专家怎么看待这一现象？

多位业内专家指出，Authorization is equally thorny. S3 and file systems think about authorization in very different ways. S3 supports IAM policies scoped to key prefixes—you can say “deny GetObject on anything under /private/”. In fact, you can further constrain those permissions based on things like the network or properties of the request itself. IAM policies are incredibly rich, and also much more expensive to evaluate than file permissions are. File systems have spent years getting things like permission checks off of the data path, often evaluating up front and then using a handle for persistent future access. Files are also a little weird as an entity to wrap authorization policy around, because permissions for a file live in its inode. Hard links allow you to have many inodes for the same file, and you also need to think about directory permissions that determine if you can get to a file in the first place. Unless you have a handle on it, in which case it kind of doesn’t matter, even if it’s renamed, moved, and often even deleted.
