Cloud file storage provides shared file systems in the cloud. It is useful when multiple servers, applications, or users need access to the same folder-style storage.
Where file storage fits
File storage can support content management, shared application files, home directories, analytics workloads, and lift-and-shift migrations where applications expect a shared file system.
How it differs from object storage
Object storage is usually accessed through APIs and stores objects. File storage behaves more like a traditional network file share.
Cloud file storage is helpful when the application wants files, folders, and shared paths.
