Do I need shared file storage for my application or can I just use object storage?

It depends on how your application uses files.
Use object storage if you:
- Store uploads, images, videos, logs, backups, or documents
- Don’t need true filesystem behavior
- Can access files via an API/URL instead of a mounted drive
- Want easy scaling and durability
Object storage examples: S3, GCS, Azure Blob, MinIO
Object storage is usually the best default for:
- User uploads
- Static assets
- Media processing pipelines
- Backups and archives
Use shared file storage if you need:
- A real filesystem mounted by multiple servers
- File locking or atomic rename semantics
- Applications that expect POSIX-style behavior
- Shared read/write access to the same directory from multiple instances
- Legacy software that can’t be changed easily
Shared file storage examples: NFS, EFS, Azure Files, Filestore
Quick rule of thumb
Choose object storage unless your app specifically needs:
chmod,rename, symlinks, directory traversal semantics- low-latency shared filesystem access
- multiple processes/servers reading and writing the same files as a mounted path
Common architecture
A lot of modern apps use:
- Object storage for user-generated content and static files
- Local disk only for temporary processing
- Database for metadata and file references
If you tell me these 3 things, I can recommend the right option:
- What kinds of files are you storing?
- Do multiple app servers need to access the same files at once?
- Does your app expect a mounted filesystem path, or can it use an API?
