Simple FTP Service

Simple FTP Service overview

What a Simple FTP Service is - FTP, FTPS, SFTP and SCP access to your own cloud storage, running in three regions with no servers to manage.
Updated August 27, 2026

A Simple FTP Service (SFS) gives you a fully managed file-transfer server in front of your own cloud storage. You bring the bucket; DocEvent provides the hostname, the protocols, the users and the logging. Files are streamed straight through to your storage - nothing is staged or copied to DocEvent disks.

Supported storage backends

  • Amazon S3
  • S3-compatible services - MinIO, Wasabi, Supabase and other path-style endpoints
  • Azure Blob Storage, Azure Files and Azure Data Lake Gen2
  • Google Cloud Storage

Supported protocols

Once your service is created, your users can connect with any of:

  • SFTP and SCP (port 22)
  • FTP and explicit FTPS (port 21)
  • implicit FTPS (port 990)

You can disable plain FTP per service if you want to require encryption (the "block insecure FTP" option).

Regions

Simple FTP Service runs in three regions - pick the one closest to your users or your storage:

  • us-east-1 (N. Virginia)
  • eu-west-1 (Ireland)
  • ap-southeast-2 (Sydney)

Each region has its own hostname (sfs-<region>.docevent.io) and its own static IP addresses for firewalled environments.

High availability

Services run on auto-scaling clusters of multiple servers per region, deployed blue/green so upgrades roll out without dropping connections - see Scaling and connection handling for how in-flight transfers are protected during scaling events.
