**Source:** User input

## Documentation

*   **Description**: https://docs.s3.msk-1.ngcloud.ru/s3/s3.description.html

## Key Concepts

*   **S3 Instance (Account/User)**: This is the service level entity. It represents the S3 account/user credentials (access_key, secret_key). 
    *   *Usage*: PostgreSQL dependencies refer to this **S3 Instance**, NOT a specific bucket.
    *   Examples of UIDs: `xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`.
*   **S3 Bucket**: A container for objects within an S3 Instance.
