What is a cloud storage architecture that manages the data in a hierarchy of files?

Object-based storage manages data as flat objects with unique identifiers and metadata, not in a hierarchy.

File-based storage, often implemented via Network File System (NFS) or Server Message Block (SMB) protocols, presents data to users and applications in a traditional hierarchical directory structure with files and folders, similar to a local file system. This allows for familiar file-level operations and access controls.

A database is a structured collection of data, typically accessed and managed through a database management system, not primarily a file hierarchy.

A Content Delivery Network (CDN) is a distributed network of servers that delivers cached web content to users based on geographic location, not a primary storage architecture.
