Concepts
Self-built Bucket
Self-built buckets are those created by the current user, including public buckets and private buckets.
Public Bucket
If you set Bucket Policy to Public Read or Public Write when creating an OBS bucket, the bucket is a public bucket. Any user can read, write, or delete objects in the bucket.
Private Bucket
If you set Bucket Policy to Private when creating an OBS bucket, the bucket is a private bucket and only the current user can access it.
Other Buckets
Other buckets refer to the buckets that are created by other users and assigned the Public policy or the private buckets on which the current account has permissions.
