple team members might be making changes to the same infrastructure.
