If you want a managed file service for app files instead of operating SMB or NFS yourself, the usual choice on AWS is:
- Amazon EFS (Elastic File System) — managed NFS
- Amazon FSx — managed file systems for specific needs:
- FSx for Windows File Server — managed SMB
- FSx for Lustre — high-performance HPC
- FSx for NetApp ONTAP — advanced enterprise features
- FSx for OpenZFS — Linux/Unix-style file workloads
Quick rule of thumb
- Need Linux app shared storage? → EFS
- Need Windows apps / SMB shares? → FSx for Windows File Server
- Need enterprise file features? → FSx for ONTAP
- Need very high performance / specialized workloads? → FSx for Lustre
If you tell me your app platform (Linux, Windows, Kubernetes, EC2, etc.) and whether you need shared read/write access, I can recommend the best fit.
